DC-DC 400W 15A Adjustable Buck Converter, DC 10.5V-60V to 0.5V-45V Power Supply Module Ideal for Battery Charging & Power Supplies

Tired of underpowered or fixed-voltage modules that can't keep up with your projects? The Amicikart 400W DC-DC Buck Converter gives you full control — adjustable voltage from 0.5V to 45V and current up to 15A, all from a single compact module built for serious makers, engineers, and hobbyists.

This is not your average step-down converter. With a wide input range of DC 10.5V–60V, it works seamlessly with solar panels, lithium battery packs, lab bench supplies, and vehicle power systems. The output is continuously adjustable via onboard potentiometers for both voltage and current, making it perfect for CC-CV battery charging (Li-ion, LiFePO4, lead-acid), DIY variable power supplies, motor speed control, and LED driver applications. Operating at 100kHz with up to 97% conversion efficiency, it runs cool and clean — and with built-in short-circuit protection, a 15A input fuse, and reverse-polarity safeguard, your connected devices stay safe even during setup errors.

Designed for real-world Indian conditions, this module handles an operating temperature range of -10°C to 85°C and supports continuous 280W output (12A) in a ventilated environment — scale up to 400W with added heatsinking. A blue LED work indicator and dedicated constant-current indicator keep you informed at a glance. Note: A beep on first power-up simply means output voltage hasn't been set yet — adjust the potentiometer to your target voltage and the alert clears immediately.

Backed by a 1-year warranty and India-based support via WhatsApp, call, or email — Amicikart stands behind every unit. Free shipping all over India, same-day dispatch for orders before 2 PM, and COD available.
