The 1336F-B400-AN-DE-CM by Allen Bradley represents a sophisticated AC variable-frequency drive with substantial capabilities tailored for industrial use. Supporting a continuous power output of 298 kW, equivalent to 400 horsepower, this drive functions effectively within the input voltage spectrum of 380 to 480 VAC. Constant output current ratings reach up to 475 A, while the drive accepts 471 A in constant-torque applications.
The apparent power capabilities range from 310 to 392 kVA, enabling adaptable performance for various operational needs. The DC bus operates at a nominal voltage of 648 V DC, ensuring strong performance in applications requiring higher voltage levels. Moreover, the PWM carrier frequency is programmable between 2 kHz and 6 kHz, delivering precise control through sine-coded PWM modulation.
For operational safety, the AC input overvoltage threshold is set at 570 VAC, while the undervoltage threshold is set at 280 VAC, providing reliable limits for safe operation. An integrated common-mode choke enhances the drive's noise immunity during operation.
Ingress protection is rated at IP00, indicating that while the unit is not sealed against dust or moisture, it is suitable for indoor environments. With an operating temperature range from 0 to 50 °C, it can adapt to typical industrial conditions. Additionally, this drive has significant intermittent overload capabilities, handling up to 150% of constant torque and 115% of variable torque for brief durations of up to one minute.
