DC-DC 12v Buck Converter Voltage Regulator

The DC-DC 12V Buck Converter Voltage Regulator is a high-efficiency, non-isolated power converter designed for a wide range of automotive, industrial, and electronic applications. Featuring a robust die-cast aluminum shell, this voltage regulator is engineered for durability and optimal heat dissipation, ensuring reliable performance even in demanding environments.

This versatile DC-DC converter supports a broad input voltage range, accommodating DC 24V, 36V, 48V, 60V, 72V, 96V, 108V, and 120V, with input voltage ranges from 15V–40V, 15V–60V, 15V–75V, 15V–90V, and 40V–150V. It delivers a stable 12V DC output and is available in multiple output current options: 1A, 2A, 3A, 5A, 8A, and 10A, with output power ranging from 12W to 120W. The converter boasts a high conversion efficiency of ≥93%, a voltage regulation rate of 1%, and a load regulation rate of 2%, ensuring consistent and reliable power delivery for sensitive electronics and critical systems.

Designed for extreme conditions, the DC-DC 12V Buck Converter operates within a temperature range of -40°C to 80°C and features an IP68 waterproof rating, making it suitable for outdoor and harsh environments. The unit is protected against overload, over-current, over-temperature, and short-circuit events, with optional over-voltage protection for added safety. With a low no-load current of 50mA and a ripple voltage of just 100mV, this converter ensures stable and clean power output.

Natural air convection provides efficient cooling without the need for additional fans, and the compact size (66x60x22mm) and lightweight design (100g) make installation straightforward. The 13cm installation cable length offers flexibility for various mounting scenarios, and the product is securely packaged in an electrostatic bag and carton for safe delivery.
