The Bulletin 1330 is an adjustable frequency, solid state inverter designed
for use with three-phase electric motors. Its use on single-phase motors is
not recommended. The slip characteristics of the motor must be analyzed to
assure a satisfactory application. Most three-phase motors designed to
operate on 60 Hz, 230V AC will operate satisfactorily on a combination of
adjustable frequency and voltage. The output torque will be essentially
constant over a range of 10 to 60 Hz while the motor goes through a speed
change of 1/6 base speed to full base speed.

Bulletin 1330 Drives contain high efficiency, high noise immunity CMOS
logic, and are available in 1.5 KVA (1 HP), 4 KVA (3 HP) and 6 KVA (5 HP)
versions.
