General Specifications:
Input
Voltage 12, 24 or 48 VDC depending on the model.
Protection the unit will shut down when the input voltage is either too low or too high. It will restart once the input voltage is within the normal operating range.
Output
Voltage: stabilised 12, 24 or 48 VDC, depending on the model. Other voltages are possible on special request.
Charger: the unit can be used as a battery charger by manually adjusting the output voltage.
Sense: the output has a separate sense connector that can be used to compensate for the voltage drop on the output cable. The compensation can be up to 1V (12 VDC output) or 2 Volt (24 VDC output) 24 models
Current 10 or 20 A, depending on the model, with current limiting.
Ripple: 100 mV tt
Safety: the module has a galvanic isolation between the input and output that can withstand 500 VDC at least.
Protection: the output is fully protected against short circuits or overload
Inverter
High Frequency (25 kHz) switching converter with an efficiency >90% (most models typical 93%).
Alarm
The unit has a relay alarm output (with both NO and NC contacts) that will generate an alarm when the unit shuts down because the:
- input voltage is too low or too high
- output voltage is too low (due to overload or a short circuit)
- temperature of the cooling blocks rises above +70°C.
Environmental
Module operating temperature: -20°C – +50°C but this is depending on the chassis or extra cooling blocks used.
The unit will shutdown when the temperature of the cooling blocks rises above +70°C. It will restart after cooling down to normal operating temperatures.
Dimensions
Open frame module: 174 x 157 x 58 mm
