CAN PSU Documentation and Framework Component

Introduction

The CAN Power Supply Unit (PSU) is used to provide power to ELMBs remotely via the CAN bus, allows for software control of the power (on or off) and allows for the current and voltage to be monitored. The PSU is a rack mounted unit and can supply up to 16 CANbuses with the voltage required. Each bus is supplied by 2 sources of power: CAN power (12V/25W) and AD power (12V/35W).

A JCOP Framework component has been developed to allow for easy integration of the control for the PSU into PVSS: fwElmbPSU.

For Atlas Users, a framework component to control PSU and monitor ELMBs from the FSM has been developed: fwElmbPsuFSM.
