The improvement of dimming controller of dimmable led downlight

 

Lighting controller to the line dimming or secondary side of the dimming way to work. The simple line dimming the forefront of SCR controller. This is the most commonly used lighting control, but unfortunately, the use of SCR controller when the dimming of the dimmable led downlight produce a large number of problems. Flexible programmable control functions can be controlled step-down pressure limiting magnitude, the light switch time arbitrarily set. Control mode and sometimes control, light control, manual control, PC remote control and location according to latitude and longitude of automatic control. Soft start, soft transition, the soft-off function to prevent the impact of voltage and cold start current of the lamps, significantly reducing the damage rate of the lamps. Preheat start time, dimmable led downlight, mercury lamps with adjustable lighting can be more fully warm-up, a smooth transition to the normal working condition.

 

To achieve control of the whole dimmable led downlight, and there late at night and then step-down to adjust the flow function, the energy saving effect is more ideal. The perfect re-start function when the load fault, the end of the external power supply failure, automatically re-lit lamps. Control mode and sometimes control, light control, manual control, PC remote control previously used on led high bay and automatic control according to the latitude and longitude of the place of use (optional). Three-phase light switch time and the output voltage can be adjusted independently, which can be accessed imbalances and different types of load. Programmable mode of maintenance, ease of maintenance of lighting systems, maintenance and lamp replacement. Reserved for the normally open contacts of a group of control by the clock in order to achieve a special control. Contact capacity 7A/250VAC.
