l
Shielding All shielding connections are made directly on the amplifier
l
Output stage IGBT module with floating current measurement
l
Brake circuit with dynamic distribution of the generated power between
several amplifiers on the same DC bus link circuit. Internal
brake resistor as standard, external brake resistors if required.
l
DC bus link voltage 135...900 V DC, can be connected in parallel.
l
Interference suppression filters are integrated for the electrical supply feed and the
24V auxiliary supply voltage (with motor cable £ 10m for C2 as per IEC 61800-3, with
motor cable > 10m for C3 as per IEC 61800-3).
