These surge protectors feature a compact design without compromising on performance, making them suitable for both residential and industrial applications. By diverting excess voltage to the ground, they protect sensitive devices from damage, extending their lifespan and ensuring uninterrupted operation.
Fast Response Time: Utilizes metal-oxide varistor (MOV) technology to react within nanoseconds, providing immediate protection against surges.
High Energy Absorption Capacity: Can handle surge currents up to 40kA (8/20μs waveform), making it suitable for high-energy transient events.
Multiple Protection Modes: Offers protection for both common-mode and differential-mode surges, ensuring comprehensive coverage for all types of installations.
Status Monitoring: Built-in LED indicators show the operational status, allowing easy visual inspection of the protector's condition.
Plug-and-Play Design: Easy to install in standard electrical panels, with replaceable modules for convenient maintenance.
The LY2 20 40 Series is widely used in:
Home Electronics: Protects televisions, computers, and home appliances from power surges caused by lightning or utility grid fluctuations.
Commercial Buildings: Installed in server rooms, security systems, and HVAC equipment to ensure continuous operation and data integrity.
Industrial Machinery: Safeguards control systems, PLCs, and motor drives in manufacturing plants, reducing downtime due to surge-related failures.
Telecommunications: Used in cell towers and network equipment to protect against surges induced by overhead cables or lightning strikes.
Q: How often should surge protectors be replaced?
A: It is recommended to replace them every 3-5 years or when the status indicator shows a fault, depending on the frequency of surge events.
Q: Can these protectors be used in three-phase systems?
A: Yes, three-phase models are available, designed to protect three-phase electrical systems effectively.
Q: Do they require a separate grounding system?
A: Yes, proper grounding is essential for optimal performance, and the protector should be connected to a dedicated grounding electrode.
Q: What is the operating temperature range?
A: The surge protectors operate reliably between -40°C and +85°C, suitable for extreme environmental conditions.
