3.OUTPUT REQUIREMENTS:

3.1 Output Voltage and Current

Output	Output Regulation(V)		No Load	Rating Load (A)
Voltage(V)	Minimum	Maximum	Current(A)	Continuous Current(A)
12V	11.4V	12.6V	0A	2.5A

3.2 Output Voltage Regulation

The total output voltage regulation shall be +/-5%,including the effects of line voltage variations,load current,ripple and noise,and the AC component of the load current.

3.3 Output Voltage Ripple

The switching power supply shall not exceed the following limits in the indicated voltage for 60Hz or 50Hz ripple,switching frequency ripple and noise measured with 20MHz width.

Ripple and Noise:50/60Hz Ripple + Switching Ripple and Noise

Output	Ripple
