The 20DD3P4A3EYYANNNN model is an adjustable frequency AC drive from Allen-Bradley, falling under the Rockwell Automation brand. This unit operates effectively at an input voltage of 480V AC across three phases, managing a maximum normal-duty current of 3.4 amps. The drive's design incorporates an IP20 enclosure that complies with NEMA Type 1 standards, ensuring adequate protection for indoor applications.
A full numeric LCD provides users with essential feedback and facilitates straightforward interaction with the device. The drive features several safety and control options. An IGBT braking system is included for efficient motor control, and there is an adjustable bus undervoltage trip to safeguard the system against low voltage conditions.
Thermal management is enhanced by a heat sink thermistor, which operates under the supervision of a microprocessor to detect overheating and trigger an overtemp trip if necessary. When the drive is inactive, logic control allows for a ride-thru period of 0.25 seconds, promoting stability during brief power losses. Under conditions of full load, the power ride-thru function supports operation for up to 15 milliseconds, ensuring continued performance during transient voltage drops.
