Output voltage: 0.5-30 V
Input voltage: 4-13 V (when using the pad input, pay attention to the positive and negative poles, DO NOT connect the AC power)
Output current: 0-2 a (the output current in constant voltage mode depending on the size of the load is adaptable, it is not adjustable.) If you set the limit current to 1 A, then the load current is greater than 1 A , the constant current mode 1A will be entered automatically)
Output power: less than 15 W (when the output power is greater than 15 W, the output is automatically turned off and the operation is displayed). After reducing the load power, press the on / off button to fix it). When the input current is too large, it can be turned off early due to temperature protection. Voltage display: Resolution 0.1 V, factory accuracy ± 0.1 V plus or minus (can be corrected manually after comparing with the standard voltmeter)
Current screen: Resolution 0.01A, range 0-2.2A, factory accuracy ± 0. 05A; the display error is greater when the output current is less than A, a small current can not be displayed within 10-40 mA (it can be corrected manually, the calibration of the output current is more accurate when it is greater than 1 A, and calibration is not recommended for small currents.)
Temperature protection: when the temperature of the power component is higher than 100 ° C, enter the OT protection, reduce the load power, press the on / off button to solve it (the power will not introduce the OT protection for an operation to long term in 10 W, when the input current is greater than 3A, You can introduce protection against overtemperature when it works for a long time, even if it does not reach 15 W)
Operating current: approximately 30 mA
Description of the function:
"Select" button: short pressure switch between voltage, current, power, wheel display; Long press or exit calibration mode;
"On / off button button: short pressure control of the output end that turns on or off; long pressure: set the default power on to be off or on, press to release more than 3 s, it will be displayed for each power-by default there is an output, and the screen off means there is no default output each time turn on the energy.
The current adjustment potentiometer CC turns clockwise to increase the current limit value. When the charging current reaches the limit current, it enters the constant current state (keep in mind that the output current can be increased without adjusting the potentiometer.) At constant voltage, the output current only depends on the load, varies according to load);
Maximum output current (constant current value) Configuration method: Switch to current screen, shorten directly the output terminal to adjust the DC potentiometer.
The CV voltage adjustment potentiometer rotates clockwise to increase the output voltage.
The indicator lights
CC - constant current indicator light, bright when the constant current (red);
Status indicator on the output (green);
