Features: 1. Voltage and current (current limit value) are set by digital 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, power, capacity, and time. With a female USB output, it is convenient to connect USB fans and other USB interface devices. 3. Screw-free quick-release terminal, wire press and pull type connection, no screwing, convenient and fast. With intelligent fast charging protocol, it can solve the problem of insufficient power of the USB input port. It supports mainstream fast charging protocols, QC2.0 3.0, FCP SCP AFC, and can also choose the mode without cheating or automatic cheating. 4. High power 15W, current 2A, can be used for fan speed regulation, desktop power supply, adjustable charger, router power supply, etc. Adjust the output voltage at will and limit the current to 0-2A (4-13V wide input, 1-30V wide output at will, with short-circuit protection, short circuit will not burn) 5. As a USB charging cable, the charging voltage and the maximum charging current can be adjusted at will (any voltage, constant current, anti-reverse, meeting the charging requirements of most batteries) Multiple protections (short circuit, overcurrent, over-temperature, overpower, overvoltage protection, anti-reverse charging protection) Specifications: Input voltage: 4-13V Output voltage: 1-30V Output current: 0-2A Output power: less than 15W Voltage display: resolution 0.01V, factory accuracy ± (0.5% + 3 words) Current display: resolution 0.001A, range 0-2A, factory accuracy ± (0.5% + 3 words) Power display: 0.00W-15.0W Thermal protection Working current: about 30mA Anti-backflow charging: Yes, it can be connected directly to the battery to charge it without adding a diode Short-circuit protection: Yes Size: 80 x 40 x 16 mm Material: PCB+Metal Color: Black Package Contents: 1 x ZK-DP3D CNC USB Power Supply Module Only the above package, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture to be slightly different from the real one. The allowed measurement error is +/- 1-3 cm.
