Description
Catel PS-2500B Power Supply for Video Modulator +12.6V -15V DC 110-250VAC
The Catel PS-2500B is a compact dual-output DC power supply designed to power Catel video modulator equipment. It provides two regulated DC output voltages — +12.6V and -15V — through front-panel banana jacks, and accepts a wide-range AC input (110–250VAC) making it compatible with both North American and international mains power. The unit was manufactured by Catel in Santa Clara, California.

Applications
The PS-2500B was designed as a dedicated power supply for Catel video modulator systems — equipment used in cable television headends and distribution systems to convert baseband video and audio signals into RF channels for transmission over coaxial cable networks. This type of dedicated power supply provides the specific dual-polarity voltages (+12.6V / -15V) that the associated modulator electronics require, keeping the RF signal chain cleanly powered without relying on a shared or generic supply. Catel was a Santa Clara-based manufacturer active in the cable TV equipment market primarily in the 1970s through 1990s, and their modulator and headend products were widely deployed in community antenna and early cable systems across the United States. Replacement or spare power supplies like the PS-2500B remain useful to operators maintaining legacy cable headend equipment still in service, as well as to collectors and technicians working with vintage CATV systems.
This Catel PS-2500B Video Modulator Power Supply has been inspected and appears to be in good used condition. The enclosure is clean with minor scuffing consistent with normal bench or rack use. The front panel toggle switch and banana jack outputs (+12.6V, GND, -15V) are intact and show no damage. The rating label on the rear is fully legible, and the attached AC line cord is present and undamaged. This unit was pulled from a working environment.
