Product parameters:
2.1. Input voltage: 4-13V (when using pad input, be careful not to connect the negative electrode, do not connect the AC)
2.2 output voltage: 0.5-30V
2.3. Output current: 0-2A (In constant voltage mode, the output current is self-adaptive according to the load size, not adjustable. If you set the limit current to 1A, then when the load current is greater than 1A, it will automatically enter the constant current mode, and the maximum output is 1A)
2.4. Output power: less than 15W (when the output power is greater than 15W, the output will be automatically turned OFF and the display will be -op -. After the load power is reduced, press the ON/OFF button to solve the problem).
Voltage display: resolution 0.1V, factory accuracy ±0.1V (if high precision requirements, can be compared with the standard voltmeter after manual correction)
2.6. Current display: resolution 0.01a, range 0-2.2A, factory accuracy ± 0.05a; When the output current is less than 0.05a, the display error is large, and the small current within 10-40mA cannot be displayed. (If the accuracy is high, manual correction can be compared with the standard ammeter. When the output current is greater than 1A, the calibration is more accurate, and it is not recommended to calibrate at the low current.)
2.7. Power display: 0.00W-15.0W
2.8. Temperature protection: When the temperature of power element is higher than 100℃, enter -OT-protection, reduce the load power, press ON/OFF button to solve the problem (power within 10W long-term work generally will not enter OT protection, when the input current is greater than 3A, long time work may enter overtemperature protection, even if it does not reach 15W)
2.9. Working current: about 30mA
2.10. Anti-charging: Yes, it can be directly connected to the battery for charging without adding a diode
2.11. Short circuit protection: Yes
3. Function Description:
3.1. The keys
"SELECT" key: press short to switch between voltage, current, power and wheel display; Long press -- to enter or exit correction mode;
"ON/OFF" key: short press -- to control the opening or closing of the output end; Hold down: Set the default power-on output to OFF or ON. Hold down for more than 3s to release. ON indicates that there is default output for each power-on, and OFF indicates that there is default output for each power-on.
3.2. Potentiometer knob
Current regulation potentiometer CC, clockwise rotation, can increase the limit current value, when the load current reaches the limit current, into the constant current state (note not adjust potentiometer can increase the output current, under constant voltage, output current depends on the load only, is based on the load change);
Maximum output current (constant current value) setting method: Switch to current display, directly short-circuit the output terminal to adjust THE CC potentiometer, the current value displayed is the maximum output current.
Voltage regulator potentiometer CV, clockwise rotation, can increase the output voltage.
3.3. Indicator light
CC -- Constant current indicator light, bright (red) when constant current;
ON -- Output status indicator (green);
3.4. Input/output ports
Input - left, USB male, microUSB, pad three ways to choose as input;
Output - On the right, the blue 2P terminal is the output.
4. Precision calibration method:
Output voltage calibration -- when the digital tube has been displaying the voltage, long press the "SELECT" key for more than 3 seconds to release, the digital tube flashes, short press the "SELECT" key once, the voltage value increases by one unit, short press the "ON/OFF" key voltage value decreases by one unit, when the output voltage is low, it may be necessary to press several times to see the value change of 0.1V; Hold down the "SELECT" key for more than 3 seconds to release and exit the calibration mode.
Output current calibration -- when the digital tube has been displaying the current, long press the "SELECT" key for more than 3 seconds to release, the digital tube flashes, short press the "SELECT" key once, the voltage value increases by one unit, short press the "ON/OFF" key voltage value decreases by one unit, may have to press several times to see the value change 0.01A; Hold down the "SELECT" key for more than 3 seconds to release and exit the calibration mode. Note: calibration is more accurate when current is greater than 1A; The display error is large when the output current is less than 0.05a, and may not be displayed when the output current is less than 10-40mA.
2.1. Input voltage: 4-13V (USB male, MicroUSB,TYEPE-C three input interfaces)
2.2. Output voltage: 1-30V (quick wiring terminal output, USB female output, note that the two are directly connected, carefully check the output voltage before inserting USB device!)
2.3. Output current: 0-2A (In constant voltage mode, the output current is self-adaptive according to the load size, not adjustable. If you set the limit current to 1A, then when the load current is greater than 1A, it will automatically enter the constant current mode, and the maximum output is 1A)
2.4 output power: less than 15W (when the output power is greater than 15W, the output will be automatically turned OFF and OPP will be displayed. After reducing the load power, press ON/OFF to solve the problem). When the input current is too large, it may not work above 10W for a long time due to temperature protection.
Voltage display: resolution 0.01V, factory accuracy ±0.1V or so, no reserved customer self-calibration.
2.6. Current display: resolution 0.001a, range 0-2.2a, factory accuracy ± 0.05a, no reserved customer self-calibration.
2.7. Power display: 0.00W-15.0W
2.8. Temperature protection: When the power component temperature is higher than 100℃, enter OTP protection. After reducing the load power, press the ON/OFF button to solve the problem (The power within 10W will not enter OT protection for a long time. When the input current is greater than 3A, it may enter overtemperature protection for a long time.
2.9. Working current: about 30mA
2.10. Anti-charging: Yes, it can be directly connected to the battery for charging without adding a diode
2.11. Short circuit protection: Yes
