Telex PS-4001 4-Channel Power Supply for RTS ES-4000A

The PS-4001 power supply supplies four (4) isolated channels of intercom system phantom power to down line components. Use the PS-4001 as a stand alone power supply to supply four (4) independent partyline 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. The PS-4001 can operate in either balanced or unbalanced mode, making it completely Clear-Com compatible.

Features:

• 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 itselfonce the overload or short circuit is corrected.
• 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 œbroken 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 œbalanced.

Channel Status Indicators
The indicators are 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 located.
