Ul Certification EE49 CERTIFICATION EE49 220V AC TO 24V DC TRANSFORMER ELECTRONIC TRANSFORMER MANUFACTURE

The power transformer is a soft magnetic electromagnetic component whose functions are power transmission, voltage conversion and insulation isolation. It is widely used in power supply technology and power electronics technology. According to the size of the transmission power, the power transformer can be divided into several files: 10kVA or more for high power, 10kVA to 0.5kVA for medium power, 0.5kVA to 25VA for low power, and 25VA for micropower.
