Military Configurable Power Supplies (MTQ)

MultiQor Configurable Multi-Output Military DC-DC Power Supplies with EMI filter

The MultiQor Plate format of input-filtered DC-DC power supplies provides up to FOUR customer defined output voltages that are isolated from the input, each other and the cold plate. Using SynQor’s Mil-COTS line of high efficiency, high reliability, fixed switching frequency DC-DC converters and EMI filters, this supply is designed to comply with MIL-STD‑704, MIL-STD‑1275, DEF-STAN 61-5 and MIL-STD-461 for a 28Vin system when continuous full power operation is only needed down to 18Vin. The complete assembly is designed to withstand the harsh conditions of Military and Aerospace applications and is compliant with MIL‑STD‑810 requirements.
