PS-2001L

Power Supply

The PS-2001L is a versatile power supply that can be used in a variety of Telex Audiocom intercom system applications. It direct-

ly accept any AC input power from 100 to 240 VAC, 50/60 Hz and can be congured to power two separate intercom channels

or one large intercom channel with twice the intercom station capacity. Additionally, the unit can be congured for compatibility

with Clear-Com Intercom Systems. The unit may be rack mounted or used on a desktop. For rack mounting, optional hardware

is required. For desktop use, four non-marring rubber feet are supplied.

Combine / Isolate Switch

When in the Combine position, the unit will combine the

audio signals of the two channels to create a single audio

channel where all users can intercommunicate. When in the

Isolate position, the unit will create two groups of completely

independent users.

Channel Status Indicators

The indicators are green for normal operation and red when

there is an overload or short circuit. The circuitry in the unit

will automatically reset when the overload or short circuit is

located and xed.

Universal AC Power Input

The unit accepts any input power in the range of 100-240

VAC, 50/60 Hz.

Instantaneous Auto-Reset

Instantaneous Auto Reset (IAR), the newest technology in

performance and safety, which uses a revolutionary new

circuitry that dynamically monitors line fault conditions. Then,

when the fault is removed, automatically brings individual

power supply channels up.

Intercom Channel Connectors

When the Combine / Isolate switch is set to the Isolate posi-

tion, each channel connector is powered separately and has

completely separate intercom audio. When the Combine /

Isolate switch is set to the Combine position, each channel is

still powered separately, but the audio signals are combined

so that all users on both channels can intercommunicate.

BAL / UNBAL Selector Switch

This selector switch allows the user to congure the unit for

use in either an Telex Audiocom (BALANCED) or Clear-Com

(UNBALANCED) system. Compatibility includes channel

connector pin-outs, channel power requirements, and call

signaling requirements. The default setting for this switch is

in the Telex Audiocom (BAL) position.
