Powerstax provides a wide range of high reliability mil spec DC-DC converters and pre-regulators, EMI filters, transient voltage suppressors and hold-up modules.
Typical applications for the Powerstax PX series include MIL and aviation systems and high reliability industrial applications.
Powerstax provides standard and custom power solutions for defence, homeland security, shipboard and ground systems and mobile/vehicle mounted wireless and radar systems, telecomm infrastructure and security systems.
DC-DC Power Converters
The PXH series of mil spec DC-DC converters provides the designer with a versatile and cost effective high reliability solution to their power requirements. The series is available in single and dual output versions. All models have an ultra-wide DC input range of 16-40V and output voltages of 3.3V, 5V, 5.2V, 12V, 15V, ±5V, ± 12V, ± 15VDC at power levels between 5W and 30W. The converters employ fixed high-frequency switching technology with an on-board input EMC filter and built-in soft start circuit. All modules have output short circuit and overload protection.
The PX32 series are high voltage output DC-DC converters with a output at voltages from 250V to 1800V at power levels from 16W to 20W. The input voltage range is 21.33V.
Pre-Regulator Modules
PXPG Series are designed to extend DC/DC converter input bus voltage to meet system operation during voltage transients, spikes, and drop out occurring in high reliability or other systems.
EMI Filters
The PF Series are high reliability EMI filter for use with the PX30 & PXH series DC-DC converters operating at less than 65W. These filter has been designed to reduce the input line reflected ripple current to within the limit of MIL-STD-461D, CE102.
Transient Voltage Suppressors

Hold-up Modules
Providing a hold time of 5-50µs/µF the PXHU series hold-up modules provide an alternative solution to reduce the amount of capacitance needed by charging the hold up capacitor at high voltage (typical 38VDC) while limiting the input current. This provides enough time to facilitate an orderly system shut-down in the event of a brown-out or complete power failure.
