Module working voltage: DC 12 v - 30 v.(power requirement: more than 100 mA)PWM signal receiving frequency range: 1 KHZ - 3 KHZ;PWM signal input level range:Fengfeng value of 4.5 V to 10 V level, jump needle at 5 V.The class level signal mainly for conventional industrial control CARDS (e.g., MACH3 boards), 5V CPU interface;Fengfeng value between 12 and 24 v level, jump needle at 24 v.The class level signal mainly for conventional PLC interface.PWM conversion range: 0% - 100% PWM conversion 0 to 10V Permissible error: 5%. VCC: work power 12 v - 30 v.GND: working power。PWM: input PWM signal positive pole.GND: the input signal is negative end.VOUT: 0 to 10 v output voltage.GND: output voltage.Instructions: after power on, there is no input signal, the output is 0 v.Electricity for the first time, it's best to do a calibration debugging: find a 50% duty cycle of the access to the PWM signal, GND, corresponding to the relative amplitude jump needle.Frequency in the 1 KHZ - 3 KHZ, VOUT is measured with a multimeter, GND two ports, the table displays at around 5 v, adjust the potentiometer on the board, make says in 5.00 v on the multimeter. The calibration is your pulse signal and the corresponding relation of the module.When the frequency changes, there may be offset, the corresponding relationship needs to be calibrated.Output voltage can be adjusted by adjusting the duty ratios.Package Includes:1x DollaTek PWM turn voltage module 0%-100%PWM turn to 0v-10V voltage ## Features - Easy to operate, can pass to fine-tuning potentiometer. - Through the short circuit choose PWM signal input level range. - Module is small, portable and easy to use. - MCU embedded technology. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DK51KXR | | Best Sellers Rank | 57,443 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 1 in Digital Signal Processors | | Guaranteed software updates until | unknown | | Manufacturer | DollaTek | | Package Dimensions | 15.5 x 9.8 x 1.5 cm; 10 g | ## Images ![DollaTek PWM turn voltage module 0%-100% PWM turn to 0V-10V voltage - Image 1](https://m.media-amazon.com/images/I/61gr8FRAgHL.jpg) ![DollaTek PWM turn voltage module 0%-100% PWM turn to 0V-10V voltage - Image 2](https://m.media-amazon.com/images/I/61zkr2txNbL.jpg) ![DollaTek PWM turn voltage module 0%-100% PWM turn to 0V-10V voltage - Image 3](https://m.media-amazon.com/images/I/61Dx3oHkbTL.jpg) ![DollaTek PWM turn voltage module 0%-100% PWM turn to 0V-10V voltage - Image 4](https://m.media-amazon.com/images/I/5144+2ZGz1L.jpg) ![DollaTek PWM turn voltage module 0%-100% PWM turn to 0V-10V voltage - Image 5](https://m.media-amazon.com/images/I/51ghJFLSuyL.jpg) ## Questions & Answers **Q: Can this be used with a 3.3v pwm signal like the output from a raspberry pi?** A: I have recently checked these modules and they do work with 3.3V logic providing that the PWM pulse width is adequately long to trigger the opto-coupler. I had three of 8 ordered come with with short circuit voltage regulators though. ( I removed the reg and supplied at 12.00V DC instead and they worked OK. The circuit is not very linear when used with pulse widths as intended ( ie to match the two stage low pass filter before the op amp ) due partly to the excessive capacitance (C5) connected across the opto coupler ( C5) input and also the op-to coupler response. It works better with this IC removed ( easy to do as its a PTH IC) but to get less than 1 bit error at 8 bit conversion major mods are required to the circuit including removal of the opto-coupler and a 2:1 gain increase in the op amp stage to give a nominal 0-5.3V output for 3.3V logic pulses When modified it can achieve better than 0.5 lsb linearity at 8 bit with an analogue output update rate of approx 50Hz. Stability and drift will depend on the stability of the 3.3V pulse train but if thats stable it can provide a cost effective and accurate DAC. ## Frequently Bought Together - DollaTek PWM turn voltage module 0%-100% PWM turn to 0V-10V voltage - 1-3KHZ 0-10V PWM-to- Voltage Module, Digital Voltage Converter, PWM Digital to Analog Converter Module - DollaTek PWM Voltage Converter Module, 0V to 5V / 0V to 10V, 0-100% PWM Signal, Plastic, PCB Mount --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/112096343-dollatek-pwm-turn-voltage-module-0-100-pwm-turn-to](https://www.desertcart.tn/products/112096343-dollatek-pwm-turn-voltage-module-0-100-pwm-turn-to) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-31*
