PS-31

System Power Supply

The Model PS-31 supplies 32 volts of regulated DC power to each of three intercom channels. It has short circuit and thermal

overload protection, with automatic recovery when the fault is removed.

Program Input

There is a program input connector on the rear panel. A

channel assign switch on the front panel assigns the pro-

gram to any of the three channels. A level control adjusts the

program level to the intercom channel.

Status Indicators

There is an audible alarm and a red fault indicator for current

overload indication on any of the three channels. An audible

alert switch on the front panel turns the alarm on or off, but

the fault indicator will continue to ash during current over-

load conditions. There is also a green status indicator for

each channel. Each of these indicators will remain lit during

normal operation, but will turn off during a channel current

overload condition. Output current is automatically reduced

during an overload and normal operation is restored when

the overload is removed.

Input Power

The PS-31 is available in two versions: one for 115 VAC op-

eration and one for 230 VAC operation. A power on/off switch

is provided on the front panel.

Intercom Channel Connections

Intercom channels are connected to the rear panel of the

PS-31. A variety of connector pin-outs is provided to accom-

modate individual system requirements.

Impedance Selection

The PS-31 provides the required channel terminating imped-

ance for each channel. A 200/400 Ω impedance select switch

for each channel is located on the rear panel. These switch-

es are set to 200 Ω for normal operation. The 400 Ω setting

permits two PS-31’s to be coupled to double the DC capacity

of the system.
