Aitech P217 - Rugged/Mil 3U VME Power Supply Board

Rear Power Connector, for Harsh Environments, -55 to +85°C Qualified

Introduction

Two DC to DC converter modules are used to provide four isolated outputs with a power rating of up to 140W. To ensure top performance and noise reduction, Aitech used two converters made by the same manufacturer. The DC to DC converters feature a minimum of 500V isolation from input to output, eliminating any possibility of ground loops. Moreover the DC to DC converters are equipped with thermal shutdown capability. Each output channel has an independent current limitation. A line filter is used to reduce the reflected ripple in the inputs. The input power voltage can vary from 18 VDC to 36 VDC. Outputs are protected against short circuit and overvoltage.
