Anmbest Constant Current Constant Voltage Buck Boost Converter Module DC 5.5-30V to DC 0.5-30V Adjustable CC CV Step UP Down Voltage Regulator 4A 50W Power Supply Module with LCD Display

It is a type of DC to DC converter and it has a magnitude of output voltage. It may be more or less than equal to the input voltage magnitude. The buck boost converter is equal to the fly back circuit and single inductor is used in the place of the transformer. There are two types of converters in the buck boost converter that are buck converter and the other one is boost converter. These converters can produce the range of output voltage than the input voltage. The input voltages are step up/down to some level of more than or less than the input voltage. Technical Specifications: Input voltage: 5.5-30V Output voltage: 0.5-30V Output current: long-term stable work in 3A, max 4A Output power: 35W natural cooling, heat dissipation to enhance 50W Voltage display resolution: 0.05V Current display resolution: 0.005A Conversion efficiency: about 88% Input reverse protection: Yes Output anti-intrusion: Yes Short circuit protection: yes Working frequency: 180KHZ Size: 66 * 48 * 21mm How to use: Used as an ordinary buck-boost module with over-current protection capability 1 Adjust the CV constant voltage potentiometer so that the output voltage reaches the voltage you want. 2 Measure the output short-circuit current with 10A current meter (connect the two test leads directly to the output end), and adjust the CC constant current potentiometer to make the output current reach the preset over-current protection value. (For example, if the current value displayed by the multimeter is 2A, the maximum current will only reach 2A when you use the module. When the current reaches 2A, the red constant voltage and constant current LED is on, otherwise the LED is off) Caution: When using in this state, there will be a voltage drop of 0 ~ 0.2V due to the current sampling resistor at the output. At the same time, the input and output leads will have a certain linear voltage drop.
