With a unique combination of features, performance and size, Motortronics has redefined the benchmark for soft starter design.

The incorporation of Motortronics’ unique iERS technology allows VMX-synergy™ to deliver unrivalled soft start performance alongside energy saving capability on partially loaded motors.

With product size and cabinet capacity becoming an increasing focus we developed VMX-synergy™ to deliver the greatest power to size ratio of any other soft starter.

In addition VMX-synergy™ uses Motortronics’ globally renowned Automatic Setup feature which allows the user to programme the unit to any common application using a simple 4 step process. To keep pace with the modern technology, VMX-synergy™ removes the need for buttons and uses intuitive touch screen technology.

With built in full motor overload protection as well as full data logging, field serviceable fans, upgradeable firmware and extensive input/output programmability, VMX-synergy™ meets all of the key design criteria.

Features & Benefits
  • Ease of Use: The display will show all messages in full and 14 different global languages. The use of graphic/schematic images will facilitate complete understanding. Detailed logging will aid setup and onboard USB will allow configurations to be upload/downloaded and emailed.
  • Touch Screen: Colour Touch screen on all versions.
  • Plug n Play: The soft starter will ‘tune’ itself to the load.
  • Auto Set Up: The automatic functionality has been expanded so that more features can be configured without referring to parameter lists.
  • Optimising: Energy optimising is combined with bypass to give energy saving in more applications.
  • Serviceability: Field replaceable fans.
  • 2 Year Warranty: This is made economically viable by the comprehensive logging features, so fault conditions can be easily identified.
VMX – synergy™ – Redefining Soft Starters
Variable Speed Drives are not needed in all applications, with fixed speed loads, a soft starter is a better as well as more economical solution.
