Product introduction:
The PCB Mount Power Supply manufactured by Shenzhen Topow Electronics Co., Ltd., is a highly efficient and robust 36-watt switching power supply. This latest V4.0 version features key improvements including an output connector (replacing a cable) and conformal coating for enhanced durability in demanding environments. It accepts a universal AC input range from 90V to 264V and delivers a regulated 12V/3A DC output, making it suitable for a wide array of electronic equipment. The power supply is engineered with comprehensive protection features like over-current, short-circuit, and over-voltage protection (hiccup and latch modes). Complying with stringent safety (UL/EN 60950) and electromagnetic compatibility (EMI/EMS) standards, including EN55032 Class B, it ensures safe and interference-free operation. Its compact physical dimensions (100x45.5x23mm), natural convection cooling, and wide operating temperature range make it an ideal power solution for both consumer and industrial applications.
