20DJ248A3EYNANCNL

The model 20DJ248A3EYNANCNL from Allen-Bradley is an adjustable frequency AC drive designed for robust industrial applications. This unit operates efficiently at 600 volts AC within a three-phase power system. It can manage an input current of up to 248 amps, ensuring it meets high-performance requirements. This drive is provided in an IP20-rated enclosure that complies with NEMA Type 1 standards, making it suitable for indoor installation where protection from dust and light contact is necessary.

User interaction with the drive is facilitated through a full numeric LCD screen, allowing for straightforward adjustments and monitoring. A quick start guide is included to assist in initial setup and configuration.

To enhance safety, the drive features an adjustable bus undervoltage trip, which can be tailored to specific operational needs. The braking mechanism employs IGBT technology, contributing to efficient control under various load conditions. Additionally, the system incorporates a heat sink thermistor monitored by a microprocessor that provides overtemperature protection, safeguarding the unit from potential thermal overloads.

The logic control functions allow for a ride-thru time of 0.25 seconds when the drive is not active, ensuring stability during brief non-operational periods. Moreover, the power ride-thru capability maintains operation for up to 15 milliseconds at full load, allowing the unit to withstand short power interruptions without compromising functionality. The Allen-Bradley 20DJ248A3EYNANCNL is thus engineered for reliability and efficiency in demanding industrial environments.
