PS-702 Two-Channel Intercom Power Supply

PS-702 Front view

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.
