Best Price for Spd Types - 36 Sidall Structure Voltage switching type ac lightning surge protector (10/350μs) – Leihao

When the thunderstorm season is coming, lightning protection is particularly important at this time. Lightning enters the room through power lines or other ways, causing damage to people and equipment; LEIHAO Lightning Protection Company has many excellent lightning protection products, of which the surge protector of power supply is an important part. Now we will briefly introduce the parameters and uses of a first-class surge protector.

(1) in the front end of the main power switch in the floor distribution box, LH-50I 4P is generally used as the primary protection of power supply;

② LH-50I 4P should also be used at the low voltage end of transformer and the front end of main power switch.
③ When the distribution box is independent outdoors, LH-50I 4P should also be used as the primary power protection.Equipment connected to AC power supply network is easily affected by many electrical problems that may be expected in unstable operation, which leads to equipment failure, life reduction and even damage. LH-15I series surge protectors are designed to meet the protection requirements of all low-voltage devices for industrial lightning surge.  The product range of this series is classified by product type and power supply category (AC or DC).

Risk of voltage surges

Electrical and electronic eauipment is indispensable in the daily activities of today’s businesses and individuals. Such devices are connected to the electricity grid, often exchanging data and signals through communication lines and are usually sensitive to disturbances. These interconnecting networks provide a propagation path for overvoltages.

Protection against lightning and overvoltages not only ensures the safety of people,goods and equipment, but also ensures continuity of installation services. Overvoltage protection extends the life of the equipment by more than 20%, which significantly reduces the volume of electronic waste. It also reduces the power consumption of the installations, all of which translates into cost savings and environmental sustainability.
