LED controller, is to control the switch of each position in the LED light circuit??by chip processing. The controller according to the pre-set procedures and then control the driver circuit to make the LED array regular light, so as to display the text or graphics.
However, in the actual use of the process, the LED controller is easy in the power supply is not stable when subjected to peak voltage or the introduction of external surge interference, if not protected, it will damage the LED controller.

Socay lectronic launched a surge protector MOV 14D511K and protection scheme, ?as shown?in the figure below:

Surge Protector?MOV 14D511K, with a voltage of 510V and a maximum surge current of 4500A, operates at temperatures ranging from -40°C to 85°C. It is made of zinc oxide, sintered with a variety of trace metal oxides, and encapsulated in epoxy resin. High surge absorption capacity and high stability, can meet the LED controller surge protection.

Surge Protector MOV 14D511K is widely used in LED controllers, lightning protectors, household products, power meters, communication products and switching power supplies.

Socay 14D511K can replace the models of MOV-14D511K, FTR14D511K, VDR-14D511K, etc. from other manufacturers.
