Audiocom® Description 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.
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 located and fixed. 3. Universal AC Power Input: The PS2000L accepts any input power in the range of 100-240 VAC, 50/60 Hz. 4.
Audiocom® Installation Unpacking The package contains the following items. Contact the shipper or your Audiocom dealer immediately if anything is damaged or missing. Detach and fill out the registration card and return it to Telex to properly register your PS2000L.
Figure 2. Audiocom / Clear-Com Selector Switch (Top Cover Removed) Intercom Channel Connections Channel Capacity: When connecting intercom stations to the PS2000L, determine the total current for all stations on each channel. The total per channel should not exceed 2A. If you exceed this limit, the PS2000L will provide an overload indication. Note that if you are using DC wallpacks with any intercom stations, you do not need to add the current consumption of those stations to the total current.

Audiocom® Figure 5. Using two PS2000L Power Supplies to provide a greater capacity on each channel. Power-Up Check 1. ☞ Plug in any DC wallpacks that are being used with individual intercom stations. If you plug in DC wallpacks after applying power to the PS2000L, you may get an overload indication at the PS2000L. This is because the stations that are being powered by wallpacks will draw current from the PS2000L until their own DC supplies are connected. 2.
