Descriptions: The biggest advantage of this product is that the components adopt SMT patch technology, built-in protective tube ,anti-reverse connection,is a multi-purpose converter. The MOS tube and the rectifier tube adopt the new original installation to make sure the safety and stability of the converter. The shell uses new aviation aluminum to heat the heat quickly. Decreasing PCB board area, circuit board wiring is more reasonable, system work steadily. Features: This converter adapter features high inverter frequency, quick response, small size, light weight, low energy consumption. High efficiency, energy saving energy,with a strong adaptability, such as low temperature, high temperature, humidity, corrosion, dust, vibration, etc. environment . Work steadily and with wide voltage. With reverse connection, overflows and short circuit protection, safe and reliable. The range of anti-voltage fluctuation is wide, the ability is strong, the control accuracy is high. The modular design of circuit structure are convenient for fast installation.
