The part number 20DD300A0NNNNNASE is a component in the PowerFlex 700S series manufactured by Allen-Bradley. This adjustable frequency AC drive is specifically designed to function at a voltage of 480V AC. It is configured for three-phase operation and can handle input currents of up to 300 amps. The drive has a compact IP20 enclosure that meets NEMA Type 1 specifications, ensuring protection from dust and solid objects. A key aspect of this model is the blank cover used for its human-machine interface, simplifying its design while eliminating unnecessary controls.
While it does not come with a braking feature, the drive is equipped with an adjustable bus undervoltage trip. This function enables customization based on application requirements. In terms of thermal management, the drive is designed with a heat sink thermistor. This component is monitored by a microprocessor, enhancing safety by detecting and responding to overheating conditions.
For system stability, the 20DD300A0NNNNNASE supports logic control ride-thru capability of 0.25 seconds when the drive is not in active operation. In full-load scenarios, the power ride-thru feature can manage brief power disturbances for up to 15 milliseconds. This product is suitable for a range of industrial applications requiring reliable motor control and efficient power management.
