Telex PS-4001 Four Channel Power Supply For Wired Intercoms, XLR-3M audio connector, 100 to 240V AC Input Power, 24 ½1V DC Output Power

The PS-4001 power supply supplies four (4) isolated channels of intercom system phantom power to down line components. Use it as a stand alone power supply to supply four (4) independent party line channels. Or, use it in conjunction with an ES-4000A expansion station to create additional intercom channels when using a US-2002/PS-2001L or US-2002/SPS-2001 Master Station configuration. IT can operate in either balanced or unbalanced mode, making it completely Clear-Com compatible.

Instantaneous Auto-Reset Instantaneous Auto Reset (IAR), the newest technology in performance and safety, which uses a revolutionary new circuitry that dynamically monitors line fault conditions. Then, when the fault is removed, automatically brings individual power supply channels up. Channel Status indicators are used to show status; green for normal operation and red to warn of an overload or short circuit. The system resets itself once the overload or short circuit is corrected.

Acts as a connector to ES-4000A.This connector carries power to the ES-4000A expansion station and carries the four (4) audio channels of the ES-4000A. When a ES-4000A is connected to the PS-4001, each of the four (4) channels of audio is "broken out" to the respective channel connector. Intercom Channel Connectors carry power to the intercom system and provide termination for the audio signal of each intercom channel. Balanced and Unbalanced Selector Switch gives the user the choice to configure the unit for use in either an RTS Audiocom (Balanced) or Clear-Com (Unbalanced) system. The default setting is for "balanced".
