Braking device KIMO

¨ Rapid braking of three-phase induction motors fed by frequency inverters without an integrated braking chopper

¨ Elimination of production stops due to unwanted inverter tripping caused by overvoltage in the DC link

Applications

Braking of three-phase drives fed from frequency inverters,
in particular:

¨ Drives with a large inertia, e.g. large fans, centrifuges

¨ Drives with requirement for rapid braking, e.g. saws, planing and milling machines

¨ Drives for transport, long travel and hoisting applications

¨ Retrofit to existing inverters without a braking chopper e.g. to avoid nuisance tripping with link overvoltage.

¨ Often a price advantage compared to braking choppers of original inverter manufacturer

Features

¨ Compatible with all frequency inverters with a DC voltage link operating at input voltages up to 3 AC 690 V

¨ Simple wiring without control voltage - only two cables to the DC link required

¨ Integrated braking resistor with TRANSOMIK B

¨ External braking resistors with overtemperature protection (OPTION BR) with TRANSOMIK BC

¨ Adjustable brake threshold-voltage;
- TRANSOMIK B: • Factory adjustable
- TRANSOMIK BC: • Switchable preset values

¨ TRANSOMIK BC is especially suitable for quasi- continuous braking duty (e.g. heavy-duty braking for crane drives)

¨ Special monitoring functions with TRANSOMIK BC:
- Heat sink overtemperature trip
- Additional with TRANSOMIK BC2:
- Monitoring LED's
• Electronic overload-monitoring of brake resistor
• Fault latch with relay output

¨ TRANSOMIK BC2 can be paralleled for higher braking powers
