The 20AD034A3AYNARNN from Allen Bradley is part of the PowerFlex 70 series. This adjustable-frequency AC drive is tailored for 480 VAC operation with a three-phase, six-pulse configuration at 50 Hz.
The device can deliver output ratings of 25 horsepower (18.5 kW) for normal-duty applications and supports up to 20 HP under heavy-duty conditions. Its rated line current stands at 34 amperes. An integrated dynamic brake transistor (IGBT) enhances functionality without including an internal braking resistor. Connection capabilities are facilitated through a DPI (Drive Peripheral Interface) for remote I/O applications.
This drive is designed for panel mounting and features a human-machine interface with a user-friendly LCD and a full numeric keypad for ease of operation. The drive relies on a standard open-loop V/Hz control scheme and does not support feedback systems with encoders, limiting its use to applications where closed-loop control is unnecessary. With a frame size designation of Frame D and an IP20 enclosure rating, it is protected against certain environmental factors, making it suitable for controlled industrial environments.
