Photovoltaic DC fuse is a safety device used to protect photovoltaic cell components, inverters and DC loads. In order to ensure its safety and reliability, UL248 certification is required.
Before applying for UL248 certification, it is first necessary to determine that the product meets the requirements of UL standards. UL standards can be obtained through the official website or related information. Then, you need to select a qualified third-party testing agency-Accorfor testing.
The testing company will conduct a number of tests on photovoltaic DC fuses, including electrical performance, mechanical performance, insulation performance, etc. The test results need to meet the requirements of UL standards.
In general, the following steps are required for UL248 certification:
1. Product evaluation: first evaluate the material and construction of the product to determine whether it meets the requirements of UL standard.
2. Test plan development: develop a test plan according to the requirements of UL standards and confirm with the testing company.
3. Test: Send the photovoltaic DC fuse to Ancorer for testing. Testing will include realistic simulation testing through electrical, mechanical and environmental conditions.
4. Test report evaluation: Ancorset will generate test reports according to the requirements of UL standards, and evaluate whether the results of the report meet the requirements of UL standards.
5. Certification mark authorization: After passing UL verification and confirming that the product meets UL standards, the product conformity mark will be granted.
To sum up, the photovoltaic DC fuse to apply for UL248 certification is required to strictly comply with the requirements of UL standards, and select a third-party testing organization that meets the requirements-Ancoret for testing. Only by passing the UL248 certification and obtaining the certification mark authorization can the safety and reliability of the product be proved.
