Telex PS2001L

The PS2001 power supply supplies two isolated channels of intercom system phantom power to down line components. Intercom power channels may be combined via the Combine/Isolate switch to form a single intercom power channel with double the capacity for large party-line applications. The PS2001 may be combined with a US2000A User Station to create a two channel master station configuration or as a stand alone power supply. The resultant Master Station would be a headset only station, as the PS2001 does not have an integrated speaker. Rack mountable in a variety of modular configurations with one of several optional rack mount kits. Like all of Audiocom's new two channel power supplies the PS2001 now comes standard with revolutionary IAR (Instantaneous Auto Reset) technology for performance and safety. This and all Audiocom power supplies can operate in an unbalanced mode to be completely Clear-Com® compatible.

Features

• 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.
• Combine/Isolate Switch
  • Combines the audio signal of the two channels to create one powerful channel. Press the switch to combine the channels or leave the switch depressed to isolate the two channels.
• Intercom Channel Connectors
  • When the Isolate position on the Combine/Isolate switch is selected, each channel connector is individually powered and has completely separate intercom audio. When the Combine position is selected, each channel is still powered separately, but the audio sign
• Balanced and Unbalanced Selector Switch
  • Gives the user the choice to configure the unit for use in either an Audiocom® (Balanced) or Clear-Com (Unbalanced) system. The default setting is for “balanced”.
