Martek Releases 400W Power Module With Active PFC & Isolated DC Output

Martek Power, Inc. announced the release of the MW400S 400W single output ac-dc power module . The highly reliable, off-theshelf module is suitable for military, industrial and aerospace applications. Measuring 6.5 x 8.0 x 1.0" (165 x 203 x 25.4 mm) in size, the MW400S is a 400W converter with active ac Power Factor Correction and a built in EMI Filter.

The unit accommodates a universal single phase input from 90 – 265Vac at 47-440 Hz. Line harmonics meet MIL-STD-1399 for 60Hz or 400Hz. Conducted EMI meets CE101 and CE102 of MIL-STD-461 without requiring any external filtering. The converter provides isolated 2, 3.3, 5, 12, 15, or 28Vdc outputs. Power Factor is 0.99.

Standard features include remote turn on/off (TTL control), output voltage trim, overvoltage protection, overcurrent protection, AC Good TTL signal, DC Good TTL Signal, fixed frequency (500-550kHz) conversion with synchronization input. These, along with full specified performance (no derating) over an operating temperature range of -40 to +100°C from no load to full load, make the MW400S stand out in the mission critical segment. All models are available in I (unscreened) and M (screened) versions.
