The 20DC105A0NNNACNNN by Allen-Bradley is a robust adjustable frequency AC drive, specifically designed to handle three-phase systems with operational requirements of 400 volts AC. This unit addresses applications with significant current demands, providing a current capability of 105 amps (normal duty). Constructed with an IP20-rated enclosure adhering to NEMA Type 1 standards, this drive is suited for installations requiring basic dust and moisture protection.
Unlike many other drives, this model features a blank cover for its human-machine interface option, indicating it may require external controls for operation. Documentation is not provided with the unit.
Key operational features include an adjustable bus undervoltage trip, enabling configurations tailored to specific working environments. The device comes with a heat sink thermistor that the microprocessor continuously monitors, ensuring that any potential overheating is detected early through an overtemperature trip function. Additionally, in configurations where the drive is inactive, logic control allows for a 0.25-second ride-thru capability. During fluctuating load conditions, the drive maintains power ride-thru for up to 15 milliseconds, enhancing overall reliability and operational efficiency.
