OEM support
Surge protection device (SPD) is an indispensable device for lightning protection of electronic equipment.
It is used of limit the instantaneous overvoltage of the power line to the voltage range that the equipment or system can withstand, or a powerful lightning current drains into the ground to protect the protected equipment or system from impact and damage.
Enclosure material: Thermoplastic UL94-V0
Application:
Applied in SPD Class Ⅰ (Class B) for various power supply system of lightning current surge protection.
The SPD normally is installed in the building power distribution box, computer center, telecom room, elevator control room, wiring tv room, building control room, security monitor center, fire control center ,industry control room, frequency converter equipment control room, hospital surgery room, monitoring room and the distribution box in whichelectronic mechanical equipment.
The Type 1 surge protector is usually installed at the junction of LPZ0B and LPZ1
It can be installed in the low voltage power distribution cabinet/box of building.
It is suitable for distribution cabinets and distribution boxes with outdoor access lines in buildings.
Can handle lightning currents and protect sensitive electronic equipment.
Widely used in communication equipment, power, security, traffic, industrial control and other fields of power protection.
