Telex audiocom ps-2001l 用户手册

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 configured to power two separate intercom channels 

or one large intercom channel with twice the intercom station capacity. Additionally, the unit can be configured 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.

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.

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 fixed.

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

VAC, 50/60 Hz.

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.

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.

This selector switch allows the user to configure 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.
