Power Interface Module
The PWR-80 power interface module accepts power from the
console’s (dual failsafe) rackmounted SPS-40 power supplies and
feeds it to the TV-80 console. In the unlikely event of a power supply
failure, the panel automatically switches over to the second redundant
supply so the console continues uninterrupted operation.
The front panel of this module has test points and status LED
indicators for the console’s V+, V–, phantom power and digital V+
power rails. The test points allow these rails to be checked under load.
Pinout details for the module’s rear panel connectors are shown below.
