CC CV DC 6.5-36V to 1.2-32V 5A 75W Step Down Buck Converter Power Supply Module Voltage Regulator Transformer with Case Heatsink
The step-down DC-DC constant voltage constant current power supply module with liquid crystal displays the input and output voltage, output current and output power; the transparent acrylic board shell is beautiful and generous, and the button sets the output voltage, eliminating the trouble of adjusting with a flat-blade screwdriver. Suitable for office power supply, high power LED constant current drive, lithium battery battery charging, etc.
Input voltage: 6.5-36V (input voltage is lower than 6.5V, current accuracy is not accurate, LCD display below 5.5V is not normal)
Output voltage: 1.2-32V, factory default output 5V.
Output current: It can work stably for 3.5A for a long time, and can reach 4.5A with enhanced heat dissipation (adjustable current limit is about 4.2-4.5A)
Output power: natural heat dissipation 50W (within 3.5A), enhanced heat dissipation 75W
Voltage display: resolution 0.05V, range 1.2-32V, accuracy ± 0.1V (for customers with strict precision requirements)
Current display: resolution 0.005A, range 0-4.5A, accuracy ±0.05A (for customers with strict precision requirements)
Conversion efficiency: about 94%
Working current: about 30mA
Input reverse connection protection: Yes
Output anti-backflow: None (If charging the battery, first power on the module and then connect the battery, and ensure that the battery voltage is lower than the output voltage; after charging, first pull the battery and then power off the module. If there are conditions, please connect the output positively. Current anti-backflow diode
Short circuit protection: Yes
ADJ-I is a current setting potentiometer. It rotates clockwise to increase the set current. When the load current reaches the set current, it enters the constant current state, and the CC constant current indicator (red) lights up. The OUT indicator is the output status indicator. When the output has voltage, it will be on, otherwise it will be off. The CHAR indicator is the charging indicator. When charging, the FULL indicator is full. If the constant current value is 2A, the charging current is set. When the voltage reaches 0.2A or less, the lamp will turn on, the FULL indicator will be on, and the CHAR indicator will be off.
There are +, - two buttons on the right side of the module: + button presses the output voltage to increase 0.05V, long press can be continuously increased and then long press can increase the continuous slow step by 0.1V, 1V; - press the button to reduce the output voltage by 0.05V Long press can be continuously reduced, and long press can reduce the continuous slow step by 0.1V, 1V.
