*Required fields.



  • Seamless power transfer from utility to Bonitron
  • Maintain process while generators start up
  • Full-load power for up to 2 seconds for 50% 3-phase sags or 1-phase sag to 0 V


  • Low-Voltage Power Supply)
    • Isolated 28V 250-amp battery charger
    • 700-1000 VDC input to car from catenary
  • Boost from 24V battery string to operate drives during outage
  • Relatively low power (7kW), very specific application


  • Large prototype for Galco
    • 1000 ADC 1000 VDC bidirectional buck-boost
    • Battery simulator

M3452 Series

  • Braking Resistors
  • Braking Transistors
  • Single Phase Power Supplies
  • Line Regeneration Modules
  • Uninterruptible Power for Drives


M3645 & M3545

  • The Bonitron Line Regen is efficient and small enough to be integrated into the drive cabinet. This eliminates excess resistor wiring and cooling costs.


  • Simple, Passive method for storing regenerated energy from a braking motor
  • Allows for an increase in energy storage with a smaller rise in DC bus voltage when used conjunction with a capacitor bank and various external components
  • Stored energy can be sourced back to the DC bus during periods of higher demand, lowering the peak power required by the system


  • Input Voltage 24 VDC
  • System load bank 3x 2.7 ohm, Wye connected
  • System Voltage 900VDC Nominal
  • Peak Current 1800ADC


  • Replacment for Rockwell1398-PSM-125C power supply according to Universal Studios' specs
  • 230VAC three-phase input, 100 ADC output
  • Integrated braking transistor
