The RTS
®
PS-20 is the new RTS
®
Two-Wire Intercom power supply. The PS-20 features
two- and four-channel operation, RTS
®
monitoring, two-channel program input,
audio linking, and three-mode operation: RTS
®
2-channel, RTS
®
4-channel and Clear-
Com
®
mode. It also has double the power output of the PS-31 per channel, which
will increase the number of user stations and beltpacks which can be connected
substantially.
The PS-20 features two channels of communication where both channels are “wet”,
meaning there is power on each channel (RTS
®
two-channel mode). In RTS
®
four-
channel mode, the audio signals and DC exist on the same wire. The PS-20 can also
be switched into Clear-Com
®
mode. The PS-20 has a 3-pin XLR (male) connector on
the front of the system, where a RTS
®
user station can connect and monitor activity
on either or both channels. A single PS-20 power supply has 1.8 ampere per channel
which means the user can power up more stations. If additional user stations or
beltpacks are needed, two PS-20’s can be joined together to double the power
capability. A pair of standard stereo plug connectors are available on the back of
the power supply to connect two PS-20’s through audio linking as well. The PGM
IN (3-pin XLR female Program Input) connector can be used to send audio to both
CH 1 and/or CH 2.

Output Input
1 amp at 32 VDC, 1 Amp per CH1 100 VAC or 230 VAC Version available, 50/60 Hz,
System power supply. Provides two independent output channels, one powered
at 32VDC up to 1 amp and one “dry” and program audio. Features unique circuitry
that protect outputs from short circuit conditions with automatic and instantaneous
recovery when short is removed. Powers an average of 15 stations. Packaged in ½
rack by 1 RU all metal housing for added durability.
Power supplies are the heart of partyline
intercom systems. They supply operating
voltage to beltpacks and many user stations.
Unique short circuit reset circuitry design and
unparalleled mechanical engineering ensures
reliable trouble-free operation for years to
come. With all of the things you have to worry
about, your power supplies should not be one
of them.
