60V-72V to 12V 20A 240W DC to DC Converter
The WEHO WH-C60721220 is a high-performance DC-DC buck converter designed for applications requiring a stable 12VDC output from a high 60V-72VDC input. Delivering 240W of power at 20A, it operates with an impressive 95% efficiency to keep thermal levels low. It accommodates a wide input voltage range of 40V to 90VDC, allowing for stable performance even during significant source voltage fluctuations. The mechanical design features a 100x80x38mm aluminum heat-sink frame, which is essential for dissipating heat during sustained high-load operations. Like other models in the series, it is fully sealed and waterproof, making it suitable for mounting in exposed locations. Safety features include over-current protection and short-circuit protection, ensuring the device survives temporary electrical surges without permanent damage.
