Innovative, tailored power conversion solutions designed end-to-end for military applications

We were approached by a client with a complex requirement for a cabin power supply module (CPSM). Milpower Source engineers developed this innovative solution to meet their unique requirement. Designed for a critical use airborne application, the M311 features specifications not seen in any other power conversion solution, including multi-drawer line replaceable supplies, liquid cooling and load capacitance.

Our client required a VPX VITA 62 DC/DC power supply with modified connectors and form factor for an airborne application. We started with one of our mature 3U VPX designs and modified it to create the VPX-3 to meet their needs.  It was designed to meet MIL-STD-461, MIL-STD-704, MIL-STD-810, MIL-STD-1275

The B&C AC+DC converter feature two split outputs (same output voltage) and up to 160W. Additional features include: high efficiency, wide input range, AC input / output isolation, fixed switching frequency (330KHz), EMI/RFI filters included, indefinite short circuit protection with auto-recovery and over-voltage protection. It was designed to meet MIL-STD-461, MIL-STD-704, MIL-STD-810 and MIL-STD-1275.

Generator Control Unit (GCU) designed for a rotorcraft application, this Generator Control Unit (GCU) provided the client with the required multi-output design and MIL-Standard qualifications.

Designed for a missile application, our engineering team successfully addressed the MIL-STD-810g Shock and Vibration requirements, while delivering a custom form factor DC/DC converter unit which met all of the other requirements the customer presented.

Designed as a standalone, high power factor, natural convection cooled converter.  This unit is deployed by multiple branches of the military, in all environments.  It features a rugged outdoor deployable free air convection cooled design and a max output of 1kW. It achieves an efficiency of 80% (typical) and is designed to meet MIL-STD-461F, CE102, CS101, CS114, CS115, CS116, RE102, RS101, RS103 and MIL-STD-810G.

Designed for an airborne application, the Transformer-Rectifier Unit (TRU) is a non-isolated, non-regulated, 3-phase AC/DC power supply, which is MIL-STD-704A and MIL-STD-461E compliant, delivers over 95% efficiency, and features up to a 18kW load, low input THDI (below 8%), and RS-422 communications.

Designed for a ground radar application, the Pulse Load Attenuator feeds a single PA, is sequenced (50V turns on 0.7s after other voltages) and hold up full power 3ms on input failure.

A 288-350VDC Filter and Control Unit (FCU) with 7 outputs, overload disconnection and embedded filtering. 

Up to 6.6kW (300V/22A) output, 28 VDC NiCad battery DC input, fixed switching frequency, short circuit recovery with ON command and over-voltage shutdown with ON command recovery. An efficiency rating of 84% (typical 86% at 22V input) and operating temperature of -40°C to +90°C (baseplate), with thermal sensor for baseplate monitoring. EMI/RFI filters are standard.  Lastly, it is designed to meet MIL-STD-461, MIL-STD-704 and MIL-STD-810.

A naturally convection cooled power supply designed to MIL-STD-1275B, with 24 outputs, up to 1.8kW continuous with no derating at -30°C to +55°C ambient.

We were approached by a client with a requirement for a 24-port military switch/router with D38999 connectors which are used in a wide variety of military systems. We changed the product design to include D38999 connectors instead of the existing SCE connectors, thus providing reliable performance in military harsh environments while maintain MIL-DTL-38999 standards.

Our client required a MILTECH 912 gigabit ethernet switch with modified connectors and form factor for naval application. We designed the solution to comply with military standards for naval vibration, thermal shock & corrosion necessary for lasting performance in salt spray conditions. We eliminated the captive screws, replaced all screws to 316 Stainless Steel and replaced all connectors to bronze and adding an anti-corrosion coating.

We were approached by a client with a requirement for a switch containing 26 x 1G LAN ports in a VMEbus backplane architecture, suitable for military environmental conditions. Our solution was based on the capabilities of the existing MILTECH 912 with additional LAN ports and other specific features.

Our client required the MILTECH 9136 embedded switch with a small carrier, connectors and voltage entrances which are designed for his specific needs. The MILTECH 9136 is a 87x87mm board-level switch with option for 52 ports. We designed a small carrier adapted to the dimensions of the switch with all customer's requirements.
