Buck Boost Converter DROK DCDC Buck Boost Converter Voltage Step Up Down Regulator CC CV 530V to 0530V Adjustable Power Supply Transformer Module

Parameters: Input voltage: DC 5~30V Output voltage: DC 0.5~30V Output current: 3A (Long-term stable work); 4A (enhance heat dissipation) Output power: 30W (natural heat dissipation); 50W (enhance heat dissipation). Conversion efficiency: Boost voltage 88~91%; Buck voltage 87~90%?varies by voltage difference and load? Working frequency: 180KHZ Board size: 68*29*21mm Using Manual? The defaulted output voltage is 12V and the default constant current value is 2A. Please adjust the output constant current value to avoid damaging the load. The taller multi-turn potentiometer is used for adjusting the output voltage. The shorter single turn potentiometer is used for adjusting the constant current value. If you need to increase voltage or current, please adjust the corresponding potentiometers clockwise. To decrease, turn the corresponding potentiometers counter-clockwise. Turn lights in full-charge?A red LED indicates constant current output. A blue LED indicates charging. A green LED indicates that the charging current is less than one-tenth the set value. Application: 1. Very suitable for the device of large input voltage range and constant output voltage, such as constant voltage battery, solar power generation, power module. 2. Input a constant voltage (such as mobile phone charger or storage battery charging) can get DC 0.5~30V adjustable power. Package Including: 1 X Auto Buck Boost Voltage Converter Module
