U20522 Used MFJ 30 Amp Switching Power Supply MFJ-4230MVP
This pre-owned MFJ-4230MVP switching power supply is in good operational condition with a solid chassis, showing visible surface scratches across the top cover and metal enclosure from prior shack use. The front faceplate is well-preserved, featuring clear panel lettering, functional power and fault indicators, smooth voltage adjustment, a responsive power switch, and clean front-panel binding posts. The backlit analog meter operates properly, and the rear Anderson Powerpole connections and cooling fan are intact. It comes complete with a standard 3-prong AC power cord.
The MFJ-4230MVP is an ultra-compact, lightweight 30-amp switching mode DC regulated power supply engineered specifically for powering modern amateur radio equipment. Capable of delivering up to 30 Amps surge and 25 Amps continuous duty, it handles 100-watt HF transceivers and VHF/UHF mobile rigs with ease. The front panel features a variable voltage adjustment knob (4V to 16V DC) with a detent for standard 13.8V operation, heavy-duty 5-way binding posts, and an analog meter switchable between voltage and amperage monitoring. On the rear, twin pairs of factory-installed Anderson Powerpole connectors allow quick, secure plug-and-play connections for modern go-boxes and station setups.
Cosmetic Condition: Good pre-owned condition. The metal chassis is structurally solid but shows heavy cosmetic surface scratches and finish wear along the top cover and housing.
Front Controls & Meter: Analog A/V meter face is clear, the voltage adjustment knob turns smoothly, and the power rocker switch and meter selector push-button actuate positively.
Terminals & Rear Panel: Front heavy-duty multi-way binding posts and rear Anderson Powerpole ports are clean, tight, and undamaged.
Cooling & Protection: Internal cooling fan spins freely, and rear AC input connector and 115V/230V selector switch are intact.
High-Current Output: Delivers up to 30 Amps peak / surge and 25 Amps continuous output, ideal for 100-watt HF and high-power VHF/UHF transceivers.
Variable Voltage Adjustment: Front-panel potentiometer adjusts DC voltage output from 4V to 16V with a fixed detent at 13.8V DC.
Dual Output Connections: Front-mounted 5-way binding posts plus rear dual Anderson Powerpole connectors for quick shack integration.
Dual-Function Analog Meter: Front push-button easily toggles the lighted meter between output Voltage (V) and Current (A).
Compact & Portable: Space-saving desktop footprint weighing less than 3 lbs, making it suitable for portable DXpeditions, emergency operations, or tight desks.
Built-in Protection: Engineered with over-voltage, short-circuit, and thermal protection with front LED power and fault status indicators.
