Hitachi CONVENTION 14 Welding System User Manual


 
400V Class Inverters The following
tables specify the braking options for
400V class X200 inverters and the
braking torque for each option. You can
connect a single braking unit to the
inverter, or two braking units for
additional braking torque.
Use one BRD-EZ3 braking unit for the
braking torque listed in the following
table.
