Author: Marius Lubbe ZS1ML
The MFJ-4245MVP Deluxe Switching Power Supply isn’t just another piece of equipment in my ham radio shack; it’s a true veteran that has stood the test of time. In a hobby where technology rapidly evolves and the demand for reliable equipment remains constant, this power supply has proven its mettle over the years. Its longevity is a testament to its design and build quality, which has allowed it to remain a relevant and trusted companion for amateur radio operators across generations.
This powerhouse of a power supply, with its capability to deliver a hefty 45 amps maximum current and 40 amps continuously at 13.8 Vdc, has seen many operators through countless contacts, contests, and critical communications. It’s been there during the heat of summer field days, through the chill of winter nights during those low-band DX chases, and everything in between.
The MFJ-4245MVP has not just survived but thrived in a variety of environments, from the controlled conditions of a well-tended shack to the unpredictability of portable operations in the field. Its ability to adapt to different voltages and its array of output options have catered to the needs of every kind of radio setup imaginable. The unit’s fan, modulating its speed with the load, demonstrates an attention to detail that contributes to the power supply’s durability by preventing overheating, even under the most intense operating scenarios.
The built-in protective measures, like the automatic shutoff at over 45 amps and the spare fuse storage, are features that have surely extended the life of many radios by safeguarding them against electrical mishaps. These features, along with its solid performance, are why the MFJ-4245MVP is not just a product; it’s a legacy in the amateur radio community.
Beyond the normal binding posts, cigarette lighter style connector and banana plug ports there is a nod to the latest in the modern age with the inclusion of 45Amp PowerPoles.
As we look to the future of ham radio, it’s clear that the MFJ-4245MVP will continue to be a linchpin in the shacks of operators who value reliability, flexibility, and performance. It’s a power supply that doesn’t merely power a radio; it powers a hobby, a passion, and in many cases, a lifeline to the world.
With such a reliable piece of equipment at the heart of your station, here are some future-focused applications you might consider:
- Setting up a remote ham radio station that can be operated from anywhere in the world.
- Developing an educational program that uses ham radio to teach STEM concepts.
- Designing a disaster preparedness communications kit that can be rapidly deployed when needed.
