3>. Input voltage: DC 4-32V(limit 35V) please keep the voltage margin.
4>. Output voltage: DC 1.2-32V continuously adjustable (If the output voltage is always unchanged by turning after the power is energized on the module, you can turn the voltage potentiometer for more than 15 times anticlockwise.
6>. Output current: 0-12A (Temperature not more than 60 degrees for output less than 8A for a long time. Reduce output current when environmental temperature is high.)
7>. Output constant current range: 0-12A
8>. Working temperature: -40 to +85 Celsius
9>. Working frequency: 150KHz
10>. Conversion efficiency: up to 98% (efficiency is related to input, output voltage, current, differential voltage)
11>. Short circuit protection: yes (The limited current is current constant current value)
12>. Input reverse protection: no (if you need to series a diode at input)
12>. Output anti-retrofit protection: no (if you need to series a diode in the output string;please add the anti-diode between the output of the module and the battery when used as charger, otherwise the module will be damaged.)
1>.Please don't connect GND from input and output together during use.It will cause module current sampling resistance is the bypass, so that the module can't adjust output current.Module will be damaged if connect to high current load in this situation.
2>.If the output voltage of the module cannot be adjusted, please turn the CV potentiometer clockwise for more than 20 turns before using the module to adjust the voltage normally. Because the module leaves the factory, the default output voltage is around 17V.
1>.Used as a normal buck module with over-current protection capability;
2>.Used as charger for Lithium battery, battery, nickel-cadmium nickel-hydrogen battery.
3>.Used in solar panels, wind turbines, etc.
4>.Used as High-power LED constant current drive module.
1>.DIY is a regulated power supply with constant current function. It is not afraid of short circuit during use and can protect the load.
2>.Power your electronic devices.
3>.Charge various batteries, set the charging voltage and charging current according to the battery with different voltage and capacity.
4>.Using solar panels to power a variety of batteries, with a constant current function, to prevent battery overcharge, effectively protect the battery.
5>.Drive high-power LED, free to series and parallel combination.
6>.As a car power supply, power your mobile phone, laptop or a variety of digital products.
Method of setting voltage and current:
1>. Set Output voltage: according to the floating charge voltage value of the battery you want to charge, or the voltage value of the LED after series and parallel, adjust the constant voltage potentiometer (CV), set the output voltage to the required voltage.(without load)
2>. Set Constant current value: turn the CC potentiometer around 20 times counterclockwise, short-circuit output with multimeter at 20A grade, and adjust the CC potentiometer to make the current value to meet your require.
NOTE: The voltage need to be set more than 1.2V when set constant current.Otherwise the constant current function will fail.
