Boost Buck Converter DROK DC 5 5 30V to 0 5 30V 5V 12V 24V Adjustable Power Supply Regulator Module 4A 35W High Power Voltage Step Up Down Converter Board with Case LCD Display

DROK DC-DC Step Up/Down Voltage Regulator Board Parameter: Input voltage: DC 5.5-30V (If input voltage lower than 5V, it can achieve buck/boost, but the measured voltage and current value will be inaccurate. When input voltage lower than 4.7V, it will trigger under-voltage protection). Output voltage: DC 0.5-30V Output current: 4A for long-term working Output power: 35W Voltage display resolution: 0.01V Voltage accuracy: 1% Current display resolution: 0.001A Current accuracy: 1% Conversion efficiency: about 88% Soft start: YES (maybe invalid when starting with high-power load) Working frequency: 180kHz Size: 72*59*32mm Protection: Soft start; Input reverse connection protection Output anti-backflow protection Short-circuit protection Over-current protection Over-power protection Over-temperature protection Buttons: IN/OUT button: Short press: switch to display input voltage/output voltage/module temperature. Long press: switch to display output current/output power. ON/OFF button: Short press: control output ON/OFF. Long press: set output default ON/OFF when powered on. Package Included: 1x Buck Boost Board
