2.1.1.1 Power element
Power element 2- Ueber_Merkmale_Leistungsteil_protego_D_48_und_72
The servo amplifier's power element has the following features:
 Connection to earthed three-phase supplies, rated voltage range
208 V – 480 V
 TN network and TT network with earthed star point, max. 42 kA sym-
metrical rated current, connection to other networks only with isolat-
ing transformer
 B6 rectifier bridge integrated directly on the three-phase, earthed net-
work, mains filter and start-up circuit
 Fuse protection (e.g. blow-out fuse) through user
 All shield connections directly on the servo amplifier
 Max. intermediate circuit voltage in generator mode: 260 – 900 VDC,
can be connected in parallel
 Brake chopper, brake power distributed over several amplifiers on the
same intermediate circuit
 No internal brake resistor, external brake resistor available on re-
quest.
 Inverted rectifier with isolated current measurement and IGBT transis-
tors
 Connection of synchronous servo motors, linear motors, asynchro-
nous motors
