20G1ANB477JA0NNNNN

The 20G1ANB477JA0NNNNN, part of Allen Bradley’s PowerFlex 755 lineup, serves as an efficient AC drive. Operating on an AC input supply, this unit features a precharge capability with no DC terminals, broadening its use in various configurations. This drive is rated for a voltage class of 240 VAC (with acceptable operation at 208 VAC) and can handle 325 VDC (with a minimum of 281 VDC). With a current handling capacity of 477 amps, it is adept at managing large power demands. The drive delivers considerable power output—200 horsepower (150 kW)—making it well-suited for extensive applications.

The frequency specification allows operation within both 50 Hz and 60 Hz environments, enhancing its adaptability to different systems. The internal cabinet is classified as IP00, IP20, and NEMA 1, offering protection suitable for indoor applications. This unit features an internal filtering mechanism and has a jumper installed for the common mode capacitor to facilitate ease of setup and maintenance. Additionally, it employs an internal transistor for dynamic braking, which aids in controlling motor speed and providing effective stops. It does not include a door-mounted Human Interface Module (HIM).

In terms of temperature range, the system operates smoothly between 0 to 50 °C (32 to 122 °F) and can be stored in conditions ranging from -40 to 70 °C (-40 to 158 °F). This extensive temperature tolerance makes it a reliable choice for operations in various environmental conditions.
