Bonitron M3500DB Dynamic Safety Brake

Bonitron > Products > Overvoltage > Dynamic Braking > M3500DB

The M3500DB Series enhances system performance and safety by providing resistive braking control for emergency stop applications if regenerative braking does not perform.

The M3500DB Series satisfies the need to physically isolate one motor from its drive so that the axis module is in a safe condition for an operator to intervene in a process.
