Viking Electronics PS-1 AC Power Supply (120V AC / 13.8V AC)

Overview

The Viking Electronics PS-1 is a hardwired AC power supply that steps 120V AC input down to 13.8V AC at 1.25A output. The PS-1 ships with bare wire leads rather than a molded plug — designed for installations where the supply is wired directly into a terminal block or enclosure rather than plugged into a standard outlet. It is the correct choice when you need a dedicated, panel-integrated voltage source for Viking Electronics telephony and intercom equipment that specifies a 13.8V AC supply. If your installation calls for a standard plug-in version, the PS-1A covers the same voltage and current ratings with a molded plug attached.

Compatibility

The PS-1 is the designated replacement or supplemental supply for Viking Electronics equipment requiring 13.8V AC power — including the PS-48-RGA talk battery and ring voltage unit and related intercom and door entry systems in the Viking line. Verify your target device's power input spec matches 13.8V AC at 1.25A or less before ordering; this supply will not serve equipment requiring DC input or higher AC current. The 4-position screw terminal output block accommodates multi-conductor wiring common in telecom enclosures. For PoE-powered Viking products or installations requiring 48V DC, this supply is not applicable — consult the device's power requirements directly. Pair with appropriate low-voltage power supplies or enclosures for clean panel integration.

Installation Notes

Output is via a 4-position screw terminal — no plug, wires only. Input is standard 120V AC. The unit measures 135mm x 90mm x 45mm, making it suitable for mounting inside most telecom or intercom enclosures with available DIN or surface-mount space. Operating temperature range is 0°C to 32°C (32°F to 90°F) — this is a narrow thermal window; do not install in unventilated exterior enclosures or environments subject to temperature extremes. Humidity tolerance is 5% to 95% non-condensing. No plug means a licensed electrician or qualified installer must terminate the 120V AC input side per local electrical code. Review the Viking Electronics spare parts listings for the PS-1A if a plug-in variant is required.
