K7812MT-500R4 Mornsun 12V 0.5A Non-Isolated DC-DC Converter – High Efficiency

The K7812MT-500R4 Mornsun is a compact, high-efficiency non-isolated DC-DC converter designed for reliable 12V power regulation in industrial control, instrumentation, and power management systems. With a wide 15V to 36V input range and up to 92% efficiency, this converter provides stable output performance while maintaining extremely low no-load power consumption.

Its robust design includes short-circuit protection, excellent transient response, low ripple and noise, and a thermally efficient epoxy-encapsulated UL94 V-0 rated case. Operating at a switching frequency of 2.0MHz, the module supports compact PCB layouts and is ideal for space-restricted applications.
