U20314 Used Astron RS-35A Heavy-Duty Linear Power Supply

U20314 Used Astron RS-35A Heavy-Duty Linear Power Supply

Overall Condition: Used, good physical and functional condition! Shows light scuffs and minor surface marks on the heavy steel cabinet from normal shack placement, but presents well and is structurally very sturdy. Front panel ON/OFF rocker switch with integrated red power indicator, rear binding post terminals, heat sink fins, and attached AC power cord are all clean and solid.

An absolute industry workhorse in amateur radio shacks, the Astron RS-35A is a heavy-duty, linear-regulated 13.8V DC power supply engineered for continuous high-current performance. Built with a massive internal transformer and heavy rear external heat sink fins, linear power supplies like the RS-35A are prized by ham operators for generating clean, RF-quiet DC power free of the switching hash or hash noise associated with digital power supplies.

Delivering up to 35 Amps peak surge and 25 Amps continuous duty, it effortlessly powers standard 100W HF transceivers, VHF/UHF amplifiers, or multiple shack accessories simultaneously. Features fold-back current limiting and over-voltage crowbar protection to keep your sensitive radio gear safe.
