Socay Metal Oxide Varistor 20D561K Surge Protection for Street Lamps Power Outputs
Street lamps, which have become a household name, are high-power, low energy-saving lighting that brings a lot of convenience to people's lives. Because it is directly connected to the city power grid, so the power supply is generally 220V AC, in the actual use process, the power grid will be due to a variety of factors and cause an instantaneous high-voltage fluctuations, as well as in thunderstorms, the power supply will be subjected to the lightning damage, these over-voltage acts will bring extreme damage to the power supply of the street lamp power supply. Therefore, the street lamp power surge protection has been urgent.
SOCAY Electronics recommended 20D561K varistor, the device uses DIP package, easy to weld, surge tolerance capacity is high, surge current up to 6.5KA, and leaves some margin, low leakage current. For AC220V power output port has a better surge protection.
Highly adaptable to the environment, with an operating temperature range of -40℃ to +85℃.
20D561K Varistor Features:
Maximum operating voltage VAC/VDC: 350V/460V
Varistor Voltage(@V1mA): 504~616V
Surge Current(@8/20μS): 6500A
Maximum Energy (@10/1000μS): 220J
Application of 20D561K Varistor:
Power supply for street lamps
Adapter
