terminals.
Standard Features
Easy Set-up and Operation:
The SCF is easy to use right out of the box or can be customized to
meet your specific requirements any one of four convenient ways:
- From the front of the drive
- From the remote keypad option
- A PC (and AC Tech’s free TechLink
Software)
- The innovative EPM Programmer.
Motor Thermal Overload:
The SCF is an approved motor protection device for single motor
applications by UL and cUL.
Control I/O:18 isolated terminals
provide 5 logic inputs, 2 logic outputs, 2 analog inputs and 2 analog
outputs plus RS485 Modbus Serial Communication.
Quiet Operation: Adjustable carrier
frequency to 10kHz.

SCF
Options
NEMA 4X Remote Keypad:
Connects to SCF over RS485.
Allows operation and programming
of the drive.
(instruction sheet available in Library)
High
Frequency Output Option:
Contact AC Tech for SCF Models for high speed applications up to
1000Hz.
Set-point
Control:
All models of the SCF are available in an optional configuration that
allows for set-point control using an internal PI (proportional &
integral) control algorithm. This is ideal for process control
applications where constant flow, pressure, density, etc are desired.
DIN Rail
Mounting Kit:
Allows easy mounting of the SCF Drive onto standard DIN Rail.
(instruction sheet available in Library)
Dynamic
Braking Kit:
Prepackaged resistor modules with control electronics provide easy
mounting within the control cabinet.
(instruction sheet available in Library)
AC Line
Filters:
AC input line filters are available for all sub-micro drives to meet
European requirements for susceptibility and emissions of electrical
and radiated noise (EN 61800-3 and EN 5501). The filter is designed to
mount to the electrical panel and has provisions for mounting the
drive directly to the face of the filter.
EPM
Programmer:
This compact battery operated option allows programming the EPM (on
the front of each drive) directly and without power to the drive!
Copy drive parameters easily or write new ones using the backlit LCD
display that uses real language programming.
