The PlugBox ESS Light is an auxiliary unit for the activation of power supplies that have 1-10V control inputs, in order to engage a late-night circuit (night dimming) by means of a second phase (230VAC). Additionally, a second phase (control phase), linked to the luminaire, is connected to the PlugBox ESS Light To set the brightness of the luminaire, the 1-10V control input of the LED driver is steered by the PlugBox ESS Light such that the LED-current can be set in steps of 10%, from a low of 10% up to100%.
