Motor Mounted Speed Control
1/8 HP, 90 VDC, 2.5 AMPS, FIELD INSTALLED
Designed to be easily field mounted on Bison PMDC motors, the
speed control is mounted within an aluminum extrusion for superior
heat dissipation. A simple knob provides a convenient on-off switch.
Three adjustable potentiometers provide settings for minimum RPM,
maximum RPM, and current limit. A pre-wired three foot long cord
with plug is provided for use with 115V, 60 Hz.
nSimple Mounting and Assembly. Allows the drive to start
working for you in the field as quickly as possible
nEasy Operation. Speed is controlled with a simple on/off
potentiometer in conjunction with current limit, min. speed,
and max. speed settings
nAll Metal Enclosure. Durable aluminum housing with steel
cover plates disperses heat more efficiently

the torque reference, the on-board torque pot sets maximum speed and the on-board Max Speed pot
sets maximum torque.

Dual SCR Chassis
The Dual SCR drive provides the power of two drives in one! Now with one DC drive, you can control
two different DC motors either independently or in a ratio mode. In independent mode, each side of
the drive can be controlled differently with different trimmer pot settings and different speeds. In speed
ratio mode, one speed potentiometer sets the main speed while the other one determines the ratio of
the speeds between the motors. In this mode, the drive replaces two single drives and possibly a separate
master/follower card resulting in extreme cost and panel space savings!
n
Ability to control two different DC motors at once: Jumper selectable
independent or speed ratio mode.
nIndustry Standard footprint for chassis mount
nUser adjustable calibration pots: Two each of minimum speed,
maximum speed, IR compensation, current limit and
acceleration / deceleration.
nStopping Modes: Decelerate or coast (jumper selectable) using
inhibit function (N.O.)

industry standard mounting hole pattern.
n Easy to Calibrate & set up: On board trimmer pot adjustments
for boost, maximum speed, acceleration, deceleration.
n Torque “foldback’ feature: Allows up to 200% torque for short
periods to overcome intermittent peak loads, then reduces the
torque to a preset safe level.
n 16kHz switching frequency, with option to change between
4 and 16 kHz in the field: A high switching frequency results
in quiet motor operation. Adjustments to a lower frequency if
desired can be done in the field.
