M3545P

Regenerative DC Bus Power Supply (5 - 15A)

M3545P Regenerative DC Bus Power Supply

The M3545P Regenerative DC Power Supply is a bi-directional power supply. Under motoring conditions, the M3545P rectifies the AC line and supplies power to the drive through its DC bus terminals. If the DC bus voltage begins to rise, due to the drive trying to brake or an overhauling load, the M3545P will sink energy back to the AC Line.

Alternative resistive braking solutions simply dissipate this regenerated energy as heat. Bonitron’s M3545P returns the regenerated energy back to the AC line, making it particularly well suited for applications with frequent or extended duration braking events. Additionally, the M3545P is designed to be able to operate on both single-phase and three-phase AC grids, at either 50Hz or 60Hz line frequency.

Savings

Bonitron Line Regen units return regenerative energy back to the AC line where it can used by equipment within the facility. This reduces the amount of power required from the utility; reducing utility costs. The formula to the right is an example for a 100HP application. Visit Bonitron.com/RegenCalculator to see your potential savings.

The calculator does not include the cost of the Line Regen itself. Contact Bonitron for pricing and to discuss your application. When comparing a Line Regen to a Resistor, consider the added cost of wiring, conduit, or cooling for a resistor. While many resistors produce enough heat that they need to be located outside, Bonitron Line Regens are 99% efficient and are designed to be integrated into the drive cabinet.

Note: This calculator is for illustration purposes. Contact Bonitron to discuss your application and savings.
