A unique feature of the system is the ability to determine the current time based on the history of switching on and off. The start time offull or partial reduction of power and its duration are set with an accuracy of 30 minutes. Switching in luminaires supplied from a single line takes place simultaneously with second precision. APC-LED is designed for control LED power supplies with integrated intensity reduction system (1 ~ 10 Vdc interface is used, changing fulfilment of PWM signal or resistance).APC-LED allows a temporary reduction in light stream output of different types LED luminaires. The system has two pre-programmed time intervals, which light output on two different levels is reduced. The user can reprogram the system so that it will change both the scope of both time intervals and the level of reduction. Programming is based on the use of an appropriate sequence of switching the power on and off. APC-LED PROG is used to program the APC-LED power reducing devices integrated in lighting fixtures. It enables to easily and simultaneously change the settings of all fixtures supplied from a single circuit with are fitted with APC-LED devices.
APC-LED may also be programmed via the CPAnet system.
