Appendix A
Applying More Than One ArmorStart LT Motor Controller in a Single Branch Circuit on Industrial Machinery
Supplementary Note 1:
The input currents to the Bulletin 294E motor
controllers are larger than the output currents to the motor because the input
currents contain harmonics resulting from the power conversion process.
This harmonic content and the magnitude of the resulting non-sinusoidal input
currents depend on the impedance of the electrical supply. The value specified
for the rated input current is the maximum value over the range of possible supply
impedances. For this reason, the magnitude of current measured on a particular
electrical system may be less than the specified value.
