M3645

The M3645 Line Regen is the latest release of Digital Line Regeneration Braking solutions from Bonitron. The M3645 Series replaces the legendary M3345 Series, but continues its legacy with additional features, simplicity, and reliability.

When variable speed drive systems are braking, they generate power that must be dissipated. If the excess energy is not dissipated, the drive system can lose control of the process due to an overvoltage trip, or must extend the braking time to keep from overpowering the drive.

There are two common methods of dissipating excess energy. The traditional method involves a resistor, but resistors take up a significant amount of space and produce an abundance of heat, making them impractical to integrate into a drive cabinet. The better solution for most applications is the M3645 Digital Line Regen. Instead of dissipating the excess energy as heat in a resistor, the M3645 returns this energy to the power grid efficiently, with minimal heat loss, allowing the entire braking system to be installed in the drive cabinet. This reduces installation footprint and facility cooling costs.

The M3645 offers an interactive digital display that allows quick access to current, voltage, status logs, and energy monitoring data.

*Note that the M3645F includes fuses and fuse holders

In order to maximize value, the M3645 Line Regen does not have internal fusing. Such fusing can be supplied locally (consult for sizing) or you can purchase an M3645F that installs easily with the M3645 Digital Line Regen. See the tables on this page to determine which fuses are used with your M3645 Digital Line Regen, or review the M3645F User Manual, which is linked to the right.
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.
