Test items

Safety requirements

altitude

Insulation and distance


In considering the specifications above 2000m altitude, it is necessary to consider the correction of insulation parameters such as electrical clearance and creepage distance at high altitude. (The altitude needs to meet 5000m)

Secondary circuit

All secondary circuits must meet the requirements of the safety special ground voltage circuit (SELV).

Limited Power Supply Requirements (LPS)

Must meet the requirements of UL/IEC/EN60950-1 section 2.5.

Insulation resistance test

Japan no longer requires insulation resistance testing.

Although the insulation resistance test is not required in Singapore's national differences, the test result is still required when the final product enters Singapore for evaluation. Therefore, the power supplier must conduct this test and include it in the CB report.


5.5 Production line test requirements

100% withstand voltage test of the power supply during the production process

The ground continuity test is performed at the on and off positions of the input switch.

Table 9 Production line test requirements


Insulation voltage

(1) The primary to secondary should be able to withstand 50Hz, 3000VAC withstand voltage for 1 minute, leakage current ≤10mA, no breakdown or arcing;

The equivalent DC voltage can be used for testing.

Insulation resistance

5.6 Other

Meet the requirements of TT, TN, and IT power distribution systems.

The material of the adapter housing is required to reach the V-0 level (UL94). Meet the device derating requirements.
