Clear-Com PS702
2 Channel Intercom Power Supply


The PS-702 can supply up to 2 amps at 30 volts DC to two channels in a 1-RU. 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.

Clear-Com's advanced fail-safe design can sense the difference between a short and an overload. Should a problem occur, each channel's DC overload/fault LED identifies the power supply's response to the problem: solid means an overload is sensed, but still powered; blinking means power has been temporarily cut off to protect the power supply. If both channels are operating and one channel has a fault, the other channel will continue to operate normally. Power is restored to the shorted or overloaded channel in a little as .5 seconds. With our exclusive 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. This can be quite handy for trouble-shooting or simply a time saver when quick access to either intercom line is needed. A 440Hz tone is available on either or both channels and is indispensable for system diagnostics and set-up. Simply flip a switch, set a level, and go.

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 singlechannel unit by using the front-panel A+B link switch.
