Variable Speed Drives

For starting, running and controlling Electric Motors ….


We highly recommend you replace your Star Delta Starters and/or Direct Online Starters, with ABB Variable Speed Drives. For new installations we really feel this is the way to go, for the following reasons:

  •  Soft Start feature from Zero Amps to never more than 1 x FLC (Full Load Current), unless required. Star Deltas require up to 3.3 x FLC to start and Direct Online’s 5 x FLC
  • Only half (if not one third) size generator/solar farm/hybrid system needed to start up and run a motor with a Variable Speed Drive (VSD), as opposed to with an Auto Star Delta (ASD) or Direct Online (DOL)
  • Power Factor Correction feature included, saving you money via your electricity bill
  • Uninterrupted Power Supply feature included (short term which assists during brief power supply dips)
  • Only necessary KW Hours consumed, saving you money via your electricity bill
  • Voltage Stabilization feature included (to surprising effect)
  • With Automation Pack (included in our prices) startups are automatic (if selected), therefore saving time (maximizing water on crop etc.) by eliminating the human element of pressing start buttons
