1.0 Important Safety Instructions

Please read all safety, installation, and operating instructions before attempting to install or operate the unit.

!

DANGER

High voltages are present inside the unit. Do not reach inside while it is energized. This unit contains no user-

serviceable parts.

2.0 Warnings Defined

DANGER

Indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. This

signal word is limited to the most extreme situations.

WARNING

Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury.

CAUTION

Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury. It may

also be used to alert against unsafe practices.

3.0 Introduction

The SolaHD Micro/Mini Computer Regulator (MCR) provides voltage regulation and isolation from both

transverse and common mode noise for any type of load. It also suppresses transients with ferroresonant,

protects overloads, and serves as a dedicated line. It is the ultimate in ac power conditioning equipment.

4.0 Installation Instructions

4.1 Receiving

Upon receipt, immediately inspect the unit for obvious signs of shipping damage and/or mishandling. If

damaged, photograph the unit, inform the carrier, and contact your SolaHD representative.

4.2 Mounting, Ventilation and Important Factors to Consider

These units are for use in an indoor humidity and temperature controlled environment. Mount the unit in

either a horizontal or vertical position. The unit should be located where contact with the transformer’s hot

surface is unlikely. If mounted in a vertical position (e.g., on a wall), steel mounting hardware must be selected

in accordance with Table 1. The wiring compartment should also be facing up.

When utilizing MCR units, please consider these important factors:

• Motor or Inductive Loads: The MCR and CVS products have a fast response time and a built-in overload

protection which causes the output voltage to collapse during an overload condition. Due to this

protection function, the load must not draw more than the unit's rated capacity, even momentarily. For

this reason, care needs to be considered with highly inductive loads (e.g., motors, pumps, contactors,

solenoids, air conditioners, etc.).

You may size the conditioner based on the peak current rating, but you will need to meet the Minimum

Load requirement. This is the reason why SolaHD highly recommends only using these CVS and

MCR products for resistive or electronic loads.

• Minimum Load: Minimum loading of no less than 40% of the nominal rating because output voltage will

rise by 1% as the load is decreased. Units with less than 40% load may run hotter than those at close to full

load. This may result in overheating in the long run.

• Frequency: The output voltage varies linearly with changes in Input Frequency. A 1% change in input

frequency will yield a 1.5% change in output voltage. 60Hz models cannot be used with 50Hz application

and vice versa. This is also the reason why we don't recommend these units with generator source that has

varying input frequency.

All regulators generate a considerable amount of heat and depend on natural convection for adequate

cooling. It is important that ventilation openings not be obstructed. Mounting in a conned or poorly

ventilated space should be avoided, unless special provisions have been made for ventilation. For proper

ventilation, allow a minimum of 12 inches of clearance above the unit and minimum of 6 inches of clearance

on each side.

5.0 Parallel & Three-Phase Connections

5.1 Parallel Operation

Units of the same SolaHD catalog number may be connected in parallel to obtain a larger load capacity. Both

input and output connections must be made in parallel (see Figure 11). The SolaHD catalog number must end

in -8 or -C8 and must be larger than 1 kVA. No portable units can be paralleled.

All input and output paralleling wires must be tied together in an external paralleling “box” provided by the

user. Do not attempt to jumper the wires of one unit to the terminal block of the other unit. The terminal

block may not be rated to carry the total currents of both units. The input of each unit must be properly and

separately fused.

CAUTION! Failure to adhere to these requirements may damage the windings.

For units smaller than 5 kVA: When connecting in parallel the 208 Volt windings, other output voltage ratings

(120 V, 240 V) can’t be paralleled at the same time and vice versa. It is suggested that the installer remove X2

grounding on each unit, then connect X2 from each unit to one location and ground at that location only.

5.2 Three-Phase Connection Operation

Loads requiring 4-wire WYE connection may be served by three ferroresonant power conditioners with the

same SolaHD catalog number. The inputs must be connected in Delta. Input fuses must be connected in the

primary of each unit, not in the three-phase lines. The outputs must be connected in WYE with the neutral

solidly connected to a WYE load. Alternatively, these three outputs may serve three independent single-phase

loads. Phase angles may vary somewhat from 120 degrees even with balanced loading.

This circuit arrangement is not intended to serve single-phase line-to-line loading or three-phase Delta

loading. Outputs must serve three independent, single-phase loads of the same total Volt-Amphere (VA)

rating. Connections should be made in one of two ways as shown in Figure 11.

The outputs of the unit are isolated from the input lines. Voltage generated by internal leakage currents will

occur with respect to ground, which can have undesirable effects in electronic equipment. Therefore, if circuit

“B” is used, it is suggested that the installer remove X2 grounding on -8 units, then connect all X2 from each

phase to one location and ground at that location only. This is not required for circuit “A” and will not affect

regulation or the ability to reject power line noise or transients. s.

6.0 Operating Notes & Data

DANGER! High voltages are present inside the unit. Do not reach inside while it is energized. To measure

voltage, de-energize the unit, connect the meter, and then re-energize the unit.

6.1 Checking with Voltmeters

All input and output voltage measurements should be made with a true RMS voltmeter. A certain amount of

harmonics in the output may cause other types—particularly rectier types—to give inaccurate indications.

6.2 Load Regulation

Changes in output voltage resulting from changes in resistive loads, from no load to full load (100% pF), are

approximately 4%.

6.3 Effect of Load Power Factor

“Median” value of output voltage will vary from the label rating if the load has a power factor different

from the unit’s design. Load regulation will also be greater as the inductive load power factor is decreased.

However, the resulting median values of output voltage will be regulated against supply line changes at any

reasonable load or load power factor.

FIGURE 12

6.4 Operation with Switch-Mode Power Supplies

If an MCR is used as a source for a switch-mode power supply, a slight amount of ringing may be noticed on

the sine wave output of the unit at half cycle intervals for a short duration. This ringing occurs at the point

when the switch-mode power supply current demand drops to zero. The ringing need not be a cause for

concern since it is of relatively low magnitude and frequency. Both series have been tested with a variety of

switch-mode power supplies and it has been determined that the ringing does not affect the dc outputs, nor

has it been found to degrade the components of any switch-mode power supply.

Page: 19

MCR Hardwired Series – 50 Hz & 60 Hz

A272-282 Rev. 4 02/2020

6.5 Effect of Frequency

Changes in the frequency of the supply voltage will be directly reected in the output voltage. A change of

about 1.8% in output voltage will occur for every 1% change in input frequency, and in the same direction as

the frequency change.

6.6 Response Time

An important advantage of the SolaHD principle of static magnetic regulation is its exceedingly fast response

time compared with other types of ac regulators. Transient changes in supply voltage are usually corrected

with 1-1/2 cycles or less; the output voltage will not uctuate more than a few percent.

6.7 Input Characteristics

The MCR’s transformer includes a resonant circuit, which is energized whether it is serving a load or not.

Therefore, the input current at no load is approximately 35% of the full-load level, even at light or no load.

Input power factor will average 90–100% at full load, but may drop to about 75% at half load and 25% at no

load. In any case, it is always leading.

6.8 Current Limitations

When the load is increased beyond the MCR’s rated value, a point is reached where the output voltage

suddenly collapses and will not regain its normal value until the load is partially released. Under short-circuit

conditions, the load current is limited to approximately twice of the rated full-load value, and the input power

to less than 10% of normal. The unit will protect both itself and its load against damage from excessive fault

currents. Fusing of load circuits is not necessary.

6.9 Operation with Motor Loads

Because of the current-limiting effect described above, special attention should be given to motor

applications. In general, the regulator must have a load rating nearly equal to the maximum power drawn

during the starting cycle. This may run from two to eight times the normal (running) rating of the motor. In

doubtful cases, it is advisable to measure the actual starting current.

7.0 Service & Maintenance

7.1 Service & Maintenance

The unit is a simple, rugged device with no moving parts. Routine service and/or maintenance is not required.

If a problem does occur, please refer to “8.0 Troubleshooting” or contact SolaHD Technical Support for

assistance.

7.2 Field Replacement of Capacitors

Capacitors used in our units are the highest commercial grade, with each one given a rigid acceptance test

upon receipt. SolaHD guarantees free replacement of any capacitors which fail within one year of sale. Older

units can be replaced at a moderate charge.

NOTE: It may be possible to test and identify defective capacitors in the eld. Please contact SolaHD Technical

Support at 1.800.377.4384 or 1.847.268.6651 for further assistance.

8.0 Troubleshooting

Table 24: Troubleshooting

Problem Action

Nominal voltage too high

1. The load may be considerably less than the full rating. See “6.2 Load Regulation”.

2. The load may have a leading power factor.

Nominal voltage too low

1. The load power factor may be lagging.

2. The unit may be slightly overloaded. See “6.8 Current Limitations”.

Unit does not regulate closely

1. The unit may be slightly overloaded. See “6.8 Current Limitations”.

2. The actual line voltage swings may be outside the rate range of the unit, particularly on

the low side.

3. On varying loads, a certain amount of load regulation may be mixed with the line voltage

regulating action. See “6.2 Load Regulation”.

Output voltage is very low (20–60 V)

1. Unsuspected or unplanned overloads of substantial size may occur intermittently (motor-

starting currents, solenoid inrush currents, etc.). See “6.8 Current Limitations”.

2. One or more capacitors in the regulator may be defective.

No output voltage

1. Check power source breakers or fuses.

2. Check input switch.

3. Check continuity between input terminals, and also between output terminals.

Transformer operating temperature

1. The transformer used in the unit is designed to operate at high ux density and relatively

high temperatures. After connection to the line for 30 minutes or so, the transformer core

structure may be too hot to touch with your bare hands. This is normal and should not

cause concern.

Unit is operating, but does not appear

to have the correct output

The steps below will usually establish whether the apparent poor performance is due to a

fault in the unit or to some peculiarity of the working load.

1. Disconnect the working load.

2. Connect a dummy load of lamps, heaters, or other resistive loads (substantially equal to

the full load rating of the regulator) directly across the output terminals.

3. Measure the output voltage of the regulator (using a true RMS type voltmeter) directly

across the output terminals.
