INSTRUCTIONS

1) Description: DIN rail mountable primary switched-mode power supply with 90...265Vac - 110…345Vdc input, suitable for Single phase main line and DC line.

Functions:

 Power supply: the units can be used as standard power supplies with 12-15V/7A (-12 Version) and 24V/5A (-24 Version) output rating.

 Battery charger: charging current regulator limits the charging current to 0.8A, thus avoiding higher charging currents dangerous for the battery life.

 DC UPS function: in case of the power supply incapacity of supplying the load (mains failure or unit failure) the load will continue to receive power from the battery without ANY

interruption, until the mains recovers or the battery reaches the “Deep Discharge Voltage” threshold ( 9.5V for -12 Version and 19V for -24 Version).

 Deep discharge protection: disconnects the battery from the load when its voltage is lower than 9.5V (-12 Version) or 19V (-24 Version).

The higher the charging current the higher the temperature of the battery, therefore the battery life increases if deep discharge is avoided (the battery life depends also by the numbers

of the charge/discharge cycles, their durations and by other various factors).

 Battery reverse polarity protection: in case of reverse connection of the battery the resettable fuse will trip and protect all circuitry.

 Auto-resetting short circuit protection: connected in series to the line fed by the battery (the power supply output is actively protected against short circuit and overload)

 Status signals: a green LED, a red LED and a dry SPST contact displays the working status of the product, indicating “Load on Power Supply “ or “Load on Battery” .

2) Installation: use DIN-rails according to EN 60715. Installation should be made vertically (see Fig.4). For better device stability fix the rail to the wall close to the point where the device is to

be mounted. In order to guarantee sufficient convection, we recommend observing a minimum distance to other modules (see Fig.3).

The device is provided with a thermal protection, a limited air flow can causes the thermal protection tripping.

The SMPS automatically restarts after cooling.

To get normal operation reduce the temperature of the air surrounding the power supply, increase the ventilation or reduce the load.

3) Connections: the device is equipped with pluggable screw terminals. To avoid sparks, do not connect or disconnect the connectors before having previously turned-off input power and

waited capacitors discharge.

In order to comply with UL certification, use appropriate copper cables of indicated cross section, designed for an operating temperatures of 60°C (for ambient <45°C) and 75°C (for ambient <

60°C).

Strip the connecting ends of the wires according to the indication on Fig.5 and ensure that all strands of a stranded wire enter the terminal connection.

4) Input protection : the device input is provided with varistors against overvoltage. Input isn’t provided with internal fuses, thus an external short circuit/overcurrent protection must be

provided by the end user (see Fig.6).

For operation on a single-phase system, a protection fuse on the phase must be provided.

5) AC input connection: the device can be connected to single-phase AC lines with Un 120…240 Vac (see Fig.7).

6) DC input connection: connect L terminal to + pole, N terminal to – pole and I terminal to GND. Rated voltage 110...345Vdc.

The device is also suitable for photovoltaic or wind turbine applications.

7) Output connection: the device is suitable for SELV and PELV circuitry.

Uout can be adjusted with a potentiometer (see Fig.1)

Check Uout before connecting the power supply to the load. With output voltage set to the max. value, the continuous current must not exceed the nominal power.

8) Parallel connection and redundancy: not recommended.

9) Output protection: the device is protected against overload (OL) / short circuit (SC) / overvoltage (OV) / overtemperature (OT).

OL and SC: are controlled by an hiccup auto-reset protection with the following behaviour:

OL behaviour: Max. OL = In x 1.5 with constant output voltage. If the current is ≥ In x 1.5 the unit enters the OL protection and starts an ON/OFF cycle (hiccup).

SC behaviour: the device supplies the indicated short circuit peak current for 50 ms if the output current exceeds In x 1.5 the device enters into a controlled ON/OFF cycles (hiccup mode).

The output voltage drops to a voltage value depending on the impedance of the failed load circuit.

Output OV circuit protection: the output is protected against potential OV due to internal malfunction or coming from the load for Uout  Unom x 1.2 – 1.3, depending on the model.

OT protection: turns off the device if the internal temperature exceeds a safe limit. The Battery can continue to supply the Load.

The device restarts automatically after cooling down. To recover to normal operation reduce air temperature surrounding the power supply, increase cooling or reduce load.

When operating at normal load and > 45°C reduce the output power with 4.0W/°C.

10) Feeding DC motors: it is possible to feed DC motors considering that when a motor starts-up under effort its consumption is much higher than the nominal current and it can trigger

overcurrent protection.

NOTE: motors can generate high conducted noise on the DC line. Therefore it is not recommended to feed on the same line motors and equipment sensitive to noise.

11) Warranty: the devices are guaranteed free from factory defects for the time specified in the “Sales Conditions”

Failures caused by misuse, external and/or abnormal events (i.e. overvoltage, over temperatures) or non-respect of above parameters and standards, are not covered by warranty.

Opening the housing of the product makes warranty to be no longer valid.

In order to improve the products Nextys SA reserves the right to change product specifications, ratings and data without previous advice.

NOTES:

 The total current sunk by the load and by the battery during the max. current required by the charging process (0.8A), must not exceed 7A (-12 Version ), 5A (-24 Version) continuous,

thus the max. continuous load must be 6.2A (-12 Version)/ 4.2A (-24 Version).

 The charging time of the battery depends on its capacity in Ah, on its charge level, on ambient temperature, on the efficiency status of the battery, its age, on the charging voltage of the

device (recommended: 14.4V for -12 version, 27.5V for -24 version).

 Normally the charging current of lead batteries must not exceed 10% of rated Ah. Higher charging current reduces battery life, too low charging current leads to a longer charging time

and incomplete charge.

 Lead batteries in normal charge conditions and efficiency have a good self regulating capacity on charging current, independently form the current supplied by the charger.

 To calculate the duration of voltage/current that a battery can supply, refer to the data sheet of the battery. Basically the Ah that a lead battery can supply depends on its efficiency

status, on the charge level and other factors such as T ambient (low ambient temperatures reduces the capacity of the battery) ageing reduces the capacity of the battery.

The average life span of a properly used lead battery is 4/5 years.
