Less power for intelligent motor controls—more power to users

The key to this advance is a new design that separates control and logic circuits to cut power requirements and focuses exclusively on low control voltage at 24 V dc.Emergence of 24 V dc control has been ongoing, but mainly driven by low-amperage applications.
