2000 Watt Single Output Military Grade Power Supply

Product Description

2000 Watt Single Output Military Grade Power Supply This unit is a 2000 watt, single output, military grade power supply designed for electronic systems operating in harsh environments (subject to abnormal shock and vibration) and extreme temperature conditions. It is conduction cooled providing a -50° to +85° C operating temperature range. This highly reliable design will meet or exceed all applicable military standards including MIL-STD-810D & MIL-STD-461D.

DC Output Characteristics (Floating)

Output Power: 2000 Watts (maximum continuous power, may require derating for some low voltage outputs)
Line Regulation: ±1.0% Typical
Load Regulation: ±2.0% Typical (No load to full load; nominal input)
Output Ripple/Noise: 1% Typical (pk-pk; nominal input; full load; 20MHz bandwidth)
Set Point Accuracy: ± 1.0% of Output Voltage (Nominal input; full load; 25°C)
Transient Response: Output voltage returns to within 1% in less than 2.5mS for a 50% load change and the peak transient does not excess 5%.
Overshoot: Turn-on and turn-off overshoot should not exceed 5% over nominal voltage.

Electrical Characteristics
