SD1 - AC Variable Speed Inverter Drives

 

The SD1 range of AC Inverter Drives is the ultimate variable speed drive for you! Easy to set up and comprehensively specified for use in virtually any application, the SD1 is IMO's first complete range of variable speed inverter drives which offer STO (SIL2 / SIL3 dependent upon model), along with a huge range of enhanced features, normally found on much more expensive inverter drives.


What is an AC Variable Speed Inverter Drive?

Whether you call it an AC Variable Speed Inverter Drive, a Variable Frequency Drive, a Variable Speed Drive, Micro Drive, or just an AC Inverter, it is a type of adjustable speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage. AC Variable Speed Inverter Drives are used in applications ranging from small appliances to large industrial compressors. About 25% of the world's electrical energy is consumed by electric motors in industrial applications, which can be considerably more efficient when used in conjunction with an AC Variable Speed Inverter Drive, saving both energy and money.


Why the SD1?

When selecting an AC inverter, two important factors are performance and price. Performance because you need to ensure your inverter can cope with the most arduous applications, and price because AC inverters are often about saving energy and a short pay-back time on capital expenditure is key. The SD1 delivers on both these counts.


SD1 Features

The SD1 range is suitable for virtually every industrial application, made possible by a range of EMC filter options. Additional to the filters, the SD1 offers as standard:

  • IP20
  • STO (Safe Torque OFF)
  • HDI Input (Pulse)
  • PID Control
  • Motor Auto-tune
  • Torque Vector Controls
  • Up to 150% Starting Torque
  • Integral Modbus-RTU / RS485
  • DC Injection Braking
  • 2 Year Warranty



Enhanced Control Functionality

As you would expect, a drive from IMO isn't your average run-of-the-mill product. We produce solutions which tick every box, every time, and the SD1 is no different. From offering motor auto-tune which minimises power losses, to PID control which allows motor operation whilst controlling temperature, pressure and flow rate without the need for an external device or controller, together with the inclusion of programmable logic functionality, the SD1 is so packed with features that you wouldn't believe they fit inside its compact and user-friendly form.


Connected for Communications

Every model in the SD1 range offers communication capability. The connection is completed by way of twisted-pair to the dedicated RS-485 terminals found on the control terminal block. Communications are carried out using the Modbus-RTU protocol.
