1336F-A025-AN-EN

The Allen Bradley 1336F-A025-AN-EN is a variable-frequency drive (VFD), suitable for various motor control tasks. With a nominal input voltage specification of 200–240 V AC, this drive allows for input voltage fluctuations of up to ±10%. It operates within a supply frequency range of 48 to 62 Hz. At the heart of its functionality is a rated output current of 77 A, which supports both a constant-torque output power of 18.5 kW, equivalent to 25 HP, and a variable-torque power rating of 25 HP. The drive is designed with an open construction (IP00 rating), making it more suitable for environments where dust and moisture are not significant concerns. It features trip thresholds that help protect against extreme conditions: an overvoltage threshold of 285 VAC for AC input and a 405 V DC threshold for the DC bus; the undervoltage trip levels are set at 138 VAC for AC input and 200 V DC for the DC bus. Modulation is achieved through sine-coded PWM with a programmable carrier frequency adjustable between 2 and 10 kHz, enabling versatility in operation modes. Power ride-through capabilities ensure stable performance even during brief interruptions, with a 15 ms hold time at full load. The operational temperature range spans from 0°C to 50°C, enabling it to function effectively in typical ambient conditions. Additionally, the unit may be installed at altitudes of up to 1000 meters (3300 feet) without any derating of its performance, making it adaptable for various installation environments.
