INVDxx AC Motor Inverter Drives from Cognito Quam Electrotechnologies Ltd.

Our fully protected, programmable and network-ready INVD inverter drive is a versatile building block in single and multiple AC motor control applications.

The INVDxx inverter drives interface with most (if not all) automation equipment in the market as well as all Quamatic hardware.  They are versatile mechanical interfaces in many applications and are fully protected, network-ready, digitally-controlled, fully-programmable units.  They are simple to install and are effectively employed in speed control applications driving:

  • Transport systems (conveyors, escalators, roller tables etc.),
  • Pumps and compressors,
  • Transmissions (gear trains, high-ratio belt systems etc.),
  • Fans and ventilators, and
  • Mixers

Main features of the line include:

  • Four types with 3phase, 5 - 40 HP (3.7 - 30 kW), 400-440 VAC nominal power capability.  Models below 5HP and above 40HP are available on special request,
  • Soft starting DC-link charge-up to minimize capacitor inrush currents,
  • Fully protected, robust operation,
  • Output dV/dt filter to protect the load, its insulation and to minimize noise,
  • Versatile, multimode isolated universal connection 24 VDC control input and output interface,
  • Dual standard serial port (EIA-232 and EIA-485),
  • Full parameter programmability via the serial port,
  • Local unregulated supply (24 VDC) to power the control interface, small sensors, solid-state relays and other small automation devices,
  • Optional resistor brake kit,
  • Easily accessible power and removable control connectors, and
  • On the fly change of rotational direction.
