Allen-Bradley designs the 20DD156A3EYNANDNL drive as part of the PowerFlex 700S series. This adjustable-frequency AC drive operates at a three-phase voltage level of 480 volts and is rated for a maximum current of 156 amps, making it ideal for demanding applications.

This unit is encased in an IP20-rated enclosure that meets NEMA Type 1 specifications, providing protection suitable for indoor settings. A full numeric LCD acts as the human-machine interface, enabling users to monitor and operate the drive easily.

Safety features are prominently integrated into the design of the 20DD156A3EYNANDNL. It employs an IGBT braking system to ensure reliable and efficient performance. Furthermore, the adjustable bus undervoltage trip gives users the flexibility to set voltage thresholds according to operational requirements.

An onboard microprocessor monitors a heat sink thermistor to mitigate overheating. This control allows for a logic ride-thru time of 0.25 seconds, preserving operational stability during brief power interruptions. Additionally, the device can sustain power for up to 15 milliseconds when fully loaded, ensuring consistent performance under varying electrical conditions.
