Feature: 1. USB Quick Charging: the machine has built-in fast charging protocol identification chip that supports USB fast charging function. 2. Safety Operation: it has over voltage conservation(OVP), over current conservation(OCP), over temperature conservation and the upgraded short circuit alarm function. 3. Adjustable Output Voltage \u0026 Current: output voltage and output current can be continuously adjusted between 0 and nominal value with fine regulating and coarse regulating. 4. Clearly Display \u0026 Functional: LED 4 digits display of voltage, current and power, high precision and features of voltage stabilization, current limiting, and simple operation. 5. Wide Application: can be used in mobile phone maintenance, computer maintenance, electrical maintenance, school laboratories scientific research and production line use and all other need DC regulated power supply. 6. Supporting Fast Charging Protocols Include: compatible with qualcomm QC2.0, QC3.0, iOS, Huawei FCP, SCP Samsung AFC and other fast charging protocols Specification: The DPS series product is a high-precision switch type DC regulated power supply with three windows and four positions display, which can simultaneously display voltage, current, and power. The product is widely used for mobile phone repair, computer repair, school and production line use, and its output voltage and output current can be continuously adjustable using an encoder. The stability and ripple coefficient of the power supply are very good, and the machine has a perfect OCP short-circuit conservation circuit. Its small size, beautiful design, convenient operation, and ability to work at full load for long periods of time are deeply loved by users.
