    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.
