9 Over voltage protection Use the Zener diode to protect the output.

10

Short circuit protection

The adapter will shut

down and will not been

damaged.

If short circuit occurs, all the output should be

protected. After the fault, the adapter

automatically recovers.

11 Dielectric Strength

production test.

DC500V shall be applied for 1min. between

Primary and Secondary, Primary and case

12 Insulation resistance ≥20MΩ DC500V shall be applied for 1min. between

Secondary and case.

13 Cord bending test ≥1000 times

The DC cord shall withstand weight of 500g,it

swing from left to right at angle of 120 degree, 40

times per min.

14 Strain relief test No damaged after the

test

Fix the main part of the adapter, Plug and cord at

their normal position applied a weight of 5 Kg to

output for 15 seconds.

15 High temperature

storage test

The adapter shall be storaged at temperature of

40±2℃，for 24hours.

16 Low temperature storage

test

The adapter shall be storaged at temperature of

0±2 for 24℃hours.

17
