Description
The PS-2001L and SPS-2001 are versatile power supplies that can be used in a variety of Audiocom® intercom
system applications. They both directly 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 units can be configured for compatibility with Clear-Com* Intercom Systems. The units
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. The SPS-2001 also provides a speaker with two mixed inputs making it ideal
for situations calling for a master station with a microphone / speaker combination.
