NOTE

| 1. All parameters NOT specially mentioned are measured at 800Vdc input, rated load and 25℃ of ambient temperature.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1μf & 47μf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. Derating may be needed under low input voltage. Please check the derating curve for more details.

5. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

6. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.

7. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”

Current sharing

1. Parallel operation is available by connecting the units shown as below (P+,P- are connected mutually in parallel) .

2. The voltage difference among each output should be minimized that less than 0.2V is required.

3. The total output current must not exceed the value determined by the following equation (Output current at parallel operation)

   • =(The rated current per unit) x (Number of unit) x 0.9.

4. In parallel operation 4 units is the maximum, please consult the manufacturer for other applications.

5. When in parallel operation, the minimum output load should be greater than 3% of total output load.
   (Min. load > 3% rated current per unit x number of unit)

6. In parallel operation, after overload or short circuit fault occurs, -. ) re-power on to recover.
