Valcom VP-2148D 48VDC 2-Amp Power Supply
Overview
The VP-2148D is a regulated, filtered 48Vdc power supply built to run Valcom paging equipment that needs a stable 2-amp source rather than a bare wall-wart. It solves the common paging-closet problem of powering a horn or amplifier zone from a dedicated, code-friendly supply instead of daisy-chaining unregulated bricks. Rated for a 20-year service life under normal paging system load, the VP-2148D fits telecom rooms and IDF closets where the supply needs to sit on a rack rail or mount flush to a wall near an outlet.
Compatibility
The VP-2148D outputs 48 Vdc at 2 A regulated, sized for Valcom paging horns, amplifiers, and other 48-volt paging system components that draw within that current budget. Connection is via barrel or wire termination (6.5mm x 4.3mm x 1.7mm connector, center positive), with the mating wire assembly included — check the load's connector style before ordering if it isn't barrel-terminated.
Installation Notes
Input is universal 100-250 Vac, 50/60 Hz through an IEC-320-C14 receptacle, so it runs on standard power cords across domestic and international mains without a separate transformer. Rated output load is 0.93 A at 115V/60Hz with 107 VA apparent power draw — low enough that heat buildup in an enclosed rack isn't a real concern. The case is sealed black high-impact ABS, and the unit is listed for indoor use only, so don't spec it into an outdoor cabinet or unconditioned space. An output voltage LED gives a quick go/no-go check during commissioning without a meter. Dimensions run 1.50in H x 2.60in W x 6.61in L, small enough to tuck into a half-populated rack shelf or mount directly to a wall stud near the outlet it draws from. The Energy Star rating and low apparent power draw mean it meets federal and state energy requirements, relevant if the install is in a facility tracking energy compliance.
