MIL-STD-1275E Compliance Unit for Ground Vehicles (28 VDC (4.2 kW))
MIL-STD-1275E Compliance Unit for Ground Vehicles (28 VDC (4.2 kW))
GDM0200AD115U082 28 VDC (4.2 kW) MIL-STD-1275E Compliance Unit for Ground Vehicles; It distrubutes the battery voltage it receives from the platform to which it is connected, from the transient regime pulses defined in the relevant standard, and transmits it to the in-vehicle units connected to its output.
The unit has the capacity to deliver 150 amperes of output current and 4.2 kW output power at nominal input voltage.
The unit’s minimum efficiency is over 98% at peak output power. Cooling of the unit is provided by the cooler mounted outside the box and by conduction. There is no need for forced airflow.
