About the FP3000-S6R-450-AN-D
FP3000-S6R-450-AN-D is a power unit that is manufactured by Reliance Electric for their FlexPak 3000 series. This particular part is an S-6R with a field rectifier. The nominal current is 450 A. The maximum AC-line voltage is 500 V. The U.S. model number associated with this part is 375FR8742. Avoid damage to the A-C line by doing the following: limit the AC line symmetrical fault current to 100 kA, limit the AC line symmetrical fault current (RMS) to 10 kA, minimize the supply system capacity, limit the line transformer impedance to 4%, limit the continuous undervoltage to 10%, avoid overvoltage transients.
