Vari Speed® R400 speed/torque control

for VA to 2 HP DC motors

The Vari Speed9' R400 is a full-wave

DC regenerative control that provides

high performance four quadrant

speed and torque control. The R400

solid state controller converts single

phase AC line power into an adjust-

able DC power to control 1/4 to 2

horsepower DC motors.

The R400's flexible design is easily

selectable for speed or torque mode,

tachometer voltage, dual voltage and

for horsepower size. The R400 is

designed with today's most desirable

features including isolated input

signals, status indicators, alarm

outputs. When performing frequent

directional changes, the R400 trans-

fers excess system energy back to

the AC line rather than wasting

additional energy by the use of a

dynamic brake resistor.

The R400 is designed, engineered

and manufactured in the USA, and is

UL and cUL listed.
