Also use 10A 3AG fast blow fuse ahead of line filter. PART NUMBERING OUTPUT Output power 600/675W Output ripple (pk-pk) 7mV pk-pk Holdup capacitance 420-3000µF Short circuit protection Yes MECHANICAL Dimensions 117x61x12.7mm OPERATING Efficiency 90%-94% Isolation Input - Output: ZeroInput - Baseplate - Output: 2500V rms 85°C Baseplate operating temperature Thermal shutdown If power requirements exceed one HAM, use a HAMD and one or more BAMDs, with an external bridge rectifer. HAM, HAMD, and BAMD modules require three surge suppressors in series directly across the input. These surge suppressors are already contained in the EMI filter P/N 30205. Also use a 10A, 3AG fast-blow fuse ahead of the line filter. * Compatible with V375 series. 90°C to 100°C TYPICAL APPLICATION VI-HAM Doc. No. PBC9 Rev.C 28-4-11
