ORDERING PROCEDURE - Required Equipment
1 SPECIFY THE POWER SUPPLIES
Two power supplies are available as part of the PAC-500 system: the H-401 and the H-601.
See the Power Supply Selection Guide below to determine which and how many power
supplies to order.
H-401 Power supply
This unit is a three-phase power source using SCRs in a full-wave bridge rectifier circuit
for providing up to 400 amps of power at 100% duty cycle. The H-401 can be used
independently or paralleled with another H-401 or with an H-601 depending on the plate
type and thickness to be cut. See Power Supply Selection Guide below. The power
supply interfaces with the PAC-500 control console and the workpiece.
H-601 Power supply
This unit is a three-phase power source using SCRs in a full-wave bridge rectifier circuit
for providing up to 600 amps of power at 100% duty cycle. The H-601 can be used
independently or paralleled with an H-401 or H-601 depending on the plate type and
thickness to be cut. See Power Supply Selection Guide below. The power supply
interfaces with the PAC-500 control console and the workpiece.
• Using the Power Supply Selection Guide below, determine which supply (supplies) are
needed for the particular application. Determine the placement of the power supply
(supplies) and input line voltage available at the site and order the appropriate power
supply or power supply combination.
