Description: PWM-to-voltage module can convert the digital PWM signal 0%-100% into an analog signal 0 ~ 10V. Can be used for industrial control panel or other signal interface switching, by adjusting the PWM duty cycle to regulate the output voltage. Adopts embedded microcontroller technology, easy to operate, you can fine-tune it through the potentiometer. Further increases the output voltage accuracy to within 1%, the input frequency is increased to 3KHZ, support PWM, duty cycle to voltage (via short resistor) and 5V/10V selection (via short resistor). Specification: Size: Approx. 33.14 x 33.02 mm/1.304 x 1.3 inches 5/10 short D/F -1KHz frequency to 0-5V (duty cycle at will) 5/10 open D/F -1KHz frequency to 0-10V (duty cycle at will) 5/10 short D/F short 0-100% duty cycle to 0-5V (frequency range 1Hz-3KHz) 5/10 open D/F short 0-100% duty cycle to 0-10V (frequency range 1Hz-3KHz) Supply voltage: 9V ~ 24V Signal input frequency range: 1Hz ~ 3KHz (amplitude 3.3V-5V) Signal input duty cycle range: 0 ~ 100% (amplitude 3.3V-5V) Output voltage: 0.00V ~ 5.00V/0.00V ~ 10.00V Error Tolerance: within 1%, linear conversion Wiring definition: 12V: Positive power connector (9V to 24V) GND: Power ground interface PWM: signal input (1-1KHz 0-100%) (amplitude 3.3V-5V) GND: signal input negative interface or ground OUT: Signal output interface (0.00V to 5.00V/0.00V to 10.00V) GND: Ground interface Note: When the output is from 0.00V to 10.00V, the power supply voltage must be more than 10 volts. Package Includes:(3 Pack) 1 Piece PWM to Voltage Converter Module Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
