REES52 Buck Boost Converter Display, Buck-Boost Board DC 5.5-30V 12v to DC 0.5-30V 5v 24v Adjustable Constant Current Voltage Step UP Down Voltage Regulator 4A 35W Power Supply Module

Features

• Buck-boost converter input voltage range is DC 5.5-30V; output voltage range is DC 0.5-30V, can be arbitrary adjustable; output current range is 0-3A, can be arbitrary adjustable, if enhance heat dissipation, it can reach 4A; max output power is 35W, if enhance dissipation, it can reach 50W.
• LCD Display: the voltage regulator module is designed with LCD, can display input and output voltage, output current and output power; voltage display resolution is 0.05V, current display resolution is 0.005A.
• Safe Protection: the volt transformer board is with reverse connection protection at input terminal, reverse connection will not burn; stop the current from feeding back protection at output terminal; short circuit protection.
• Button Control: button control output voltage ON / OFF status, and you can set the default output state is ON or OFF of the next time power-on.
• Application: the switching power supply can be used as an ordinary buck-boost module with over-current protection; used as a battery charger; used as a high-power LED constant current driver module.
