PowerFlex Common Bus
PowerFlex® 20T Bus Supply for Common DC Bus Applications
The PowerFlex Diode Bus Supply is a non-regenerative DC bus supply used to supply power to a line-up of AC drives with common DC bus input. The supply converts incoming three-phase AC line voltage to a common DC bus voltage.
Bulletin 20T Diode Bus Supply offers the following features:
- Six-pulse, full-wave, three-phase diode bridge rectifier unit.
- Integral DC chokes, input filter capacitors and common mode capacitors compose an RFI filter meeting the requirements of EMC product standard 61800-3 for industrial environments.
- Bus supply over temperature sensors located in the heat sink for thermal protection of the diode bridge rectifier.
- DC bus snubber circuit for dampening and linearity of over voltages.
Ideal for the following applications:
- Paper Making Machines, Finishing Winders, Calendars, and Rereelers
- Metal Rolling Mills, and Slitters
- Winders, Coaters, and Calendars
- Cranes
