DC Power Sequencing Module

Document #:

LIGO-T1200284-x0

Document type:

T - Technical notes

Abstract:

A module has been designed utilizing solid state relays that allows a sequence to be controlled upon application of various DC power forms to a rack. The module will be mounted on top of each ISC rack. It will ensure the +/-24VDC power supplies will always be greater than the +/-18VDC power supplies. Upon loss of +24VDC, the +18VDC will shut off. A similar scenario exists for the -24/-18VDC power forms.
