The 1336F-BRF100-AJ-DE model represents an advanced AC variable-frequency drive converter within the Allen Bradley 1336 PLUS II lineup. Designed for 380 to 480 VAC three-phase input, it is engineered to manage demanding motor applications. This drive achieves a nominal DC bus voltage of 648 V, ensuring stable operation under various conditions. With a maximum input current rating of 82 A, it is capable of delivering motor output currents of 68 A under constant torque or up to 85 A with variable torque.
This unit also boasts an IP 54 rating, offering significant protection suitable for a variety of environments, aligning with NEMA 12 standards. Under intermittent overloads, it can tolerate up to 150% of rated current for constant torque and 115% for variable torque, each sustained for one minute. Its input voltage can tolerate variations from -10% to +10% of the nominal, while the frequency tolerance allows operation between 48 Hz and 62 Hz.
The drive maintains a displacement power factor of 0.95 when using a standard inductor, contributing to its efficient performance, which attains an efficiency of at least 97.5% at rated conditions. Users can program the carrier frequency across a range from 2 kHz to 8 kHz, which provides flexibility in application settings. The device offers advanced acceleration/deceleration controls with two independent ramps, adjustable from 0.1 to 3600 seconds.
Moreover, the 1336F-BRF100-AJ-DE features a minimum logic ride-through capability of 0.5 seconds, typically allowing for 2 seconds of uninterrupted control, effectively managing transient disturbances. For communication, it includes a standard serial interface compatible with RS232, RS422, and RS485, supporting DF1 and DH485 protocols, making it adaptable for integration within various control systems.
