Buck Boost Voltage Regulator, DC 6-30V to DC 0.5-30V 5V 12V 24V Adjustable Voltage Converter, 4A 60W Power Supply Step Up Down Transformer Board Module with USB Port Case LCD Display Volt Am

Parameter: Input
voltage: DC
6-30V; output voltage: DC 0.5 -30V; output current: 4A maximum, adjustable, recommended for use within 3A; output power: 60W maximum, recommended for use within 50W. This product is intended solely for DC-DC loads that do not incorporate computers or laptops.
Easy-to-Read LCD Display: The buck-boost board features a large, clear digital LCD display that shows voltage and current values simultaneously, making it easy to monitor the output voltage during DIY projects.
Application: This voltage step-up and step-down module can be used as a boost-buck converter module with over-current protection, a battery charger, or a high-power LED constant-current driver module.
Features: Constant-current/constant-voltage modes; voltage calibration; USB output; protective case; short-circuit protection; over-temperature protection; and input reverse-connection protection.
Note:
1. Adjustable constant-current mode works only when the actual load output current is greater than the set value. Otherwise, the module operates in constant-voltage mode. Setting the current to 2A does not make the output 2A for any connected load. If the CC value is set low, turn ADJ-I counterclockwise a few more times for adjustment.
2. The case is packaged disassembled to help prevent damage during transit and requires manual installation
