¨ 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

The motor start and braking device of the VersiComb series from PETER electronic, for motor ratings up to 15KW, represents an alternative with a good cost-performance ratio in order to replace star-delta starting in combination with a d.c. braking device.
The devices of the VersiComb II type enable soft start and wear-free braking of three-phase asynchronous motors. Their advantages in comparison with direct-on-line starting or star-delta starting are a torque increase without jerk and current reduction during the starting phase.
This gives the mechanical system and the drive components a longer life.
