This is a constant current PWM. This means that you will set it for the amperage you want your HHO system to draw. Then as temperature conditions change, and the system starts to draw more amps, the PWM will adjust automatically so you maintain the same current draw. You can find out more about how this works, in this article: What Is a PWM?
This unit is housed in an aluminum heat sink case. The case parts all have a clear annodized finish with blue lettering.
You can see more details about this product in the Installation Instructions.
What's in the Box?
20 Amp CCPWM This is the main unit
5 x #10 Ring Terminals: These are for connecting your 10 gauge wires to the PWM. You'll need 4. The 5th is an extra.
Size: The body of the PWM is 5-1/8" (W) x 4-1/2" (L) x 1-3/4" (H). The width dimension includes the mounting flanges on each side. The Length dimension does not include the terminal block (1/2") or the adjustment knob (about 3/4").
