20GE4GD248JN0NNNNN

The Allen-Bradley 20GE4GD248JN0NNNNN motor control drive is a digital AC and DC-powered drive. It belongs to the Allen-Bradley PowerFlex 755TS series of industrial drives. The drive’s frame size is Size 7. It is meant to be mounted on a flat vertical surface. The cooling method employed is forced air cooling. For this drive, the minimum required airflow is 756 cubic feet per minute or 1284.45 cubic meters per hour. The provision of this minimum airflow will help to ensure that the ambient temperature stays within the recommended limits. The recommended ambient temperature range for the 20GE4GD248JN0NNNNN drive is -20 to 40 degrees Celsius. The output of the 20GE4GD248JN0NNNNN drive will derate if the temperature goes above 40 degrees Celsius. As per the recommendations from Allen-Bradley, the maximum permitted temperature for safe drive operation with output derating is 50 degrees Celsius.

The input of the Allen-Bradley 20GE4GD248JN0NNNNN PowerFlex 755TS series motor control drive is compatible with 3-phase AC power supplies that can provide it with 480 Volts AC of input voltage. With the rated input, the continuous drive output rating is 248 Amps. The 20GE4GD248JN0NNNNN drive supports 2 working modes: the normal duty mode and the heavy-duty mode. The drive output in the normal duty mode is 200 Horsepower. The drive output rating for the heavy-duty mode is 150 Horsepower. The NEMA Type 12 rated drive housing supports an “XT” level of corrosive gas protection. The environmental protection rating of the 20GE4GD248JN0NNNNN drive is IP 54. Two integrated Gigabit Ethernet communication ports are available on the 20GE4GD248JN0NNNNN drive. These 2 ports allow the use of 3 topologies for network communication, and these are the star, linear, and ring topologies. The major benefit of the ring topology is redundancy, which means that network communication can continue even if a network node gets disabled or if a single Ethernet cable is damaged.
