The 1-RU Clear-Com PS-702 can supply up to 2 amps at 30 volts DC to two channels. This is sufficient to power up to 40 beltpacks, 10 speaker stations or 12 headset stations even under the most demanding conditions. Either channel is capable of supplying up to 1.2 amps. The full current capacity may be divided between the two channels. Its advanced fail-safe design can sense the difference between a short and an overload. Power is restored to the shorted or overloaded channel in a little as .5 seconds. With its Intelligent Fault/Overload Sensing (IFOS), the PS-702 will dynamically increase this time period before attempting another reset until the fault or overload is corrected. This function significantly extends component life. And there is no need to disconnect stations for the power supply to reset.The unit also offers a convenient front panel intercom line jack, switchable to either channel. A 440Hz tone is available on either or both channels for system diagnostics and set-up. Like all current Clear-Com Party-Line power supplies, two or more units can be connected in parallel for increased system capacity or backup redundancy. Multiple units will automatically synchronize their response to power faults and overloads. The PS-702 can also operate as a single channel unit by using the front-panel A+B link switch.Main Features:Provides up to 2 amps in only 1RUSupports up to 40 beltpacks, 10 speaker stations or 12 headset stationsExclusive IFOS Intelligent Fault/Overload Sensing for system resetFront panel intercom line jack selectable for either channelA+B Link switch for single channel operationBalanced program input with global and individual channel controlsUniversal power supply accepts 100-240 VACOverload/fault indicator for each channelBuilt-in test tone generator for setup and diagnosticsSwitchable terminations for each channelWorks in parallel with other power supplies and main stationsUL Listed and CE certified
