Topic: Arduino Uno gives me 5 Volt PWM. Need 10 Volt PWM. (Read 467 times) previous topic - next topic

Greetings,

I have succesfully installed, configured and experimented with an Arduino Uno.

My goal is to regulate a Mean Well HLG-185H-C1400B led power supply using either a PWM signal of 10 Volt or a DC voltage ranging from 0 V to 10V.

My Uno now produces a PWM signal from which the duty level I can control from my schetch.

However, The Mean Well device needs a 10 Volt PWM signal.

Any suggestions on how to boost a 5 Volt PWM signal to a 10 Volt PWM signal?

Hope te hear, Aad.

A N channel logic level MOSFET could translate a 5V PWM signal to 10V PWM (although the signal would be inverted).

You don't need a 10volt PWM signal for those LED drivers.
There is already a 10volt supply buildin, that only has to be PWM-ed/switched with a transistor or opto coupler.
I would prefer an opto coupler.
Collector to DIM+
Emitter to DIM-
Opto LED with ~330ohm current limiting resistor driven by an Arduino PWM pin.
