Product Description
The Allen-Bradley 20DJ385N0NNNBCASE is a powerful and reliable 650V DC adjustable frequency AC drive, delivering up to 385 amps for demanding industrial applications. Its open-style (IP00) design allows easy installation, while built-in protections like adjustable undervoltage trip and microprocessor-controlled heat sink thermistor ensure safe operation. Though lacking a human-machine interface and documentation, it offers logic control ride-thru and power ride-thru capabilities for enhanced uptime during brief power interruptions.
Is Your Device Showing These Signs?
The Allen Bradley 20DJ385N0NNNBCASE commonly experiences issues such as IGBT failures, capacitor degradation within the power supply, and encoder feedback malfunctions. Over time, the electrolytic capacitors in the DC bus and control power supply dry out, leading to drive faults and operational instability. The insulated gate bipolar transistors (IGBTs) are susceptible to thermal stress and electrical overstress, causing short circuits and drive trips. Encoder problems manifest as positioning errors or speed fluctuations, often due to wiring issues or encoder component failure. Resolving these problems involves replacing faulty IGBTs, recapping the power supply, and repairing or replacing the encoder and its associated wiring.
