20DD034A3NYNANNNA

The 20DD034A3NYNANNNA from Allen-Bradley is part of the PowerFlex 700S series, classified as an adjustable frequency AC drive. This unit operates on a three-phase system with a voltage rating of 480 volts AC. It can manage input currents reaching up to 34 amps, making it effective for various industrial tasks. The drive is housed in an IP20-rated enclosure that complies with NEMA Type 1 standards.

For operator interaction, a full numeric LCD provides essential information during operation, though it should be noted that this model does not include any accompanying documentation. For efficient motor control, an IGBT braking system is utilized, contributing to precise operation. The adjustable bus undervoltage trip feature enhances safety by preventing operation under low voltage conditions.

Thermal management is facilitated by a heat sink thermistor, which is monitored by a microprocessor to avert overheating scenarios. The 20DD034A3NYNANNNA also supports a logic control ride-thru capability, allowing for a brief maintenance of operational parameters for up to 0.25 seconds when idle, ensuring settings are preserved. In instances of brief power interruptions, the unit maintains functionality for 15 milliseconds at full load conditions, thus contributing to operational resilience in challenging environments.
