WPC SHIPBOARD POWER SYSTEM – MIL-STD-1399 COMPLIANT

The water-cooled WPC Shipboard Power System is another example of Nova Electric’s abilities to design and manufacture cutting edge COTS power sources for custom applications.

Essentially, the WPC is a compact, lightweight, militarized AC-DC power supply and AC-AC frequency converter all in one.  This advanced unit converts an input of 115VAC, 60Hz, Three-Phase line-to-line to 208VAC, 400Hz, Three-Phase line-to-line (2KW), and additionally to six DC outputs (1 KW), for a total power output of 3KW. With a total efficiency of 80%, the unit runs reliably with a moderate amount of water flow for cooling.

 

The WPC supply is compliant to MIL-STD-1399 Table I, section 300 in all respects.  The power factor and current harmonics in the input side are fully compliant to MIL-STD-1399, and further, it withstands the 1000V transient of this standard.  All other static and dynamic requirements of the standard are met in full.

The capacity of the WPC to conform to the difficult requirements of MIL-STD-1399 is a result of a breakthrough design of an advanced Power-Entry-Module (PEM), which provides isolated DC to the various converters and inverters contained within the supply, while reflecting back to the input source a load of almost unity power factor, and very low current harmonics.  This module has also proven its extreme ruggedness in its ability to sustain the punishment of the 1000V transient with 4 ohm source impedance called for by MIL-STD 1399.

In addition to its MIL-STD-1399 compliance, the WPC also complies with the environmental standards of MIL-STD-810 for shipboard applications, and portions of MIL-STD-461 as well.

Like most of Nova Electric’s numerous other custom designs, the WPC fully complies to the classification of COTS.  It employs high-grade commercial components, and is nonetheless able to meet demanding military specifications.  This supply offers extraordinary performance, the rugged construction required to withstand severe environments, and compliance to major military standards (MIL-STD-1399, MIL-STD-810, and MIL-STD-461) at a moderate price.
