SynQor has unveiled the MPPS-4000-270, a compact and lightweight high output voltage programmable power supply designed specially for military field use.
The device can accept a three-phase input ranging from 360-528 VrmsL-L and is capable of delivering an output voltage of 25 to 400 Vdc, with full power available between 175 and 400 Vdc. As a safety measure, it comes equipped with a user-programmable current limit mode in which it can run indefinitely and can be set from 0.2 to 24A. The MPPS is ideal for a variety of applications including powering pulse loads, high capacitive loads and battery charging.
The MPPS power supply features high compliance with military 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, maintaining 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. The MPPS is built to withstand extremely harsh environmental conditions including rain, sand, salt, high altitude and a temperature range of -40 °C to +70 °C.
The MPPS provides an array of features that make it a valuable asset for today’s military field operations groups. It has the ability to be configured in parallel with up to 32 units, providing increased power output or N+M redundant systems. It features internal control systems that allow for synchronized start and stop of the parallel group, making it function as a single power supply. The device also has a battle short feature, which enables it to continue functioning beyond the specified temperature range. Additionally, an SNMP Ethernet base module allows real-time remote monitoring, with trap/email features to alert users and monitoring consoles of important system events.
