POWER SUPPLY AND WIRING
Section 6
(continued)
For Frame Size 4 Controllers:
Single Phase Connection
For small drives with diode rectifier front end it is possible to run a three phase output with a single phase input.
Only part of the three phase input bridge is used. Ripple current becomes 120 Hz rather than 360. This places a
greater demand on the DC filter components (capacitor bank and DC choke). The result is that the drive must be
derated to 50% current.
If single phase input power is used the Motor Overload switches must be set to 50% or lower.
