20G14NB477JA0NNNNN

The Allen Bradley 20G14NB477JA0NNNNN is an AC drive engineered to meet high industrial demands. The device supports a DC input type combined with precharge functionality, optimizing performance and reliability. Operating at a voltage rating of 240 VAC (with a minimum of 208 VAC) and 325 VDC (minimum of 281 VDC), it showcases versatility in various application settings.

With a current capacity rated at 477 amps, this unit provides substantial power output, reaching up to 200 horsepower (equivalent to 150 kW). Its robust frame size is configured at 700%, allowing it to accommodate significant operational loads. This drive is appropriately housed in an NEMA-rated enclosure (IP00, IP20, NEMA Open, and NEMA 1), ensuring environmental protection.

Designed to operate efficiently within a temperature range of 0 to 50 °C (32 to 122 °F), the drive can withstand storage conditions as low as -40 °C and up to 70 °C (-40 to 158 °F). The unit features an internal transistor for dynamic braking, enhancing stopping capabilities in applications requiring rapid deceleration. A default configuration for the common mode capacitor is provided with a jumper already installed, simplifying setup and installation processes. Although there is no door-mounted Human Interface Module (HIM), the drive integrates filtering mechanisms ensuring stable performance across various operating conditions.
