It is necessary to tear off the rear casing to make it look bright! ! ! 1. Highlights: • 1.15W power, 2A current, can be used to power the router. • 2. As a USB input adjustable desktop power supply, you can adjust the output voltage arbitrarily, limit the current 0-2A (wide input 4-13V, wide output 0.5-30V any adjustment, with short circuit protection, short circuit does not burn) • 3. As a USB charging cable, adjust the charging voltage and maximum charging current arbitrarily (any voltage, with constant current, anti-backflow, to meet the charging of most batteries) • 4. Multiple protection (short circuit, over current, over temperature, over power, over voltage protection, charging anti-backflow protection) 2. Product parameters: 2.1. Input voltage: 4-13V (When using pad input, pay attention to the positive and negative poles, do not connect AC power) 2.2. Output voltage: 0.5-30V 2.3. Output current: 0-2A (The output current in constant voltage mode is adaptive according to the load size, it is not adjustable. If you set the limit current to 1A, then the load current is greater than 1A, it will automatically enter constant current mode 1A ) 2.4. Output power: less than 15W (when the output power is greater than 15W, the output is automatically turned off, and the -OP- is displayed. After reducing the load power, press the ON/OFF button to solve). When the input current is too large, it may be turned off early due to temperature protection. 2.5. Voltage display: resolution 0.1V, factory accuracy ± 0.1V or so (can be manually corrected after comparison with standard voltmeter) 2.6. Current display: resolution 0.01A, range 0-2.2A, factory accuracy ±0.05A; display error is larger when the output current is less than 0.05A, small current within 10-40mA can not be displayed (can be manually corrected, output current Calibration is more accurate when it is greater than 1A, and calibration is not recommended for small currents.) 2.7. Power display: 0.00W-15.0W 2.8. Temperature protection: When the power component temperature is higher than 100 °C, enter the -OT-protection, reduce the load power, press the ON/OFF button to solve (the power will not enter the OT protection for long-term operation within 10W, when the input current is greater than At 3A, it may enter over-temperature protection when working for a long time, even if it does not reach 15W) 2.9. Working current: about 30mA 2.10. Charging anti-backflow: Yes, it can be directly connected to the battery for charging, no need to add a diode 2.11. Short circuit protection: Yes 2.12. Weight: High version 30g, low version 20g 3. Function description: 3.1. Button “SELECT” button: short press – switch between voltage, current, power, wheel display; long press – enter or exit calibration mode; “ON/OFF” button: Short press – control the output end to be turned on or off; long press – set the power-on default output to be off or on, long press for more than 3s to release, display ON for each power-on default There is an output, and the display OFF means that there is no output by default every time the power is turned on. 3.2. Potentiometer The current adjustment potentiometer CC rotates clockwise to increase the limit current value. When the load current reaches the limit current, it enters the constant current state (note that the output current can be increased without adjusting the potentiometer. At constant voltage, the output current is only Depending on the load, it varies according to the load); • Maximum output current (constant current value) setting method: switch to current display, directly short the output terminal to adjust the CC potentiometer, the current display current value is the maximum output current. The voltage adjustment potentiometer CV rotates clockwise to increase the output voltage. 3.3. Indicator lights CC——Constant current indicator light, bright when constant current (red); ON - output status indicator (green); 3.4. Input and output ports The input side - the left side, the USB male head, the microUSB, and the pad are selected as inputs; Output - right side, blue 2P terminal as output. 4. Accuracy calibration method: Output voltage calibration - When the digital tube always displays the voltage, press and hold the "SELECT" button for more than 3 seconds to release, the digital tube flashes, short press the "SELECT" button, the voltage value increases by one unit, short press the "ON/OFF" button The voltage value is reduced by one unit. When the output voltage is low, it may take several times to see the value change 0.1V.
