Ready - Set - Go Small drive maximum strength and reliabilty.

The new Micro drive.  Low cost but with the heart of a Lion.  This drive uses the same personality of our proven VLT5000 series.  Built in smart logic controller and safety features.  Digital and analog I/O.  Built in RFI. 150% of motor torque (not weasel word current).  Coated and protected circuit boards.  Plug and play, set it and forget it.  EIA-485 port with FC or Modbus RTU protocol.  A must buy for the serious drive users. 

VLT® AutomationVT Drive FC 322
The VLT® AutomationVT Drives are specifically engineered to save energy, reduce up front and operating costs, and maximize uptime in industrial variable torque fan, pump, blower and compressor applications. They are available for 240 and 480 VAC single and three phase, or 575 and 690 VAC three phase operation with ½ up to 1400 HP, along with a wide range of industrial enclosure options, to support varied performance needs.
VLT® Soft Starter MCD 500

VLT® Soft Starter MCD 500 is a total motor starting solution. Current transformers measure motor current and provide feedback for controlled motor ramp profiles. AAC, the Adaptive Acceleration Control automatically employs the best starting and stopping profile for the application.                

Revolutionary Danfosss One Gear
VLT® OneGearDrive
With the VLT® OneGearDrive concept, Danfoss has developed a more flexible, more efficient drive system that significantly reduces the number of drive variants across a typical food
& beverage or materials handling process plant, resulting in greatly reduced operating costs and substantial energy savings.
VLT® Decentral Drive FCD 302
VLT® Decentral Drive FCD 302
With the introduction of the new VLT® Decentral Drive FCD 302, Danfoss has raised the bar on the design and functionality of decentral drives – setting new performance standards like open loop operation of permanent magnet motors.
VLT® AutomationDrive FC300

Engineered for design simplicity and high performance

The VLT® AutomationDrive represents a single drive concept that controls the entire range of operations from standard to servo motors on any machine or production line. The modular open-technology platform on which the VLT AutomationDrive is built makes it exceptionally adaptable and programmable.Its configurable, user-friendly interface supports local languages and letters. With the VLT AutomationDrive series we have intelligent plug-and-play technology and unmatched reliability making drive operation pure childs play.

Complete Range of Drives

  • From 1/3 to 1200 HP
  • Chassis, NEMA/UL Type 1, 12, 4X with or without disconnect,
VLT® Decentral FCD 300
VLT® Decentral FCD 300
The VLT FCD 300 is a complete frequency converter designed for decentral mounting.The FCD 300 can be mounted on the wall close to the motor, or directly on the motor. The FCD 300 comes in a high enclosure class, IP66, to withstand normal cleaning methods.

The design offers a smooth cleaning friendly surface without any spots difficult to clean. The FCD 300 comes in a robust painted surface. The decentral design reduce need for central control panels and space-consuming motor control cabinets are eliminated. Reduced need for wiring long screened motor cables.
VLT® DriveMotor FCM 300
The VLT FCM 300 Series is a very compact alternative to the traditional solution with a VLT frequency converter and motor as separate units.

The frequency converter is attached in place of the motor terminal box. It is not higher than the standard terminal box - not wider nor longer than the motor.               
MCD 200 Series Soft Starters

Due to extensive use of the latest technology, such as new semiconductor control algorithms and bypass design, the new soft starters are very compact and heat dissipation very low.

There is no need for extra ventilation or bypass contactors. This simplifies installation and keeps panel space at a minimum.

MCD 201 is the basic version offering timed voltage ramps.

MCD 202 is the advanced version providing current limit soft start, timed voltage ramp down, and motor protection.               

V-Series S2E/S2T - Small Powerful Modular PLC's

Toshiba PLC's are manufactured by Toshiba using Toshiba's own advanced processors and memory.  Because of this a significant cost savings can be realized.  Toshiba does not charge for Tech Support unlike some of the big marketing (but not manufacturing) companies.  You owe it to yourself to check Toshiba on your next PLC project. 
OIS's, Touch Screens

Toshiba's unique and cost saving OIS's and Touch Screens come in many configurations for fit and function.  Built in I/O and PLC's are often all that you will need.  Give us a call to check the possibilities for your next project.
