Equi-Vec: Balanced Vector Control

Typical 2-Phase control waveform

Balanced Vector Control

In the past soft starters using two phase control caused extra heating in the motor and required higher starting currents because the output waveform was not symmetrical.

CSX soft starters control only two phases, but include Equi-Vec™ balanced vector control technology. Equi-Vec™ balances the output waveform to make it symmetrical. By balancing the waveform the CSX provides 3 phase like performance with compact soft starter technology.

This eliminates previous limitations of two phase controllers such as:

  • Limited starts per hour
  • Limited to light loads only
  • Limited to motor < 55 kW



Trip messages

The CSX series allows for fast diagnosis of a trip via two LEDs on the front of the unit. LEDs will flash to indicate the trip. (Note: some trip messages available only on the CSXi or with an optional accessory).
