This DC-DC converter module converts a nominal 48V (42V-61.5V) into 24V (25A maximum) accurate voltage at the output.

The unit comes with the option to set several similar modules in parallelTelecom Rectifier in order to gain more power and redundant operation (N+1).

Output voltage is set by a single trimmer-potentiometer, using a small screwdriver.

Each DC to DC Power Converter is protected against input low/high voltage, output over-voltage, over temperature and output over-load.

A low-voltage-disconnect (LVD) is included at the input stage to protect the potential battery at the input from being deeply discharged.

Galvanic isolation between input and output. There are four leds in the front panel which indicate the load level.

The DC Transformers are protected against input low/high voltage, output over-voltage, over temperature and output overload or shorting (short circuit). Each unit is Hot-Swap, 3 units in a 1U, 19″ shelf (total 1,800W per shelf).
