The Role Of The Lighting Controller

- May 31, 2019-

1. Control function

The flexible programmable control function can control the step-down voltage limit and the switch lamp time can be set arbitrarily. Control mode is sometimes controlled, light control, manual control, remote control of the upper computer and automatic control according to the latitude and longitude of the place of use. Soft start, soft transition, soft shut-off function, prevent over-voltage and cold start large current impact on the luminaire, greatly reducing the damage rate of the luminaire. For sodium lamps, mercury lamps and other lamps with adjustable full-pressure preheating start-up time, the lamps can be fully preheated and smoothly transition to normal working conditions. It can realize all-night light and midnight light control, and it has the function of step-down and current adjustment in the middle of the night, and the energy-saving effect is more ideal. The perfect restart function can automatically re-ignite the luminaire when the load is faulty and the external power supply is over. Control mode is sometimes controlled, light control, manual control, remote control of the upper computer and automatic control of latitude and longitude according to the place of use (optional). The three-phase switch lamp time and output voltage can be adjusted independently, and can be connected to unbalanced and different types of loads. Programmable service mode for easy access to lighting system maintenance, maintenance and lamp replacement. A set of clock-controlled normally open contacts is reserved for special control. The contact capacity is 7A/250VAC.


2. Protection

Perfect lightning protection, overvoltage, overheat protection. Three-phase independent overload protection, alarm prompt. Fault alarm automatic bypass function, and award fault signal upload. Emergency lighting automatic switching function. In some special occasions, uninterrupted lighting is required. When the main lighting circuit fails and the main lighting circuit is automatically switched to the DC emergency power supply system, the controller automatically detects the change and keeps the lighting uninterrupted. Power outage data protection. When the system is powered off, the set parameters are not lost, and the clock can still operate normally and accurately.
