Choosing a Surge Protection Supplier: An Introduction to LSP

  • Recommendation: ☆☆☆☆☆
  • To B or C: B2B


LSP has been committed to the design and production of surge protective devices (SPDs) since 2010. The company specializes in safeguarding critical electrical installations against transient overvoltages caused by switching events and lightning strikes. Having a history of specialized expertise, LSP has expanded to become a global provider, exporting to more than 10 countries and serving a wide variety of high-stakes industries.

LSP offers end-to-end protection services to clients such as electrical equipment distributors, manufacturers in the Photovoltaic (PV) and Energy Storage (ESS) industries, and telecommunications, power distribution, and industrial automation partners. They target major European countries, Russia, South Africa and Vietnam and have strategic plans to expand further.

A Focus on Premium Components & Materials

LSP is redefining the reliability standards in surge protection by designing its products on a platform of high-quality raw materials. This promise guarantees longevity, security, and extended working life.

  • Core Components (MOV and GDT): The reliability of an SPD begins with its core components. LSP uses LKD brand Metal Oxide Varistors (MOVs), the high-grade components that are used by the top-10 global SPD manufacturers. In the case of Gas Discharge Tubes (GDTs), LSP uses the Vactech brand, which is an element that has been trusted and adopted by other industry giants such as Phoenix Contact. This choice of high-quality internal components ensures high stability and performance.
  • Flame-Retardant Housing: Safety is first. LSP SPDs are housed in a plastic that is an improved flame-retardant material (PA6+GF30%). This material has been tested to meet the glow-wire tests and therefore will not add to a fire.
  • Durable Metal Components: All metal components such as terminals and pins are subjected to a 48-hour salt spray test. This is done to confirm a thicker and more resistant plating that is not easily corroded. Moreover, the metal contact pins are much stronger than competing products- 8mm wide and 0.8mm thick, they are more than 45 percent thicker, which guarantees a better connection and the possibility to work with huge currents without any harm.

Advanced Product Design & Technical Superiority

LSP integrates its high-quality materials with new technology. The product designs of the company have patented safety mechanisms and strong construction that has been tested to be superior to the industry standards.

  • Patented Safety Systems: LSP spent almost three years in research and development to master its internal disconnection (tripping) system. This proprietary process is effective in isolating and extinguishing internal arcs. This is an essential role in ensuring that the SPD does not overheat and ignite a fire during its end of life. This is combined with low-temperature tripping technology, which makes the SPD disconnect fully after a significant surge event, eliminating residual current leakage.
  • Superior Surge Endurance: SPDs of LSP are constructed to endure. Their Type 2 SPDs have been shown to be able to withstand a nominal discharge current (In) of 20kA with ±5 pulses and a maximum discharge current (Imax) of 40kA with ±1 pulse. The strong design of LSP guarantees stable parameters even when repeated events occur resulting in a service life of over 5 years.
  • Design to Real-World Conditions: LSP designs its products to withstand harsh environments. The core MOVs are not left uncovered but encapsulated (potted). This high-tech design eliminates moisture intrusion, enhances insulation, and shields the component against performance loss in wet environments. The products are also designed in a modular format, which can be used in both 3+1 (used in Europe) and 4+0 (used in China) modes, which provides flexibility to the global markets.

Robust Manufacturing & Stringent Quality Control

The quality of LSP is integrated into its production process that is controlled by strict international standards and confirmed by multi-stage testing.

  • Certified Production Plant: LSP has a 1600-square-meter factory with two automated production lines. The whole operation is certified according to ISO9001 standards and products are certified with TUV, CB and CE. This certified process can be used to produce 300,000 units annually.
  • Multi-stage QC Protocol: Quality is not inspected; it is designed and checked at each stage. LSP conducts a stringent battery of tests that extend beyond normal checks. This protocol includes:
    • Current tests of lightning impulse.
    • Thermal stability tests (long-term use simulation)
    • 8/20 µs waveform tests (for Type 2)
    • 10/350 µs waveform tests (for Type 1)
    • Three-parameter detection (Alpha value, leakage current, and residual voltage)
    • 48-hour salt spray tests on all metal parts.
    • Glow-wire tests on all plastic housings.
  • A 5-Year warranty that is not negotiable: LSP is confident in its materials and quality control, which is why it can provide a 5-year warranty on its products. This outstanding warranty gives partners and end-users a high level of peace of mind and reduces total cost of ownership.

Full-Cycle Customization & Engineering Support

LSP is a complete cycle manufacturing partner, which provides end-to-end customization services that enable clients to take their own unique ideas to market in a fast and efficient manner.

  • Concept to Branded Product: A two-person UG design team will help clients with professional customization solutions. This service includes visual design (custom logos, own labeling) to custom packaging and technical manuals. LSP also offers 3D modeling and product renders, which offer clients useful marketing resources even before the product is shipped.
  • Private Molds and Certification Services: In addition to aesthetics, LSP designs its own molds and certification services to make its products unique in terms of housing and features, which assist clients in standing out. One of the strengths is that LSP can offer TUV, CB, and CE sub-certificates. This service saves clients a lot of time and costs that would be incurred in independent testing and certification.

Comprehensive Service & Client Support

The service model of LSP is designed to be fast, flexible, and reliable, serving clients during the first inquiry to technical support after the installation.

  • Pre-Sales and Logistics: It starts with professional sales engineers who offer professional selection advice. Testing and validation (freight paid by clients) are free. LSP does not have a minimum order quantity (MOQ) and therefore it is an affordable partner for both large and small businesses. Lead times are short: 10-15 days on standard products and as short as one month on custom orders.
  • Post-Sales Commitment: The support is provided long after delivery. LSP ensures that any customer inquiry is responded to within 12 hours. The company also provides 7 days no-reason return policy and 30 days exchange policy. With the support of its 5-year warranty, the technical team will be able to offer remote support to troubleshoot any problems or instruct clients on how to replace SPD.
