U20504 Used QJE QJ-PS30SWI Switching Power Supply

This pre-owned QJE QJ-PS30SWI switching power supply is in very good cosmetic condition, exhibiting only small, light surface scratches on a side panel from standard shack handling. The front faceplate, analog meter face, toggle switches, and rotary dials remain clean, sharp, and well-preserved. Please note that the unit presents a detectable odor consistent with prior kitchen or storage exposure. It comes complete with a standard 3-prong AC power cord and the printed instruction manual.

The QJE QJ-PS30SWI is a compact, high-efficiency switching mode DC regulated power supply designed specifically for amateur radio communications equipment. Delivering up to 30 Amps peak (13.8V DC nominal output), it provides clean, stable power to run 100-watt HF transceivers, VHF/UHF mobile rigs, or accessories without taking up valuable desktop space. To eliminate potential pulse noise common to switching circuits, the front panel features a dedicated Noise Offset control to shift switching frequency pulses completely out of your operating receiver bandwidth. It is equipped with an illuminated dual-function analog meter (switchable between Voltage and Amperage), a front-panel 10A automotive accessory socket, and heavy-duty 30A rear binding posts.
