Description

These units may show signs of heavy wear but are in good working condition. Free ground shipping within the Contiguous United States. The RTS PS-31 Power Supply provides 32 volts of regulated DC power to three intercom channels, supporting reliable operation in professional RTS-style wired intercom systems. Designed for continuous duty, it includes short circuit and thermal overload protection with automatic recovery once the fault condition is removed. Program Input and Channel Assignment A dedicated program input connector on the rear panel lets you feed program audio into the system. Use the front-panel channel assign switch to route the program to any of the three channels, then set an appropriate feed level with the front-panel level control. Status Indicators and Overload Alerts The PS-31 provides clear fault visibility for fast troubleshooting. A red FAULT indicator flashes to show a current overload on any channel, and an audible alarm can be enabled or disabled via the front-panel AUDIBLE ALERT switch (the FAULT indication continues regardless). Each channel also has a green status indicator that remains lit during normal operation and turns off during an overload condition. During overload, output current is automatically reduced, and normal operation resumes when the overload is cleared. Rear-Panel Connectivity and Termination Intercom channel connections are made on the rear panel, with multiple connector pin-outs available to accommodate different system wiring requirements. Each channel also includes selectable terminating impedance using a rear-panel 200/400 ohm IMPEDANCE SELECT switch. The 200 ohm setting is used for normal operation, while the 400 ohm setting allows two PS-31 units to be coupled to increase the system’s DC capacity.
