What cooling measures are required for high current loads?

Install a heat sink for loads over 10A. For currents over 40A, add a fan for force cooling or water cooling. For currents over 60A, a cooling fan is required.

What are the load ratios for different equipment types?

The ratio depends on the load: Resistive load is 70%, Inductive load is 20%, and Capacitive load is 10%.

What is the minimum order quantity?

The minimum order quantity is 10 pieces.

AI-Powered supplier vetting

SummaryYueqing Chuxi Electric Co., Ltd. is a China-based limited trading company established in 2016, with three employees and products including sensors, switching power supplies, float switches, and solid-state relays. It reports OEM service for well-known brands, ODM availability, and broad customization services. However, no supplier-management-system certification is reported, no new products were launched during the past year, and no SDK is available. Service-management procedures, complaint-handling procedures, corrective and preventive action records, and raw-material traceability are not documented or are unknown. The supplier has substantial export activity, but no valid import/export license is reported and exports may be conducted through agents. Financial evidence is limited to referenced years without disclosed financial figures. The available information supports customization and reported OEM/ODM capability, while production scale, after-sales controls, financial credibility, and customer-case...

CertificationsNo supplier-management-system certification is reported. An SGS audit is documented with a report period from September 24, 2024 to September 23, 2025, but the recorded audit result is 0 and no specific certification or favorable evaluation is provided.

After-Sales capabilityThe supplier lists 10 qualified service suppliers and provides some supplier names, but it has no written procedures or records for service-capability assessment, corrective and preventive actions, or effective customer-complaint handling. This explicitly indicates deficiencies in documented after-sales management controls.

R&D capabilityThe supplier reports one year of total R&D-engineer experience, no new products during the past year, and no available SDK. Although ODM service and multiple customization options are offered, the stated lack of recent product development and SDK support does not demonstrate strong independent innovation.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM availability, providing direct evidence of broad stated customization services.

Product Q&A

Q:Can I use this relay for solar equipment?

Solar equipment is a mixed load and we do not recommend using solid state relays. If you must try, buy a relay with 10 times the current. Note that we do not provide return service if it fails on solar equipment.

Q:What is the warranty period for this product?

All products sold come with a 2-year warranty covering defects.

Q:Do you accept customized orders?

Yes, OEM and ODM are available. We accept customized products from samples, designs, and offer flexible minor customization options.

Q:What is the lead time for samples and bulk orders?

Samples under 100pcs take 4 days. General orders under 10,000pcs take 7-15 days. We have dedicated production lines to ensure timely delivery.

Q:How should I test the switching state of this relay?

Do not use a multimeter diode or resistor test as it will show high impedance. Use an incandescent lamp as a dummy load to test continuity properly.
