Hi all,
I am trying to re-design our current power supply to meet GR-1089-Core Specification. The Power Supply has a -48V input and 5VDC/100W, 5VDC/100W and 12VDC/150W Output. Based on current testing, we did not comply with Section 9.10.6 Frame Surge Test. This test applies a surge current as defined in IEEE C62.41. The filter capacitor was destroyed during this test. The capacitor is rated at 100V. I think this capacitor should be replaced with a higher voltage X or Y capacitor. Possibly a GDT or TVS is required. If anyone can help, I will email a portion of the schematic in PDF format. Thank you, Mark Pascarelli Electrical Engineer Carlo Gavazzi, Inc. ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
