All Braking Resistors & Braking Units Use in AC Drives
Note: Please only use DELTA resistors and recommended values. Other
resistors and values will void Delta’s warranty. Please contact your nearest Delta
representative for use of special resistors. For instance, in 460 V series, 100 HP,
AC drive has 2 braking units with total of 16 braking resistors, so each braking
unit uses 8 braking resistors. There should be at least 10 cm away from AC drive
to avoid possible noise. Refer to the “Braking Unit Module User Manual” for
further detail.
