Smart-Boost™ Digital Rotary Phase Converter

The Smart-Boost is a new breed of Digital Rotary Phase Converter. Our Smart-Boost technology aids in the startup of motors external of the phase converter downstream. The Smart-Boost Controller uses solid state switching to re-engaging the start capacitors at zero degree crossing. Which in turn, surges 600% more current to the motors during their startup.

Motor Load Chart

Smart-Boost Quick Sizing Rules

*For light & medium motor loads:
-Choose the converter that is closest to the total HP of your 3 phase machines.
*For hard & very hard motor loads:
-Choose the converter that is 1.5 times or double the size of your horsepower.

Sizing note: The Smart-Boost Rotary Phase Converter will start motors of equal size, we recommend oversizing the phase converter for hard and very hard loads to maintain better voltage balance.

Smart-Boost Digital Controller
  • Electronic Solid State Switching (no contacts)
  • 120 Degree Pure Sine Wave
  • Zero Degree Capacitor Switching
  • Self-Protected Power Semi Conductors - SCR
  • Voltage Differential Technology
600% Motor Starting Boost Current
  • Provides high starting current for hard starting / high inertia loads
  • Active when digital rotary phase converter starts and for every external motor start
  • Allows for flying restarts
  • Synchronization of capacitors voltage when reconnecting start
Built-In Motor Starter
  • Integrated magnetic motor starter complete with on/off switch
  • Power "On" indicating light lets you know the phase converter is on from across the room
  • Raised off bottom for quick shut downs
Power/Phase Protection
  • Disconnects all 3 output lines from the phase converter (not just the manufactured line)
  • Shuts down the phase converter in the event of power outage (blackout)
  • Protects your motors and equipment from "single-phasing" when power is restored
Easy Installation
  • Large wiring compartment
  • Removable sub panel design makes the enclosure light and easy to mount
  • Over-sized power distribution blocks are well marked and easily accessible
  • Punch out "Knock-Outs" on all 4 sides of the enclosure
Important Extras
  • Oil and epoxy filled capacitors - no limit on the number of motor startups and can stay energized for long periods of time
  • High current protective coils - provides a layer of protection against voltage surges & fast transient short circuits
  • Large bleed resistors for extended capacitor life
  • Made in the USA by a UL 508A Certified Panel Builder located in Wisconsin
Custom designed Phase Converter Generator by Baldor USA
  • Built in America by Baldor USA
  • Built and designed to work with our Smart-Boost Controllers and as a phase converter
  • High Speed / Low Impedance Design - promotes a strong manufactured leg of power
  • Custom laminated winding design provides feedback to the Smart-Boost Controller
