20DD3P4A3EYNA1DNL

The Allen-Bradley 20DD3P4A3EYNA1DNL adjustable frequency AC drive stands out with its capacity to operate at 480 volts AC. This unit is well-suited for applications that require reliable performance across three voltage phases. Capable of handling a normal-duty current of 3.4 amps, it is engineered for effective motor control in various industrial setups. An important attribute of this drive is its human-machine interface, which consists of a full numeric LCD that enables users to oversee and adjust operation settings with ease.

The compact design is secured within an enclosure rated IP20 per NEMA Type 1 standards, making it suitable for indoor environments without heavy exposure to contaminants. The drive does not feature a mechanical brake; instead, it incorporates IGBT technology for effective motor dynamics control.

The 20DD3P4A3EYNA1DNL model comes with safety features that include an adjustable bus undervoltage trip to safeguard against voltage drops and a heat sink thermistor that is monitored by a microprocessor to prevent overheating conditions. Furthermore, the logic control ride-thru allows for a duration of 0.25 seconds when the drive is in idle mode, ensuring consistent operation during brief power interruptions. In conditions of full load, the drive can sustain power for as long as 15 milliseconds, enhancing its reliability in critical applications that demand uninterrupted performance.
