Adjustable Constant Voltage Constant Current Liquid Crystal LCD Multi-Display, PCB – TPU

Adjustable Constant Voltage Constant Current Liquid Crystal LCD Multi-Display, PCB – TPU.

Key Features:

• Input voltage: 6.5-36V (the input voltage is lower than 6.5V, the current accuracy is inaccurate, and the LCD display is abnormal if it is lower than 5.5V)
• Output voltage: 1.2-32V, the default output is 5V step-down type, the output voltage can only be lower than the input voltage, and the voltage difference is...
• Output current: It can work stably at 3.5A for a long time, and it can reach about 4.5A with fan enhanced heat dissipation (adjustable limit current can...
• Output power: natural heat dissipation 50W (within 3.5A), plus fan to enhance heat dissipation 75W
• Voltage display: resolution 0.05V, range 1.2-32V
• Current display: resolution 0.005A, range 0-4.5A
• Conversion efficiency: about 94%, depending on the voltage difference and current efficiency
• Working current: about 30mA
• Input reverse polarity protection: yes
• Anti-backflow at the output: no (if charging the battery, first power on the module and then connect the battery, and ensure that the battery voltage is...
• Short circuit protection: yes
• Size: about 70.5x48.4x28mm
• Weight: about 65g
• Features:
• Crystal shell, beautiful design, good touch texture of buttons, and output voltage set by button
• The button can control the output to turn off and on, and can set the power-on default to ON or OFF
• LCD can display input and output voltage, output current and output power
• The input terminal is protected against reverse connection, and the reverse connection will not burn
• High efficiency, high current, low heat generation, constant current value can be adjusted around 0-4.5A, suitable for office power supply, high-power LED...
• Function Description:
• There are IN/OUT and ON/OFF buttons on the left side of the module: the IN/OUT button switches the display of input voltage and output voltage, long press...
• There are +/- two buttons on the right side of the module: + button press the output voltage to increase 0.05V, long press to continuously increase, and...
• ADJ-I is the current setting potentiometer. Turn clockwise to increase the set current. When the load current reaches the set current, it enters the...
• Instructions:
• Use as an ordinary step-down module with overcurrent protection capability
• - Press the button to set the output voltage to the desired voltage value
• - Rotate the ADJ-I current adjustment potentiometer counterclockwise to the end, then measure the output short-circuit current with the 10A current range of...
• Use as a battery charger
• - The module without constant current function cannot be used to charge the battery. Because the voltage difference between the exhausted battery and the...
• - Determine the float voltage and charging current of the battery to be recharged; (if the lithium battery parameter is 3.7V/2200mAh, then the float voltage...
• - Under no-load conditions, the output voltage of the button reaches the floating charge voltage; (if charging a 3.7V lithium battery, adjust the output...
• - First turn the ADJ-I current adjustment potentiometer counterclockwise to the end, then measure the output short-circuit current with the 10A current...
• - Connect the battery and charge (when setting: no battery is connected to the output terminal)
• Used as a high-power LED constant current driver module
• - Determine the operating current and operating voltage needed to drive the LED
• - Under no-load conditions, press the button to set the output voltage to reach the LED working voltage
• - First turn the ADJ-I current adjustment potentiometer counterclockwise to the end, then measure the output short-circuit current with the 10A current...
• - Connect the LED, test the machine (when setting: output no-load, do not connect the LED light)
• Precautions:
• It is forbidden to short-circuit the input IN- of the module with the output OUT-, otherwise the constant current function will fail
• Make sure that the power of the power supply is always greater than the power required by the output load. When the module is seriously hot, please reduce...
