Applications
Executone was a major manufacturer of telephone systems and PBX equipment based in Milford, Connecticut, active from the 1980s through the 1990s. Their systems — including the ITS (Integrated Telephone System) and related key/hybrid telephone platforms — relied on dedicated external power supplies like the 550005 to deliver the multiple voltages needed by the system controller, line cards, and telephone sets simultaneously. The 48VDC output is the standard telephone industry feed voltage for powering station equipment, while the 24VDC and 90VAC 30Hz outputs serve internal system and ringing functions respectively. This supply is a direct replacement or spare for Executone installations still in operation, and is also sought by technicians servicing legacy Executone systems.
This Executone 550005 Telephone Power Supply has been pulled from a working environment where it was previously in service. It has not been powered up or tested at our facility. The unit appears to be in good used condition overall — the metal enclosure shows light surface wear and minor scuffing typical of removed telephone equipment, and the attached multi-conductor wiring harness with white molex-style output connectors appears intact. Please review our photos and contact us with any questions.
