PS-1 Intercom Power Supply

PS-1-PRI

The PS-1 is a highly regulated 24VDC, 2 Amp (continuous) power supply capable of supplying up to 66 BP-1 belt packs with all signal lights constantly lit.  It may be rack mounted or used as a table-top unit, when fitted with its optional plain side panels and plastic feet.

NOTE: Please contact your sales representative in order to specify which version of the PS-1 you would like, rack-mounted or table-top.

The PS-1 may be used alone to power a single-circuit system, or it may be combined with Production Intercom's MSM-1 to form what is commonly referred to as a Main, or Master Station.

The toroidal transformer used in the PS-1 provides greater efficiency, lower hum, and reduced strayfield radiation compared with conventional types, and allows the single rack unit configuration.  The transformer is multi-tap, allowing for operation at 100, 120, 220 or 240VAC.  There is sufficient iron in the core to accommodate 50 or 60Hz supply frequencies.  A convenient AC inlet permits supply voltage choices by removing and rotating the insert.  The regulator IC also provides protection against overloads and short circuits.  In the event of a protective shut-down, turning the main AC switch off and back on, after removing the short, will restore power to the system.

For the sake of economy and simplicity, the PS-1 has only one 3-pin XLR-type connector on the rear panel.  For more complex systems we recommend that you consider the PS-2.  That unit has the same cabinet and main components as the PS-1, but also has 3 XLR-type outlets, front panel switches to connect and disconnect the three circuits, and LED signal indicators for two of the circuits.

The steel cabinet, firmly secured components, and best-quality XLR-type connector all contribute to the PS-1's outstanding ability to withstand rough usage.
 
The PS-1 may be used with Clear-Com® and other less well-known unbalanced 200 ohm headset communications systems stations.
