Hayes 52-00005 Modem Power Supply 13.5VAC 700mA 9.5VA 4-Pin Special Connector
The Hayes 52-00005 is an original OEM wall-mount power supply designed exclusively for Hayes modems requiring a 13.5VAC power source. It is a Class 2 plug-in transformer with a proprietary 4-pin output connector, and is rated at 13.5VAC, 700mA (0.7A), and 9.5VA. The unit plugs directly into a standard 120VAC / 60Hz outlet and delivers the AC output the Hayes modem expects — making it a direct, correct replacement for a lost or failed original supply.

Applications
Hayes Microcomputer Products was the dominant manufacturer of dial-up modems for personal computers from the late 1970s through the 1990s, and its Smartmodem line — including the Smartmodem 1200, 2400, and later models — set the standard for modem communication and the AT command set still referenced today. These modems used a proprietary power connector rather than a standard barrel jack, which means the 52-00005 supply is the correct and often only direct replacement when the original is lost. This supply is relevant to anyone maintaining, restoring, or operating a Hayes modem from that era, including collectors of vintage computing hardware and institutions keeping legacy dial-up or POTS-based equipment operational.
This Hayes 52-00005 modem power supply has been tested and confirmed to be in working order — it powers on a compatible Hayes modem as intended. The unit shows light cosmetic wear consistent with age, including some fading and scuffing on the label, visible in our photos. The cable and 4-pin output connector appear intact and undamaged. We have had multiple units in stock, so the specific unit you receive may vary slightly from the one photographed, but will be functionally equivalent. Please view our photo set and contact us if you have any questions.
