The Allen Bradley 1336F-B030-AJ-IT is an adjustable-frequency drive engineered for diverse industrial operations. It efficiently produces an output power of 22 kW (30 HP). The drive remains flexible for various setups with a supply voltage range from 380 to 480 VAC and a tolerance level of -10% to +10%. The device ensures dependable performance, with an input frequency tolerance between 48 Hz and 62 Hz.
The drive's output frequency capabilities range from 0 Hz to 400 Hz, allowing it to suit multiple applications. It is designed to handle maximum output voltage from 0 V to the rated line voltage. The sine-wave pulse-width modulation method is utilized for modulation, providing options for user-defined carrier frequencies. This flexibility enhances the unit's adaptability in different operational scenarios.
Accuracy in frequency response is notable, with a precision of ±0.01% for digital commands and ±0.4% for analog commands. To safeguard against electrical issues, the drive includes an overvoltage trip point set at 570 VAC and an undervoltage trip threshold at 280 VAC.
Current limiting is also included, with software limits set at 20–160% of the voltage transformer rating, hardware limits of 180–250%, and instantaneous limits ranging from 220–300%. The drive maintains consistent operation, with ride-through capability of 15 ms for power at full load and logic typically lasting 2 seconds or more.
An operating ambient temperature range of 0 °C to 40 °C is supported, shielded by an IP54/NEMA Type 12 enclosure that offers ample protection. Thermal overload protection is implemented through a heat-sink thermistor monitored by a microprocessor, ensuring the drive can shut down when overheating occurs. This design makes the 1336F-B030-AJ-IT a reliable choice for various industrial applications.
