1336F-BRF200-AJ-EN-HJ2

The 1336F-BRF200-AJ-EN-HJ2 by Allen Bradley operates as an advanced AC variable frequency drive (VFD). This drive presents an impressive rated input voltage range, compatible with both 380-480 VAC and 513-620 VDC systems. For performance, it delivers a CT output rated at 27 Amps when handling 22 kVA, with an input capacity of 28 Amps operating within an 18-23 kVA range. The motor capability aligns at 15 kW, translating to 20 horsepower, making it suitable for various industrial tasks.

Designed with user interaction in mind, the drive features a human-machine interface (HMI) consisting of a programmer/controller and a digital potentiometer, both rated at IP65/54. The enclosure offers IP54 (NEMA 12) protection, ensuring suitability for moderate environmental exposure.

For overload management, the system handles 150% of current for 1 minute in CT mode and 115% for the same duration in VT mode. The control method utilizes sine PWM with a programmable carrier, allowing for fine-tuned performance. This device achieves an output frequency range from 0 to 400 Hz, accommodating a variety of motor speeds.

Acceleration and deceleration can be programmed over a span of 0 to 3600 seconds, with adjustability in 0.1-second intervals, enabling a tailored response for start-up and stopping sequences, with support for two distinct ramps. Current limiting can be set between 20-160% of the rated value, with separate pressure and integral controls.

The system’s ride-through capability ensures that power remains stable for 15 milliseconds under full load, with logical operations lasting between 0.5 to 2 seconds in the event of a power interruption. Protection measures include a thermistor for monitoring over-temperature, along with safeguards against output ground faults and short circuits, preserving the integrity of both the drive and the connected motor.
