USER INSTRUCTIONS
1) DESCRIPTION
Description: LDD240-WU can be supplied with any voltage between 11 VDC and 55 VDC, please respect the polarity. The output voltage can be programmed to any
voltage between 5 VDC and 55 VDC.
To prevent damage in case of reverse polarity, the device is protected by an internal not replaceable fuse. LDD240-WU can be used in SELV and PELV circuits.
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. 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 cause the thermal protection tripping.
The device automatically restarts after cooling.
To get normal operation reduce the temperature of the air surrounding the unit, 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 for internal capacitors discharge (minimum 1 minute)
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 up to 45°C
75°C for ambient up to 60°C
90°C for ambient up to 70°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) DC INPUT PROTECTION
LDD240-WU is equipped with internal fuse, ratings of DC line protection devices must be coordinated with input current indicated on the data sheet.
5) OVERLOAD (OL) / SHORT CIRCUIT (SC) / OVERVOLATGE (OVP) / OVERTEMPERATURE (OTP) PROTECTIONS
Hiccup auto-reset and constant current limitation, user selectable.
Overload behaviour in hiccup mode: the output current is limited at 1.5xImax. When the programmed Imax value is exceeded a timer is started. If the load current
demand is not reduced below Imax for maximum 5 seconds the output is switched off and kept off for 10 seconds.
Overload (OL) error message is shown on the display, this cycle is then repeated until the load current demand is not decreased below Imax.
Overload behaviour in constant current mode: the output current is limited at Imax. If the load asks for more current than Imax the output voltage is progressively
decreased to keep the output current regulated at Imax.
Short circuit behaviour: the output is switched off in about 0.2 seconds and kept off for 10 seconds. Short Circuit (SC) error message is shown on the display details.
This cycle is then repeated until the short circuit is removed.
Input/output overvoltage protection: the unit is protected against external overvoltage applied to the input; for input voltages greater than 62V the device will shut down.
In case of an internal failure, a double protection circuit switch off the output and avoid output voltage higher than 62V potentially dangerous for the supplied devices.
Overtemperature protection: The “Over Temperature (Ot)” error message appears when the internal temperature exceeds the safe limits. In this case the output is
switched off. The output is switched back on when the temperature decreased to safe limits.
6) STATUS SIGNALS
“DC OK” relay contact(24V/1A): Contact closes when the output voltage is present and within the product specified output voltage regulation range.
7) REDUNDANT AND PARALLEL CONNECTION
LDD240-WU is equipped with an internal ORing circuit allowing direct parallel connection for redundancy without the need of an external isolating diode. Parallel
connection for power increase can be achieved connecting the output of the devices in parallel. Please keep the length of the input and output cables of the 2 paralleled
units the same length and cross section to achieve the best possible current balancing. Avoid exceeding 80% of the total available output current. To use parallel
connection the operating mode shall be set to “Parallel (PA)” in the configuration menu.
8) 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.
9) WARRANTY
Power supplies 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.
INPUT PROTECTION
INPUT CONNECTIONS - DC LINE
Fuse MCB 6 A C curve or 4 A D curve.
For USA and Canada, use the fuse type closest to the European equivalent type. Surge protection:
it is strongly recommended to provide external surge arresters (SPD) according to local regulations.
