1. General

This specification defines the performance characteristic of an AC/DC switching adapter. The adapter must comply with all the requirements of the specifications and drawing herein. The requirements can be subject to revision in the future discussion.

2. Electrical Performance and Tests

2.1. Input

Voltage: AC100V ~240V

Frequency: 50/60Hz

Current: Maximum 500mA @ 100VAC and maximum 300mA @ 240VAC

Inrush Current: <20A@240VAC 50Hz (COOL)

Standby power: <0.3W

Rating Input load power: 25W

Starting Time <1S@240VAC Io=100%

2.2. Output

Voltage: 5.0V±5%

Current: 1A+2.4A

USB1=1A(D+=2.0V, D-=2.7V), for iphone,

USB2=2.4A(D+=2.7V, D-=2.7V), for mini ipad,

Ripple & Noise: Maximum300mV_P-P @ 100%

Note: 20MHz bandwidth ripple & noise is measured by using 0.1uF C.C. & 47uF E.C. bypassed at the output connector.

2.3. Hi-pot Test

Applying 3000VAC for 1 minute, leakage current must be less than 5mA.

2.4. Insulation Resistance

Minimum10Mohms @ DC500V

2.5. Short Circuit Protection

No damage to this power supply when output shorted to ground. When the short-circuited is removed, the adapter shall promptly recover its normal operation.

3. Mechanical Tests and Requirements

3.1. Drop Test

Drop height:1.0mabove50mmhardwood.

Method: Total 4 times. Drop one time for each of the 4 case surfaces.

Expected result: After drop test, the unit should still operate properly. Small nick or slight deformation may be accepted.

4. Environmental Conditions

4.1. Operating Temperature

0℃~ +40℃

4.2. Storage Temperature

-20℃~ +60℃

4.3. Humidity

90%RH Non-condensing

5. Safety Standard

Approved: CE/ETL   No. 60950.

6. Electromagnetic Compatibility

6.1. Conducted Emission

Meets class B of EN55022 & FCC part 15

6.2. Radiated Emission

Meets class B of EN55022 & FCC part 15
