Appendix
Low Voltage Field Module
Magnetek offers two version of the Field Module for Quattro™ DC. This document
details the appropriate use of each module.
The Low Voltage Field Module is recommended for applications with:
o 380-480 VAC 3-phase input to drive or 200-240 VAC 3-phase input to drive
when Field Current is less than 20 Amps
o Lower peak to peak and ground voltage on field when using higher input
voltage
The Standard Field Module is recommended for applications with:
o 200-480 VAC 3-phase input to drive where insulation stress is not a factor
o Applications that exceed output voltage/current rating of Low Voltage Field
