Qianson DC 6V-24V 12V 3A Solar Charge Controller Battery Charging Charger Backflow Prevention Volt Amp Adjustable CC CV Power Module
Qianson DC 6V-24V 12V 3A Solar Charge Controller Battery Charging Charger Backflow Prevention Volt Amp Adjustable CC CV Power Module Features
- Automotive Lighting LED driver, constant current 3 series range 0.1-3A compatible with the common 1-30W LED current. Both domestic and 1w LED is now popular CREE T6 can easily drive. Conversion efficiency up to 98%!
- Small stepless dimming lamp, with a large potentiometer replaced board precision adjustable resistors. Setting LED operating current range, it can easily achieve stepless dimming lamp. Compared to PWM dimming mode, a light source is more stable, flicker-free!
- With MAX1879 achieve accurate flow control, stepless adjustment MAX1879 charge current, fast charge slow charge arbitrary!
- Lithium charge voltage setting: Lithium battery charging voltage requirements were very strict, overcharging will cause the battery capacity decay rapidly and shorten battery life. Without knowing the battery voltage, it is recommended to charge sheet output voltage is set at 4.2V (two lithium battery: 8.4V). Charge single-cell input voltage ≥7.7V, charge two battery input voltage ≥11.9V.
- Lithium charge current setting: Different lithium batteries need to set the charging current is different, generally can be 10% of the battery capacity - 100% of the set. Trickle charge can extend battery life, the battery charge is more full. The charge sheet output current at 50mA - adjustment between 2000mA.
