1336E-B025-AN-EN

The 1336E-B025-AN-EN, part of the 1336 IMPACT Drives series from Allen Bradley, is engineered to function as an adjustable frequency AC drive. It is designed explicitly for three-phase systems and operates effectively within an input voltage spectrum of 380 to 480 VAC, allowing for deviations from nominal values of up to +10% or down to -15%. The rated power of this drive is noted at 25 horsepower, which converts to approximately 18.5 kilowatts.

In terms of electrical characteristics, this unit operates with an input kVA rating that fluctuates between 23 and 26 kVA. It requires an input current of 43 Amps, thus ensuring adequate power delivery for various industrial applications. On the output side, this drive achieves a kVA rating of 33, with a continuous output current of 41.8 Amps.

The input frequency is typically set to either 50 or 60 Hz, with an allowable variance of ±3 Hz. Users can take advantage of an extensive output frequency range of 0 to 250 Hz. The output waveform is of the PWM sinusoidal variety, enabling smooth operation. Efficiency is high, with a typical benchmark at 97%, indicating low operational losses.

For dynamic performance, the drive maintains speed regulation within ±0.5% accuracy when operating encoderless, while torque regulation characteristics present ±5% accuracy without an encoder and ±2% accuracy when utilizing one. Additionally, the drive demonstrates robust overload handling capabilities, rated at 150% for one minute, making it resilient for heavy transient loads.
