| SCF (open style) drives 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: Approved as a 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 (open style) drives
Suitable for installation in your controls enclosure. Alternatively, we
stock vented enclosures designed especially for these open style devices. Add a Stop/Start
selector and Speed potentiometer kit, mount both on the enclosure door, and see just how
inexpensive variable speed control can be. |

THE MC SERIES - The
secret of a great microdrive Building a great microdrive requires listening to
customers that apply them day in and day out. They need to be ready for any environment,
any supply voltage and over a wide power range. And, since the machines and processes
where they will be applied are so varied, they need to have the functions that lend
flexibility yet still be easy to set up and operate.
Impossible? No, it’s AC Tech’s MC Series!
These variable frequency drives will accept input from single-phase power (with 1.73
derate for motor HP). As example, a 20 HP drive is required to power a 10 HP electric
motor when the drive is connected to a single-phase source. |
| General
Specifications Horsepower: ¼ to 60
HP (0.18 to 44kW)
Supply Power:
• Single Phase: (with 1.73 derate).
• Three Phase: 208, 240, 400, 480 or 590VAC
50 or 60 Hz (+10/-15%)
Motors: The MC Series variable speed drive is designed to operate standard
polyphase induction motors rated for 200, 230, 400, 460 or 575VAC from 0 to 120Hz.
Operation to 1000 Hz is an available option.
Enclosure:
• NEMA 1 for clean environments
• NEMA 12 dust-tight/oil-tight for dirty areas.
• NEMA 4 water resistant for wash down areas.
• NEMA 4X in stainless steel for corrosive or caustic environments
Standard Features
Easy setup and operation: The MC variable speed drive offers intuitive operator
interface using plain English programming and operational information.
• 16 character backlit display
• Keypad for operation and programming
• Personal computer interface using AC Tech’s free TechLink Software
Motor Thermal Overload: The MC includes UL and cUL approved motor protection
device for single motor applications.
The MC Drives
MC Series drives are available in two versions:
• M1000 Series for standard applications
• M3000 Series for process control
M1000 Series
Designed for typical constant torque applications where motor speed is controlled from the
drive keypad, a 0-10vdc or 4-20ma control signal, or a standard potentiometer. The M1000
series provides bi-directional control of the motor over a range of 0 to 120Hz. High speed
operation up to 1000Hz is optional.
M3000 Series
Designed for processes where set-point control is required. The PID control algorithm in
the M3000 Series is applicable on both constant and variable torque loads. Applications
include fans, pumps, material feed conveyors, and rock crushers to name a few.
MC Series Options
Dynamic Braking: For faster stopping or for improved speed control, dynamic brake
control with external resistors can easily be added.
Remote Keypad: When mounting the MC drive within another enclosure, a remote
keypad and display can be brought out for operator interface.
Additional Form-C Relay: Converts one of the open-collector outputs to a form-C
Relay.
Metasys® communication protocol: The MC3000 can support RS-485 serial
communication for Johnson Controls Systems.

Several names exist for the same products. Throughout the
industry, VFDs are often referred to as;
- Variable speed drives
- Variable frequency drives
- AC inverter drives
- VFDs / AFDs
- Adjustable frequency drives
- Adjustable speed drives
Call them what you may, just make sure you ask for AC Tech drives! |
