Aircraft 115 VAC Power Supply Model M-164

The Aircraft Power Supply has three regulated outputs and will operate from 115 VAC 400 Hz aircraft power. All outputs have individual short circuit and over-voltage protection. All outputs are adjustable and isolated from each other, chassis, and from primary power. Fault indicators are provided on the front panel for all outputs. Output isolation enables the user to configure the power supply for many different output combinations such as dual 23 VDC outputs with isolated or common grounds, ±23 VDC outputs, and + or - 5 VDC output with common or isolated ground. The Power Supply is qualified to meet the EMC requirements of MIL-STD-461C and environmental requirements of MIL-STD-810D. The Power Supply includes EMI and RFI filtering for both input and output.
