WinSystems' PPM-DC-ATX-P is a PC/104-Plus module that produces five regulated DC voltages from a common DC input. It features a very wide voltage input range from 10 to 50 volts. This allows the unit to operate with 12, 24, or 48 volt battery or distributed DC power systems.

This high-efficiency power supply design supports ATX compatible signals so it can use power management modes. ATX mode support Power On/Off , Power Good, and +5VSB to allow software controlled shutdown and sleep modes.

Each output is short circuit protected and current limited. A minimum load is not needed to bring the supply into regulation.

When power is applied to the board, five LEDs will illuminate providing a visual status that power is available for the +5V, +3.3V, ±12V, and +5V standby. If one of these LEDs is not lit or is pulsing ON and OFF, then the respective supply voltage is not in regulation. A pulsating LED is an indication that the respective converter is in current limit.

There is also a connector for an ON/OFF switch for remote shutdown of the system. However, the +5VSB source will continue to be active.
