PWM to 0-12VDC using Arduino

[Basss]

Hello guys,

I have some equipment which needs a control voltage to select the speed. At this time I use an Arduino in combination with a PWM to 0-10V converter as seen below.
It works pefect, except I can't reach full speed because the device expects a control voltage from around 2-12V.




Does anyone know a solution to solve this?

Kind regards,

Bas

1) What is the supply voltage range for the gadget you are showing? Do you have a data sheet or specs?

It could be as simple as increasing the supply voltage a couple of volts.

I only have the following information from ebay

PWM 1-10V Digital to Analog Signal Tranformer Module for PLC Signal Interface Switch

Features:
- Tranform PWM signal to 0-10V analog signal, used on PLC or other industrial control board signal interface switch
- PWM signal receive frequency range: 1-3KHZ
- PWM signal receive level range: 5V level(If 12V/24V, need an resistor to limit current, 12V 330-560ohm, 24V 1.5-2.7K ohm
- Voltage Input: 12V/12V-28V

I only have tried it with 12V supply, but if I read the info the max output will be 10V even if it's 28V.


Regards,

Bas

I'm newbie with electronics but I did some projects with Arduino. I may be wrong but seems to me you need a transistor. Using PWM to the base you got the current you want. Please someone tell me if I'm wrong.

I recommend letting the uC drive a power MOSFET driver IC
(best, through some buffering that can break any ground
loops) which can be had at multiple amps of output drive
and take 12V easily.
