U20423 Used Astron SS-30M Switching Power Supply 13.8Vdc/30A

Overall Condition: Used, great physical condition overall showing only minimal signs of handling! Cosmetic Details: The black metal top cover panel exhibits a minor, superficial scuff mark that is barely noticeable under normal lighting. The rest of the compact enclosure casing presents cleanly. Meters & Controls: Features dual illuminated analog meters (AMPS and VOLTS) and a lighted rocker power switch on the front faceplate, both clear and fully functional. Rear Panel & Connections: Heavy-duty rear DC output binding posts, active cooling fan shroud, 115V/230V voltage selector switch, and IEC AC power inlet are clean and solid. Comes complete with an AC power cord.

The Astron SS-30M is a high-efficiency, lightweight switching DC power supply engineered specifically for communications equipment and ham radio shacks. Designed to suppress RFI (Radio Frequency Interference) noise, it delivers up to 25 Amps continuous output at 13.8 VDC (30 Amps peak ICS), making it ideal for powering 100W HF transceivers, dual-band VHF/UHF mobiles, and desktop accessories.

Featuring built-in over-voltage protection, foldback current limiting, thermal shutdown safety, and an active rear cooling fan, the SS-30M offers reliable, heavy-duty power in a compact, portable form factor.
