Quasar Power Supply Configuration

Updated by Bryan Jones


This document applies the Power Supply configuration for the Quasar console frames only.


Quasar power supply modules (PSU) have a built-in load-sharing mechanism. This means that every PSU module constantly contributes power to the surface. No switching ever takes place if one should fail. This ends up being a much smarter way to handle redundancy.

Quasar can be configured with UP TO four power supply units per frame, depending on the frame size and the user requirements in terms of power redundancy.

The console frames always come standard with a non-redundant PSU configuration.

The following table describes the number of supplies as standard and the number of optional supplies.
