Feature:
1. Beautiful design, good touch texture, button set output voltage.
2. The button can control the output switch to turn on and off, and can set the default power on to ON or OFF.
3. LCD can display input and output voltage, output current and output power.
4. Anti-backconnection protection of input terminal, backconnection will not burn up.
5. High efficiency over 93%, high current, low heat, output voltage 1.2-32V arbitrary adjustment, constant current value about 0-4.5A adjustment, suitable for office power supply, high-power LED constant current drive, lithium battery battery charging, etc.

Specification:
Input voltage: DC 6.5-36V (input voltage below 6.5V, current accuracy is not accurate, below 5.5V LCD display is not normal)
Output voltage: DC 1.2-32V
Output current: It can work stably at 3.5A for a long time, and can reach about 4.5A under enhanced heat dissipation (the maximum adjustable limiting current is about 4.2-4.5A).
Output Power: Natural Heat Dissipation 50W (less than 3.5A), Enhanced Heat Dissipation 75W
Voltage Display: Resolution 0.01V, Range 1.2-32V, Accuracy (±0.1V or so)
Current display: resolution 0.002A, range 0-4.5A or so, accuracy (±0.05A or so)
Conversion efficiency: about 94%
Working current: about 30 mA
Input Reverse Connection Protection: Yes
Output anti-backfilling: No (if the battery is charged, the module is first energized and then connected to the battery to ensure that the battery voltage is lower than the output voltage; if conditions permit, please connect the anti-backfilling diode in series with the output cathode)
Short circuit protection: Yes
Product size: 70.5*48.4*28mm/2.77*1.9*1.1\'\'
Packing weight: 70g

Functional Description:
1. On/OUT and ON/OFF buttons are on the left side of the module: IN/OUT buttons switch input voltage and output voltage display, long press can switch output current output power display; ON/OFF buttons control output ON or OFF, long press can set the default output state of next power-on is ON or OFF.
2. On the right side of the module, there are two buttons: \"+\" button can increase output voltage by 0.01V, long press can increase continuously, then long press can increase by 0.1V and 1V at a continuous slow pace; \"-\" button can decrease output voltage by 0.01V, long press can decrease continuously, and then long press can reduce by 0.1V and 1V at a continuous slow pace.
3. 2A DJ-I sets potentiometer for current, and rotates clockwise to increase the set current. When the load current reaches the set current, it enters the constant current state, and CC constant current indicator (red) lights up.
4. OUT indicator lamp is the output state indicator lamp, when the output voltage is on, otherwise it will go out; CHAR indicator lamp is charging indicator lamp, when charging, FULL indicator lamp is full indicator lamp, if the constant current value is 2A, charging current is below 0.2A, turn lamp, FULL indicator lamp is on, CHAR indicator lamp is off.

Warm Tips:
1. The module is DC to DC step-down module, which can\'t input AC power of voltage changer directly step-down. When charging the battery, make sure that the output terminal of the module is electrified first and then connected to the battery.
2. When full charged, the battery is pulled out first and then the module is cut off, so as to prevent the battery voltage from backfilling (it is better to connect a large current diode to the positive output of the module to prevent backfilling).

Note:
Please allow 1-3mm differs due to manual measurement.
Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
