LSP has a team of experienced UG designers, graphic designers, and mold designers dedicated to meeting various OEM/ODM requirements for high-quality surge protection devices.
LSP provides custom exterior design services, enabling clients to develop unique identities for their surge protection devices that are tailored to their brand.
LSP guarantees fast and secure delivery by partnering with top global logistics providers, ensuring that customers receive our surge protection devices on time.
LSP's surge protection device products come with a comprehensive 5-year warranty, providing long-term assurance and peace of mind for our valued customers.
LSP’s surge protection devices feature durable LKD MOVs, precise disconnection, and customized soldering, ensuring reliable performance for up to 5 years.
We use high-quality LKD MOVs in our surge protection devices.
we use encapsulation film to seal the MOVs, ensuring environmental protection, moisture resistance, safe handling, and insulation.
Our MOVs undergo 8/20μs impulse testing and can withstand more than 10 impulses.
Moreover, after these 10 impulses, the MOVs maintain their three parameter values within specified limits, ensuring the quality and reliability of our superior surge protection devices.
After tripping during a surge, LSP creates a separate chamber that ensures complete isolation and arc extinction.
LSP’s surge protection device undergo rigorous testing, including lightning impulse, thermal stability, salt spray, glow wire, and current impulse tests,
ensuring quick disconnection, heat resistance, corrosion protection, flame resistance, and durability.
This test assesses the flame resistance of all plastic components in the surge protection device to ensure the safety of connected equipment.
Through rigorous flame testing, it evaluates the performance of these plastic materials when exposed to high temperatures and flames, effectively preventing potential equipment damage or safety hazards caused by fire.
Ensuring that all plastic components meet industry standards not only enhances the overall reliability of the product but also provides users with greater safety assurance.
This test confirms the surge protection device’s capability to quickly and safely disconnect during a high-intensity, short-duration voltage surge.
The ability to respond rapidly to these electromagnetic surges is essential for safeguarding the entire electrical system from potential electromagnetic damage.
By ensuring that the surge protector can effectively isolate the electrical circuit during such events, this test helps prevent catastrophic failures and prolongs the lifespan of connected devices.
This test uses prolonged high-temperature operation to ensure the solder joints in the surge protection device remain stable under continuous heat.
By subjecting the device to extended periods of high elevated temperatures, we can thoroughly assess the durability and overall integrity of the solder connections.
This test activates the disconnection mechanism only after sufficient thermal energy has built up, allowing us to accurately evaluate the device’s ability to endure extreme conditions without failing.
This test focuses on the metal components of the surge protection device, verifying their resistance to rust and corrosion in humid conditions.
By exposing these components to controlled humidity levels, we can assess how well they withstand environmental factors that typically contribute to degradation over time.
This evaluation not only helps in selecting suitable materials but also guarantees that the surge protector will reliably operate in various environments, safeguarding connected equipment from electrical surges.
This test ensures the internal Metal Oxide Varistor (MOV) of the surge protection endures over 10 current surges without failure or breakdown.
By subjecting the Metal Oxide Varistor (MOV) to a series of controlled surge events, we evaluate its resilience and effectiveness in handling repeated stress.
The test not only demonstrates the MOV’s durability but also reinforces the overall protection provided to sensitive electronic equipment, preventing potential damage and ensuring safe operation.
