Description:

• High Power DC to DC Boost Converter: This module with a function of constant voltage and constant current. It can be used to provide charge for electronic devices. Suitable for voltage stabilization of solar panels, charging of batteries, lithium batteries, etc

• Wide Input Voltage and Output Voltage: Input voltage: 10-36V; output voltage:12-80V. The output current can be adjusted(Max 20A). ultra-low input and output voltage difference. When the current > 18A, please strengthen the heat dissipation

• With Overcurrent and Short Circuit Protection: Double short-circuit protection (input 20A fuse); with output anti-reverse flood protection, no need to add anti-reverse diode when charging.Note: There is no reverse connection protection, if you have this need, please connect a diode in series with the input

• Large Heat Sink: Large heat sink design (85mm62mm64mm), and it has been processed with black oxidation (black oxidation has better heat dissipation). Which can prolong the service life of the module and make the conversion efficiency of the module higher

• Widely Application: High-power LED constant current drive, Lithium battery charging, Ni-Cd or Ni-MH battery charging, Solar panels, Wind Turbines, and so on

Note:

• The output voltage must be greater than the input voltage by 3V or more.
• It is a DC power module,So it can not connect to AC power.
• Please add a radiator or fan if the temperature is higher than 65℃.
• Please make sure input power is more than load power.
• Please step down output power if module is hot.

Adjust output voltage and current

• Rotary CV potentiometer to adjust output voltage. Increase the output voltage value by clockwise.Decrease output voltage value by counterclockwise.

• Rotate CC potentiometer counterclockwise more than 30 turns at first. It is used to set the initial current to the minimum at first.

• Connect LED lamp or other equipment. (User must ensure that the battery is discharged at first if need connect the battery to charge. Otherwise the set current value will be very small and resulting in a slow charging).

• Rotate CC constant current potentiometer to set output current according to required
