Lenze ESV373N04TXB SMVector Variable Frequency Drive

The Lenze ESV373N04TXB (ESV373N04TXB) is an industrial variable frequency drive engineered for dynamic AC motor speed and torque regulation within the SMVector drive family. Designed to operate on three-phase 400V to 480V AC supply lines, this inverter delivers reliable motor control across automated manufacturing, material handling, processing machinery, and pump or fan installations. The drive provides robust performance for three-phase asynchronous motors, integrating advanced vector control algorithms alongside standard V/Hz operation to maintain precise velocity regulation and high starting torque under demanding duty cycles. Built into a compact industrial enclosure with an integrated heatsink for efficient thermal dissipation, the unit weighs approximately 10 kg and supports panel mounting inside control cabinets. Flexible control terminals accommodate analog and digital inputs and outputs for seamless interfacing with supervisory programmable logic controllers, sensors, and remote operator interfaces. Engineered for continuous duty in harsh industrial environments, the Lenze ESV373N04TXB ensures stable velocity management, energy efficiency, and reliable overload protection across diverse industrial automation machinery.
