SDG #115 Miniwave MDP-XP MDP-M01 MDP-P905 Mini Power Supply

The Miniwave MDP series takes an unusual approach to bench power: instead of one large box, the system splits into a digital control and monitoring head (the MDP-M01) and separate programmable output modules (the MDP-P905), with the MDP-XP bundle bringing the pieces together. The appeal is obvious for anyone working on a crowded desk, since each module is roughly the footprint of a small handheld instrument yet still offers voltage and current setting, readback, and data logging style display features normally found on far bigger supplies.

The review looks at how well that miniaturised design actually performs once you start drawing current. Key questions for a buyer are setpoint accuracy against an external meter, how tightly the module regulates under changing load, output ripple and switching noise, and whether the thermal design can sustain the claimed output rather than only hitting it briefly. Because these modules are switching designs rather than linear, noise on the rail matters a great deal if you intend to power sensitive analogue or RF circuitry, and that is a trade-off worth understanding before spending money.

Equally important is the practical side: how the wireless link between the monitor head and output module behaves, how intuitive the interface is for quick adjustments, the quality of the terminals and connectors, and what you see inside when the case comes apart. Build quality and component choice inside a compact switching supply tell you a lot about long-term reliability and safety.

For hobbyists short on bench space, the MDP concept is genuinely clever. Whether it replaces a conventional linear supply depends on how much noise your projects tolerate and how much you value portability over raw performance.
