Not working properly

For AC 60Hz/50Hz Dimmer/SSR Controller Board

I have been unable to get this board working properly in either PWM or voltage mode. I've tried various PWM frequencies with no change. Seems to go from off to barely on, then full power. Maybe not detecting 50hz AC properly? Will try to adjust the provided ATTiny code when I find a programmer and see if I can get it working.

Hi Brad,

I'd love to hear if you got this straightened out. I'm willing to work with you to find a solution.

Cheers.

Well designed product that meets its main use case

For AC 60Hz/50Hz Dimmer/SSR Controller Board

Well built product that works exactly as described on simple loads such as lights and is likely to work on any load proven to be compatible with this type of pwm.

I did not have success with my single phase large induction motor (1.5kw) pumping water at low speeds but that was 100% down to the induction motor which is specifically designed to work on a full sine wave @50Hz. I achieved some power control in a small range near full power though.

Very happy with my purchase.

Probably my fault for not checking first...

For AC 60Hz/50Hz Dimmer/SSR Controller Board

Three years later finally getting around to using it, but the active range of PWM makes it useless for what I wanted to do. In "voltage" mode it will pulse the motor noticeably while PWM just does nothing for me--likely related to using a 3.3V micro and not trying to do voltage translation. But not much point if I'm only going to get the same range out of this that I get from a cheap controller from Amazon.

Thank you for the honest review. I've made a change to the PWM detection function to allow for a wider range of frequencies and works at 3.3V. Some motors are okay with a chopped wave, but others need a VFD.

Really nice

For AC 60Hz/50Hz Dimmer/SSR Controller Board

Work at is supposed to. very nice little board and we use it to change speed of an AC motor in both 110-120v AC and 220-240v AC. It works fine and does exactly what we were looking for.

Thank you!
