Steps to Ensure Equipment is Not Damaged by Voltage surges

Ensure good low-impedance ground connection, match SPD Uc rating to equipment voltage, protect PV module and AC inputs, and use SPDs rated for the correct DC or AC voltage.

Are Surge Protectors and Lightning Arresters the Same Thing?

No. Surge protectors protect electronic devices from power surges using components like MOVs. Lightning arresters protect buildings from lightning strikes by providing a path to ground.

AI-Powered supplier vetting

SummaryAswich Electrical Co., Ltd is an established electrical-component manufacturer founded in 1988, with more than 30 years of experience, a 30,000-square-meter production base, automated production lines, and stated annual DC isolator output of 1,000,000 pieces. It demonstrates broad customization capability, recent new-product activity, quality assurance, ISO9001:2015 and ISO14001 accreditation, and UL-related certification capability. Customer complaint handling is documented, but corrective and preventive actions for service capability lack written procedures or records. The supplier has valid manufacturing contracts with associated subcontractors but reports no inventory, overseas warehouse, overseas showroom, overseas agents, or branches. Financial information is present for multiple years, but the provided slices do not establish financial strength. No specific customer cases or named customers are supplied.

Supplier typeThe supplier is identified as an electrical and electrical-component manufacturer and seller, with experience manufacturing switches and circuit breakers since 1988. Its owned production base, laboratory, automated lines, and stated DC isolator output support classification as a manufacturer rather than only a trader.

CertificationsThe company is stated to hold ISO9001:2015 and ISO14001 accreditation, and its sustainable-development and product-certification capability lists UL and other certifications. These are explicit certification-related strengths, although the specific UL-certified products are not identified.

After-Sales capabilityThe supplier has a clear procedure and followed records for customer complaints, but it has no written procedures or records for corrective and preventive actions related to service capability. It also reports no inventory, overseas warehouse, overseas showroom, overseas agents, or branches, limiting evidence of local or rapid overseas support.

R&D capabilityThe supplier reports new products during the past year, high R&D investment, 50 total years of R&D engineer experience, and a national science and technology progress award. It does not provide an SDK and does not offer ODM services, but these limitations do not negate the explicit evidence of product R&D capability.

Production capacityProduction evidence includes a 30,000-square-meter plant, multiple automated production lines, an owned laboratory, valid contracts with each associated subcontractor, and stated DC isolator output of 1,000,000 pieces. Finished products are checked by packing staff, while no inventory capability is reported; overall manufacturing capacity is supported, but the inspection method appears limited in the provided information.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. This is reinforced by the listed design-service capability for customization from samples, demonstrating broad stated customization coverage.

Product Q&A

Q:What are the different types of Dc surge protectors?

There are two main types of DC surge protectors: DC surge arresters used for high-energy surges like lightning, and DC surge filters used for low-energy surges like switching transients.

Q:How to Properly Configure SPDs in Dc Systems?

Select the right type (arrester or filter), size the SPD correctly for the energy, and install it properly with a good ground connection. Ensure high voltage rating, low let-through voltage, fast response time, and long life expectancy.

Q:Where should DC surge protectors be installed?

DC surge protectors should be installed in all areas with sensitive equipment, including data centers, telecommunications facilities, industrial control systems, and medical facilities.

Q:What are the benefits of using Dc surge protectors?

Benefits include protection against damage to sensitive equipment, increased uptime for critical systems, reduced maintenance costs, and improved safety for personnel.

Q:What are the three classes of Dc surge protectors?

Class I withstands highest energy (lightning) for critical applications. Class II withstands medium energy (switching) for commercial/industrial use. Class III withstands low energy (everyday use) for residential applications.
