Braking Resistors Ohm-A and Ohm-B
The DC-bus capacitors of inverters can only partially absorb regenerative energy and must be guided from the system to the outside. KEB COMBIVERT are available with internal brake transistors (GTR7), which transmit "excess" energy to external resistors.
The OHM-A and OHM-B resistors offer high pulse capacity at a small installation space and
- feature thermal monitoring through break contacts (series feature)
- work without additional noise during braking
Available as
- universal ancillary components Ohm-A and Ohm-B for high pulse performance and
- compact substructure module for absorbing smaller pulse energies.
Universally prepared for global use and UL/ cUL approved.
