Surge Protector abbreviated as SPD, also known as Surge Protector, Power Lightning Protector, is suitable for 48Vac-1000Vac low-voltage AC power distribution system and 5Vdc-1800Vdc DC system, limiting transient over-voltage caused by lightning and operational over-voltage caused by industrial switching, and realizing very low residual voltage while discharging high surge current to prevent damage of electrical equipments and prolong the service life of equipments.

EYZAO YSPD series primary, secondary and tertiary surge protectors combine safety and innovation brilliantly, using MG composite technology, no renewal current and no leakage current, extending the service life of the SPD and improving the efficiency of the power supply; EYZAO SPD miniaturized design, the width of each phase is only a modulus (18mm), so that the distribution box space is more plentiful, and with local and remote alarm function. Convenient maintenance; flexible chain discharge technology simplifies the installation of SPD, the upper and lower levels of SPD energy automatically with no decoupler, significantly improving the efficiency of surge protection and TOV tolerance, to ensure the stability of the power supply system.

EYZAO YSPD series surge protectors rely on automated production and precise testing technology to ensure the consistency and reliability of the product, and has obtained a number of authoritative quality certificates such as UL, CSA, TUV, CE, RoHS, CQC, etc., in line with the highest quality and safety standards in the global market, to ensure that your equipment is still safe to operate in bad weather.
