SynQor Introduces 4 kW Programmable AC-DC Power Supply for Military Applications

SynQor has unveiled its latest innovation, the MPPS-4000-270, a compact and lightweight high-output voltage programmable power supply, designed for military field use. The device can accept a 3-phase input ranging from 360-528 Vrms L-L and is capable of delivering an output voltage of 25 to 400 V (DC), with full power available between 175 and 400 V (DC). 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 24 A. The MPPS is ideal for a variety of applications including powering pulse loads, high capacitive loads, and battery charging.

The MPPS power supply boasts exceptional compliance with military standards, including MIL-STD-1399-300B, 461F, and 810G. This advanced device offers a solution to the challenge of unbalanced 3-phase loads commonly encountered on naval vessels. Adhering to MIL-STD-1399-300B, the MPPS 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. 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 offers remarkable versatility and 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. The MPPS 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-based module allows real-time remote monitoring, with trap/email features to alert users and monitoring consoles of important system events. The MPPS outperforms other products in its class, delivering superior output power, efficiency, reliability, flexibility, size and weight.
