DC-DC Buck Converter, XH-M404 DC 4-40V to 1.25-36V 8A 200W Step-Down Module

Struggling with unstable voltage for your DIY electronics project? The XH-M404 DC-DC Buck Converter gives you rock-solid, adjustable power output from virtually any DC source — all under ₹500.

This compact step-down module accepts a wide input range of 4V to 40V DC and delivers a precisely adjustable output from 1.25V to 36V, making it compatible with solar panels, lithium battery packs, vehicle power rails, and bench power supplies alike. With a maximum output of 8A and 200W, it handles demanding loads with ease — and the built-in 0.36-inch red digital voltmeter display lets you monitor output voltage in real time without needing a separate multimeter. No guesswork, no surprises.

What sets the XH-M404 apart is its combination of 95% conversion efficiency at 180KHz switching frequency and a three-layer protection system — short-circuit protection, input reverse polarity protection, and over-temperature protection — that safeguards both the module and your connected devices. Whether you are a hobbyist building a custom power supply, an engineer prototyping a circuit, or a maker powering an Arduino or Raspberry Pi setup, this module delivers reliable, energy-efficient regulation without breaking the bank.
