【One-year after-sale warranty】The PWM to voltage module converts PWM digital signals to 0 to 10V analog signals. It can be used to switch the signal interface of PLC or other industrial control board. Adjust the output voltage by adjusting the PWM duty cycle. The module is small in size and easy to apply in different places.003cbr003e.
Using MCU embedded technology. Easy to operate, can be fine-tuned by potentiometer.003cbr003e.
Select the PWM signal input level range by short circuit. The module is small, easy to carry and easy to use.003cbr003e.
(current greater than 100mA)，PWM signal receiving frequency range: 1KHZ-3KHZ.
When power on for the first time, it is best to do a calibration and debugging: find a signal with a 50% duty cycle and connect it to PWM and GND. Jumper caps set the corresponding voltage range. When the frequency is 1KHZ-3KHZ, use a multimeter to measure the two ports of VOUT and GND. At this time, the meter displays about 5V. Adjust the potentiometer on the board so that the multimeter displays 5.00v.003cbr003e.
DROK Voltage Boost Converter, DC 6-30V 5V Step Up to DC 7-32V 12V 24V 5A Adjustable Volt Regulator, LCD Power Supply Module Voltage Current Amp Display Transformer Circuit Board with Case
...rd is designed with a large clear digital LCD display on which shows both voltage and current value simultaneously. Which is easy to read and can help the user easily monitor the output voltage, then largely enjoy their DIY work..
General Application --- This voltage step up converter can be used as ordinary step-up module with over-current protection, constant current LED driver module.
Features --- Constant current/voltage mode.
Input reverse connection protection. You can find the PDF Instructions on this page -- Product information -- Product guides and documents -- User Manual [PDF]..
NOTE --- 1). Constant current adjustable means that CC mode only works when the actual load output current is greater than the setting one, otherwise it will work in a constant voltage state, not the current is adjusted to 2A, then it will become 2A for any load being connected. And if the CC value to be adjusted is small, adjust “ADJ-I” counterclockwise a few more times to change. 2). The case is packaged disassembly to avoid damage during transit. It needs to be manually installed..
