Does this draw any power when switched off?

I guess it will draw few mA for 555 timer.

does this controller work in forward/reverse mode?

no, not specifically. For most types of DC motors, you could use an appropriately rated switch (DPDT rated for more than the amperage of the motor) to reverse polarity, and thus direction easily enough...

will this work as a dimmer for LEDs?

If your leds are 12V DC led strip up to 5 amps, then yes you can use it as a dimmer. In fact, there is a LED on the board for indication and its brightness shows the PWM duty cycle.

Awesome motor speed controllers

Both switches functioned flawlessly out of the packaging. Installation was a breeze with a clearly marked terminal block. Speed control is precise and smooth. I guess that knob colors are random; mine were green.

Works good

Not true pwm generators. They are specific frequency, but change duty cycle. So far so good. Cheap enough to replace if they quit.

Hmm suspicious

I installed this on leds strip white lights. Everything I have done is correct, as in power from battery ---->to the fuse----> to the on/off switch and finally to this voltage step down or up. The lights lights up and dim down...... but with NO power to it and deactivating the on/off switch, somehow it still sends power to the lights. If i turn up the voltage when switch is OFF it finally shuts down like it should. Its a mystery

Exactly what I wanted!

This little gem works as advertised. I use it for a custom n-scale turntable setup and it's perfect. Very easy to control.

Lacks low end power

I'm using one of these to replace a burned out PWM on a magnetic lab stirrer to mix hobby paints. It does great at high speeds, but really struggles at low speed. Which kinda sucks because higher speed can introduce air & create almost a frothy paint.Anyway, easy to use & does the job. Unless you're looking for low end (slow) speed. I plan to try a lower powered power supply & see if that helps. I'll update when I try it.
