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 260mA @ 100VAC and maximum 150mA @ 240VAC

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

Standby power: <0.3W

Rating Input load power: 16W  max

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

2.2. Output

Voltage: 12.0V±5%

Current: 1A

Ripple & Noise: Maximum200mV_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

Minimum100Mohms @ 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.

3.2. Cord Bending Test

Bending angle: +60 degree

Bending rate: 20 times / minute

Loading:200g

Expected result: After 200 times of bending, the numbers of broken copper wire should be less than 50% of total numbers.
