A. INPUT CHARACTERIZATION

1。1 INPUT CURRENT/POWER/EFFICIENCY/POWER FACTOR

Test conditions:
The unit is set at maximum load and the input voltage is varied from the minimum to the maximum value. Efficiency is computed and Power Factor is either computed or measured after 10 minutes warm up at least。

Test equipment:
Chroma Model 8000 Power Supply Auto Test System
Chroma Model # 6590 9KVA Low Impedance AC Source
Chroma Model # 630X0 DC Load
Chroma Model ＃ 6630 Power Analyzer

Pass/Fail criteria：
The unit test shall meet the specification requirements.

Test result: PASS

1.3 ACOUSTIC NOISE

Test conditions:
Measurements to determine the AC adapter sound pressure are made using a 1/2” low noise free—field microphone in a inner size with 45(W)×45（D）×65（H） cm^3 Anechoic chamber。

Test equipment:
Anechoic Chamber： Free-Field Acoustics Corp. Lower than 10dB(A) background noise。
B ＆ K Portable Pulse – Type 3560C, Microphone： 4190， Preamplifier: 2669L

Pass/Fail criteria:
The AC Adapter shall produce no human perceivable audible noise （less then 25dB）.

Test result: PASS

Acoustic Noise Test Set-Up
1。4 INRUSH CURRENT

Test condition:

For cold start test at room ambient, the adapter should be off for at least one hour at the test temperature to ensure it is at a uniform temperature before the test is started. Turn on the UUT
at 90 degrees at positive cycle or 270 degrees at negative cycle。 Between each test， the UUT shall be cooled down for at least 3 minutes and the Bulk Cap’s Energy is discharged。

For hot start test at max。 Operating ambient, the adapter should be on and running for at least one hour at the test temperature to ensure it is at a uniform temperature before the test is started。— Repetitive ON/OFF （1Sec. ON/1Sec. OFF for 10 times） cycling of the UUT and turn on at 90 degrees at positive cycle or 270 degrees at negative cycle。 Between each test， the Bulk Cap's Energy shall be discharged.
