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.
The chart below shows the full load output current ratings of the controller when single phase or 3 phase
power is used. If single phase input power is used the Motor Overload switches must be set to 50% or lower.
