Features: 1. The voltage and current (current limiting value) are set by numerical control. The voltage step is 0.01V/0.1V, the current step is 0.001A/0.01A, and the display is accurate.2. LCD displays statistics of input voltage, output voltage, temperature, current, , capacity and time. With USB female output, it is convenient to connect USB fan and other USB interface devices.3. Screw free quick wiring terminal, press type wiring and wire pulling, no need to screw, convenient and fast. With intelligent fast charging decoy, it can solve the problem of insufficient supply of USB input port. It supports mainstream fast charging protocols, QC2.0 3.0, SCP , and can also select no deception or automatic deception mode.4. High 15W, 2A current, can be used for fan speed regulation, desktop supply, adjustable charger, router supply, etc. Adjust the output voltage at will, and limit the current to 0-2A (wide input 4-13V, wide output 1-30V at will, with short circuit protection, short circuit will not burn)5. As a USB charging line, the charging voltage and maximum charging current can be adjusted at will (any voltage, with constant current, anti back , meeting the charging requirements of batteries)Multiple protection (short circuit, over-current, over temperature, over , over-voltage protection, charging anti reverse protection)Specifications:Input voltage: 4-13VOutput voltage: 1-30VOutput current: 0-2AOutput : less than 15WVoltage display: resolution 0.01V, factory precision (0.5%+3 words)Current display: resolution 0.001A, range 0-2A, factory precision (0.5%+3 words) display: 0.00W-15.0WTemperature protectionWorking current: about 30mACharging anti backflow: Yes, it can be directly connected to the battery for charging without adding a diodeShort circuit protection: YesSize: 80 x 40 x 16mmMaterial: PCB+Metalcolour: BlackPackage Contents:1 x -DP3D CNC USB Supply ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
