EPM-PS1 PC/104-Plus Power Supply Module  PC/104-Plus form factor  50 Watt continuous output  RoHS-compliant Overview Highlights The EPM-PS1 is a plug-in 50 Watt power supply in a standard PC/104 3.55” x 3.775” PC/104-Plus Form Factor (90 mm x 96 mm) format. It is designed to power a stack of PC/104 and/or PC/104-Plus boards. Industry standard form factor stacks with compatible CPUs and The compact design is an excellent choice for systems with limited space for an internal or expansion modules. external power supply. This high reliability DC/DC switching power supply is designed for Input Protection use in applications such as transportation, medical, defense, and autonomous robotics. It is Diode protected against input polarity reversal. Transient voltage ideal for OEMs where long-term availability (5+ years) and rugged design are critical. When suppression provides enhanced ESD protection. used with VersaLogic’s other stackable CPU and expansion boards the EPM-PS1 enables complete system designs. Efficient Design Engineered for maximum power efficiency and optimum thermal management. Details Power Connectors The EPM-PS1 power supply provides up to 50 Watts of continuous output power. This PC/104-Plus Power is provided to the PC/104 stack via the PC/104-Plus expansion module is diode protected against polarity reversal up to 40 Volts and fuse protected power pins or a 4-position screw terminal connector. against over-current up to 10 Amps. TTL Level Disable Inputs Enables unused power supplies to be shut down to save power or can be used as on/off power switches. RoHS-compliant Full compliance with EU Directive 2002/95/EC for devices used in Europe.
