VFD DC Bus Solutions

The Bonitron M7009C is an extension to the M7009R, offering more hold-up time as well as increased outage duration. With the M7009R, you can have confidence that your controls, relays, and other 24V loads will continue to operate during most outages...

Bonitron M7009R is a cost-effective solution for protecting your 24-volt DC bus from short-duration sags and outages. During normal operation, the unit trickle charges from the 24V bus, fully charging in under six minutes, with a peak charge current of 1...

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...

As electrolytic capacitors' age approach end-of-life, their capacitance drops significantly below their original specification. These capacitors typically need replacement to avoid process failure. Measuring the actual capacitance helps determine when...

When variable frequency drives are stored for long periods (typically over eight months), the internal chemistry of their capacitors may begin to deteriorate and need to be reformed prior to use. If the capacitors are not reformed before the drive is put...
