Two-channel PWM dimmer – Doubledimmer

Part no.: ART13273
The Doubledimmer device is a two-channel adjustable dimmer for independent control of two PWM channels. PWM is set on the dimmer with a high quality rotary potentiometers. One channel can be used, for example, to control the signaling lights and the other to set the dashboard backlight. The controllability of the channels is in the range OFF, 1 ÷ 100%. PWM dimmer is + type (switches VCC potential). Replaceable front label.

The assembly of the product is carried out by building it into the panel. First, the electrical signals are connected to the terminal board of the device, and we can proceed to the mechanical installation. All you need to do is drill 3 holes for potentiometers and an M4 fixing screw in the dashboard. The device is inserted from the back side of the dashboard and fixed with an M4 screw and nut. Then put on a label, to screw the potentiometer nuts and the knobs of the potentiometers are mounted.
