Description

Overview

The EPM-PS1 is a plug-in 50 Watt power supply in a standard PC/104 3.55" x 3.775" (90 mm x 96 mm) format. It is designed to power a stack of PC/104 and/or PC/104-Plus boards. The compact design is an excellent choice for systems with limited space for an internal or external power supply. This high reliability DC/DC switching power supply is designed for use in applications such as transportation, medical, defense, and autonomous robotics. It is ideal for OEMs where long-term availability (5+ years) and rugged design are critical. When used with VersaLogic's other stackable CPU and expansion boards the EPM-PS1 enables complete system designs.

The EPM-PS1 power supply provides up to 50 Watts of continuous output power. This PC/104-Plus expansion module is protected against diode polarity reversal and over-current of up to 40 Volts.

VersaLogic products are designed for use by OEMs working in a variety of market applications: Aerospace, Defense, Energy, Industrial, Security, Medical, Military, Robotics, and Transportation. Anywhere that the need for superb quality and high-performance embedded computing exists, applications include: automation, avionics, gateway, in-vehicle, monitoring, simulation, and vision.

VersaLogic delivers extremely reliable standard and customized embedded computers backed with unsurpassed service and the highest availability in the market. VersaLogic exists to exceed customers' product, service, support and delivery needs - whenever and wherever the need arises.
