ASTRON RS-20A Linear DC Power Supply, 13.8VDC 20A Max Tested Works 30 Day Return


ASTRON RS-20A Linear DC Power Supply, 13.8VDC 20A Max Tested Works as can be seen with vault meter connected in photo, vault meter does not come with the power supply. That's there for test purposes only. The Astron RS-20A is a heavy-duty, linear regulated power supply widely used in ham radio and industrial communications. It is known for its durability and "clean" power output with minimal electrical noise. Core SpecificationsOutput Voltage: Fixed at 13.8 VDC, but internally adjustable from 11-15 VDC. 5 min on / 5 min off. Technology: Linear topology, which provides much lower ripple (less than 5 mV peak-to-peak) compared to switching power supplies.
Protection: Features fold-back current limiting (short circuit protection) and crowbar over-voltage protection (activates if output exceeds 16.7 VDC). Build: Heavy-duty exterior heat sink for passive cooling; weighs approximately 18 lbs.
