24vdc outdoor IP67 lighting transformer power supply for led lights UL CLASS 2 certified
The output voltage of PWM led driver 24v led dimmer to 0V, the output current down to 0 accordingly , the brightness of the light is off (there is a switch), when we up the output voltage of led dimmer to 10V maximum, the output current will reach 100% of the led driver output, light brightness will be 100%. (Output voltage of led driver is constantly)
