High voltage LED product controller:
High voltage LED product design voltage is AC/DC 220V voltage, each loop LED number 36-48 series, each loop current below 20mA, there are two current limiting ways, one is resistance current limiting, this way resistance power consumption is larger, it is recommended to use every 4 LED series connected to a 1/4W metal mode resistor, uniform distribution of heat dissipation, This connection is the most stable and reliable; The other is the resistance capacitor in series current limiting, this connection most of the voltage drop on the capacitor, resistance power consumption is small, can only be used in the stable long bright state, if the flashing capacitor energy storage, but double the voltage, LED is easy to damage. All the use of controller LED must use resistance current limiting mode, LED generally one meter per loop, power 5W, three-color power per meter 15W. Commonly used gradient controller NE112K controls 1200W DC and NE103D AC load 4500W DC load 1500W. If there are many flashing units of the lamp tube, NE112K is used; if only the whole flashing is needed, NE103D is used. If you use gradient mode, pay attention to load matching, neon lights and LED light distribution characteristics are not the same, the same loop can not be mixed with different types of load.
