Dynamic brake section

The dynamic brake section (DBS) includes the largest NXI drives from the VACON

NXP product

series. The brake units are all VACON

NXP premium drives.

As standard the DBS section includes the following:

1. Input fuses (DC fuses)
2. The NXI brake chopper
3. Service platform/module removal
4. Control section and fixed external terminals, 70 pcs

As pre-engineered standard options we can provide the following:

• Input Switch (with charging) (+ISC)
• Input Switch (DC-disconnect) (+ISD)
• Arc detection (+ADU)
• Top cabling (+COT)
• UL approved design and components (+NAR)
• Cabinet heater (+ACH)
• Cabinet light (+ACL)

The dynamic brake sections are similar to the inverter unit sections. See the dimensions and
example figures in Chapter 3.5.2.
