Telex PS-1F Single-Channel Intercom Power Supply

The PS-1F is a single-channel intercom power supply built to disappear into a wall. It flush-mounts in a standard two-gang electrical box, so a fixed installation can put channel power right where the line needs it instead of running everything back to a rack. It delivers up to 500 mA on one channel, enough to feed a run of beltpacks and speaker stations on a two-wire party line.

Pigtail power leads and binding-post channel connectors make the wiring straightforward for an installer, and the supply operates balanced only, matching Telex/Audiocom two-wire practice. For permanent broadcast, studio, and stage-comm builds it is the clean way to distribute intercom power without a visible box.
