CONDUCTION COOLED BOARD WITH FULL -40 TO +85C OPERATING RANGE

Manufacturer: Aitech
AITECH P231
Introduction

Designed for harsh environment applications, the Aitech P231 is a versatile and reliable modular 3U power supply. Its wide input voltage range (9 – 36 Vdc) assures excellent load and line regulation.

An integral input line filter is used to reduce the input reflected ripple.

The P231 has a total power output capacity of up to 100 W, providing four standard output voltages (5, 3.3, 12, -12 Vdc), making it ideal for use in VME, CompactPCI, and VPX systems. Input to output isolation is of 500 V minimum, thus eliminating any possibility of ground loops.

All outputs are individually protected against short circuit and overvoltage. The power supply asserts the three control signals: ACFAIL#, SYSFAIL#, and SYSRST#. The 5 Vdc and 12 Vdc outputs have sense lines to ensure voltage stability for high current loads.

A discrete input enables the power supply to be turned on and off remotely. Indicator LEDs provide a convenient visual indication of output voltage status.
