2.3 3 PHASE INPUT POWER REQUIREMENTS
The total input Volt/Ampere requirement for this equipment is approximately 22500 V/A.. This number
is based on a balanced, purely resistive load applied to the output at 135Vac. The actual input V/A
product is somewhat dependent on the quality and impedance of the input line provided to it. The
BL20000 series power supplies within the model number range C2 to C6 are designed to be used with
a four wire “ Wye” input configurations. Delta configurations above 277 volts require the addition of
back-up fuses for proper safety. The chart below indicates the proper fuse based on the model number
of the power supply.
The following lists should be used to select the proper line fuse size for the model numbers shown. The
selections are based on nominal line voltages and maximum output power. All fuses carry a 600 Vac
rating. DO NOT substitute any other fuse voltage . See warning on following page.
