The PS2000L is a versatile power supply that can be used in a variety of Audiocom
intercom system applications. It directly accepts any AC input power from 100 to 240
VAC, 50/60 Hz, and it can be configured to power two separate intercom channels or
one large intercom channel with twice the intercom station capacity. Additionally, the
PS2000L can be configured for compatibility with Clear-Com* Intercom Systems. The
PS2000L can be rack mounted or used on a desktop. For rack mounting, optional hard-
ware is required. For desktop use, four non-marring rubber feet are supplied.

2. Channel Status Indicators and Reset Pushbutton: The indicators are green for normal operation and red when there is an overload or short circuit. The Reset pushbutton restores normal operation after the short-circuit or overload has been

of 100-240 VAC, 50/60 Hz.

Combine position, each channel is still powered separately, but the audio signals
are combined so that all users on both channels can intercommunicate.
