The DPS series products are a three-window four-bit high-precision DC regulated power supply, which can display voltage, current and power at the same time. Power supply stability and ripple coefficient are very good, has two upgraded functions of USB fast charging and perfect short circuit protection. Can be widely used in mobile phone or computer maintenance, school and production line use, etc. Features: USB Quick Charging: the machine has built-in fast charging protocol identification chip that supports USB fast charging function. Safety Operation: it has over voltage protection(OVP), over current protection(OCP), over temperature protection and the upgraded short circuit alarm function. Adjustable Output Voltage andamp Current: output voltage and output current can be continuously adjusted between 0 and nominal value with fine regulating and coarse regulating. Clearly Display andamp Functional: LED 4 digits display of voltage, current and power, high precision and features of voltage stabilization, current limiting, and simple operation. 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.
