Telex PS-4001
4 Channel Intercom Power Supply

The PS4001 power supply supplies four isolated channels of intercom system phantom power to down line components. The PS4001 may be combined with an ES4000A Expansion Station to create additional intercom channels when using a US2000A/PS20001 or US2000A/SPS2001 master station configuration. The PS4001 can also be used as a stand-alone power supply to provide power to four independent partyline channels. The PS4001 features IAR (Instantaneous Auto Reset) technology for performance and safety. Rack mountable in a variety of modular configurations with one of several optional rack mount kits. Can operate in an unbalanced mode to be completely Clear-Com compatible.

• 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.
• Connector to ES-4000A
  This connector carries power to the ES-4000A expansion station, and carries the four audio channels of the ES-4000A. When a Telex ES-4000A is connected to the PS-4001, each of the four channels of audio is "broken out" to the respective channel connector.
• Intercom Channel Connectors
  These 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 Telex Audiocom (Balanced) or Clear-Com (Unbalanced) system. The default setting is for "balanced".
• 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.
