1. There is a fuse at the AC input, two-level overcurrent protection

2. Over current protection, after the adapter's internal short circuit/overload, it needs to be safely isolated from the power grid;

3. Pressure-sensitive protection. After pressure-sensitive lightning strikes are damaged, it is necessary to ensure that the main circuit of the adapter input is disconnected;

4. The selection of overcurrent protection devices should consider that there should be no risk of melting shell under abnormal conditions;

5.4 Key items of safety test

Table 8 Safety test requirements

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 and UL/IEC/EN62368-1 section Q.1.

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. So the power supplier must carry out 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

Normal atmospheric pressure, relative humidity <90%, under non-condensing conditions, when the test voltage is 500VDC, the insulation resistance between the primary and the secondary is ≥100MW


Leakage current

<0.25mA (264VAC, 60Hz input)


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). Under normal working conditions, the housing temperature is required to be less than 75 degrees, and under abnormal conditions ((overcurrent, overvoltage and other two-zone environments)) the housing temperature is required to be less than 95 degrees.

The altitude must meet the 5000m requirement.
