Output Specifications:

Output Specifications:

1. Output Load:

Rated 40W for convection cooling.

2. Peak Load Duration:

Peak 60W can last for 5 sec. especially suitable for motor starting.

3. At peak load, the output can last for 5 seconds without shut down.

4. At factory, in 60% rated load condition, each output is checked to be within voltage accuracy.

5. Line regulation is defined by changing ±10% of input voltage from nominal line at rated load.

6. Load regulation is defined by changing ±40% of measured output load from 60% rated load.

7. Ripple & noise is measured by using 20MHz bandwidth limited oscilloscope and terminated each output with a 0.47uF capacitor at rated load and nominal

line.

8. Hold up time is measured from the end of the last charging pulse to the time which the main output drops down to low limit of main output at rated load

and nominal line.

9. Efficiency is measured at rated load, and nominal line.
