Functions and Features
The following is a list of available features not included in every control. See ordering instructions for how to order listed
features.
Standard Features:
Controlled Acceleration
An adjustable function that allows smooth acceleration on
vehicles of varying weights and speeds.
See potentiometer adjustments on page 3.
Current Limit
An adjustable function that renders self-protection to the
control and the traction motor.
See potentiometer adjustments on page 3.
Thermal Protection
A protection circuit that reduces control output, if needed, to
maintain rated component temperature. Switching frequency
is reduced at ~ 60oC.
Accelerator Volts Hold Off (Option)
This feature assures that the accelerator is calling for low
speed operation at start up.
Plug Braking (Option)
An adjustable function that allows smooth braking on
vehicles of varying weights and speeds.
See potentiometer adjustments on page 3.
High Frequency Operation
This feature provides oscillation frequency of 13 kHz. The
high oscillation rate allows for quieter operation, higher
average motor current with lower peak motor currents, less
ripple current at the motor, and less motor heating.
Reversed Battery Protection
(With Line Contactor and Diode) This function disables the
operation of the control if the battery connections are
reversed.
Low Voltage
The control is designed for use down to the following
voltages:
24/36V: 16V cutout
36/48V: 19V cutout
48/72V: 25V cutout
72/96V: 36V cutout
120/144V: 60V cutout
The control will not operate when the cutout voltage is
reached.

Installation Tips:
Using heat transfer compound (FSIP P/N: 43-8012-30) between the motor control and the mounting plate of the vehicle will enhance
performance on heavy-duty applications. A thin coating that covers the mounting surface gives the best heat transfer.
Do not allow controller to come in direct contact with battery acid, water, or power washing. These contaminants can get inside
controller and cause circuit board damage which will cause premature failure and may void warranty.
•Always use safe practices while working on electric vehicles.
•When appropriate, lift the drive wheels off the ground.
•Disconnect the batteries before removing or installing controllers.
•Verify all electrical connections are secure. Improper connections will cause heat and could damage drive system.
Warranty and Service
This product is covered by a 12-month warranty. Worldwide technical assistance and service are available from local FSIP
representatives.
