The 20DD248A0EYNAEASE AC drive manufactured by Allen Bradley is engineered for demanding industrial applications, delivering a substantial output power of 150 kW (200 HP) with a maximum current output of 248 A. The unit is configured for a rated input voltage of 480 VAC and adopts a 3-phase, 6-pulse input phase configuration. Its enclosure offers IP20 protection, categorized as NEMA Type 1, suitable for indoor installation where moderate environmental exposure is expected.
The drive's operational methodology employs Sine-Coded PWM, allowing for adjustable carrier frequency settings from 2 kHz to as high as 10 kHz. Such flexibility supports a diverse output frequency range of 0–400 Hz, catering to a wide array of motor control scenarios and enhancing system responsiveness.
Communication capabilities are augmented through a DPI Ethernet interface, which aids in seamless integration within networked systems. While the Human Interface Module is not included—indicated by a blank cover—the operational features remain robust.
An integrated Brake IGBT is present for improved braking functionality; however, it should be noted that an external resistor to complete the braking system is not part of the package. To ensure compliance with electromagnetic compatibility standards, both a CE filter and common-mode choke are integrated into the design.
A critical safety feature of the drive is the Safe-Off function, designed to enable safe operation through a secondary encoder input. The 20DD248A0EYNAEASE drive is equipped with Phase II control, reinforcing its applicability in advanced industrial automation setups.
