20G11GB054JA0NNNNN

The Allen Bradley model 20G11GB054JA0NNNNN is designed for versatility and durability as an AC drive. Operating on an input voltage range of 240 VAC (with a possible option of 208 VAC) and a corresponding DC voltage rating of 325 VDC (281 VDC for lower operations), it ensures compatibility across various applications. The unit can handle a line frequency of either 50 Hz or 60 Hz, making it adaptable to different regional standards.

At a power output of 20 horsepower or 15 kilowatts, this drive provides a nominal current rating of 54 Amps, equipping it for handling significant load demands. Designed as a frame size 4 unit, it features a robust enclosure with an IP54 rating, aligned with NEMA 12 standards for dust and moisture protection. For efficient operational capability, filtering is included, while the precharge feature with installed DC terminals promotes effective integration with other systems.

Dynamic braking is also facilitated through an internal transistor, which provides enhanced stopping capabilities without the need for external components. While lacking a door-mounted human-machine interface, this drive’s design supports seamless control and monitoring through other means. The operating temperature range is specified between 0 to 50 °C (32 to 122 °F), and it can reliably store within a temperature span of -40 to 70 °C (-40 to 158 °F), ensuring its functionality amidst various environmental conditions.
