Advanced field-grade three-phase programmable high output voltage power supply

SynQor, Inc. has unveiled the MPPS-4000-270, a compact, lightweight, high-output voltage programmable power supply designed for defence field use. The device can accept a three-phase input ranging from 360-528VrmsL-L and can deliver an output voltage of 25VDC to 400VDC, with full power available between 175VDC and 400VDC. As a safety measure, it comes supplied with a user-programmable current limit mode in which it can run indefinitely and be set from 0.2A to 24A. The device is ideal for various applications, including powering pulse loads, high capacitive loads and battery charging.

The power supply offers excellent compliance with defence standards, including MIL-STD-1399-300B, 461F and 810G. This advanced device offers a solution to the challenge of unbalanced three-phase loads commonly encountered on naval vessels. Adhering to MIL-STD-1399-300B, the device maintains a phase current balance within ±5% for ships and ±3% for submarines while providing tightly regulated DC power. The power supply's superior conducted and radiated emissions performance has been rigorously tested to meet MIL-STD-461F while also meeting MIL-STD-810G requirements for shock, drop and vibration. It is built to withstand extremely harsh environmental conditions, including rain, sand, salt, high altitude and a temperature range of -40C to +70C.

The power supply offers remarkable versatility and features, making it a valuable asset for today's defence field operations groups. It can be configured in parallel with up to 32 units, supplying increased power output or N+M redundant systems. The device features internal control systems that allow for synchronised start and stop of the parallel group, making it function as a single power supply. The device also has a battle short feature, which allows it to continue functioning beyond the specified temperature range. Also, an SNMP Ethernet-based module enables real-time remote monitoring, with trap/email features to alert users and monitoring consoles of important system events. It outperforms other products in its class, delivering superior output power, efficiency, reliability, flexibility, size and weight.
