Lumento X4. 4-channel constant voltage PWM dimmer  for DV LED loads

Lumento X4. 4-channel constant voltage PWM dimmer for DV LED loads

Product code: ZN1DIRGBX4
LED lighting controller. 4 channels (RGBW). Lumento X4 is a 4 channel (RGBW) controller of up to 2.5A / channel, designed for 12 to 24 V LED technology. Channel dimming is based on varying the voltage by pulse width modulation (PWM). Lumento X4 has a test push button in order to check the correct operation of the 4 channels. It is highly configurable and allows easy control of all the channels together or each channel independently.
