BBVF
Adjustable Frequency Drive
New AC Inverter Breaks $150 Barrier
For Motor Speed Controls
Dramatic advances in semiconductor technology and cost effective
power switching devices are resulting in significant price reductions in
adjustable speed drives. In line with these technology advances, B&B Motor
& Control Corp. has announced it's new family of NOVA AC, AC inverter motor
speed controls.
The Nova AC, BBVF Adjustable Frequency Drive, is available in
1/2HP or 1 HP, configurations, and provides easy to use, variable speed control
of three-phase AC induction motors. Adjustable linear acceleration and
deceleration are provided, making the drive ideal for soft start applications as
well.
The output voltage is sinewave coded PWM operating at 16 kHz,
which provides high motor torque, high efficiency and low noise. The BBVF is a
full-featured drive with full torque over a 30:1 speed range. The unit operates
from 115 or 230 VAC single phase input, to drive standard 208-230 VAC 3-phase
motors. Simple trimpot adjustments eliminate computer-like programming required
on other drives, however, for most applications, no adjustments are necessary.
Other features include RMS current limit, I²t motor overload protection,
electronic current inrush limit and a built in dV/dT filter to reduce voltage
spikes to the motor. The BBVF also includes LED diagnostic indicators. The
unit's footprint is only 4.6" x 4.3".
The BBVF AC Inverter Drive From B&B offers
one of the best values today in the adjustable speed control market. This drive
is ideal for both user and OEM applications, and is truly an exceptional value.
Choose from either the 1/2 or 1 HP model.
