Low voltage operation

With the addition of a 24 Vdc power supply to supply the control circuits, the drive is able to operate from a low voltage DC supply with a range of
voltages from 24 Vdc to the maximum DC voltage for the given drive. The working voltage ranges for the low voltage DC power supply are as follows:
Size 3 to 7
Minimum continuous operating voltage:
Minimum start up voltage:
Maximum over voltage trip threshold:
