DATA SHEET
Notes:
1. Combined power from main output, Vfan and Vs/b should not exceed total power rating.
2. Fan output tolerance is ± 20%. When V1 full load, Vfan needs 20 mA load to be within regulation specification. Peak
current for fan output is 1 A.
3. Ripple is 2% up to 20% load and less than 1% above 20% load. Output noise measurement is made with a 20 MHz
bandwidth using a 6” twisted pair, terminated with a 10 uF tantalum capacitor in parallel with a 0.1 uF ceramic capacitor.
4. Specifications are for nominal input voltage, 25° C and max load unless otherwise stated.
5. Air flow over length of supply recommended (either direction) for forced air rating.
6. Class 1 models have Earthing tab J4. Class 2 models (-2 suffix) have no Earthing tab.
7. Specifications may change without notice.
8. Warranty 2 years.
