Notes:
1. An input line fuse is recommended for use (e.g. Littelfuse type, 10A 250V FB).
2. External input capacitance required. See Figure 1 for the Input Reflected-Ripple Current Test Setup.
Measure input reflected-ripple current with a simulated source inductance of 12µH.
3. See Figure 2 for the Inrush Current Test Setup. Measure input inrush current with a simulated source
inductance of 12µH and input bulk capacitor of 68µF/450Vmin must always be added.
4. The combination of remote sense and trim do not exceed a total of 0.5V.
5. Refer to Basic Operation and Features section.
6. See Figure 3 for modules in parallel connection.
7. The AUX output pin does not allow for any short circuit and OCP testing.
