The 20AD027A2AYNARNN AC drive unit from Allen Bradley is built for efficiency in a three-phase system, operating at 480 VAC input. This drive is designed to accommodate a current capacity of 27 Amps, delivering up to 20 horsepower for normal-duty and 15 horsepower for heavy-duty tasks.
Installation is facilitated through a panel-mounted configuration, and it is enclosed in an IP20-rated case compliant with NEMA Type 1, suitable for controlled environments. An integrated LCD screen provides users with a straightforward interface, complemented by a digital keypad for easy configuration and adjustments. The built-in IGBT braking module supports effective braking capabilities, but note that an external braking resistor is not installed in this unit by default.
The drive is CE EMC-certified, ensuring compliance with Directive 89/336/EEC, which signifies its reliable performance in electromagnetic environments. Communication with other devices is achievable through a remote I/O connection using a DPI module. Adopting a standard control architecture, the unit operates with open-loop feedback, which means it does not include integrated feedback systems.
