January 14, 2010 – Lenze-AC Tech released I/O modules for SMVector NEMA 1 and NEMA 4X Inverters. Available in two configurations, ESVZAL0, and ESVZAL1, the modules supplement the standard I/O functions by providing one programmable form C relay output (ESVZAL0) or one programmable form C relay output and 2 programmable digital inputs (ESVZAL1).The I/O modules do not add to the overall size of the SMVector inverter as they fit right into the SMVector inverter terminal cover, allowing for easy field installation. The SMVector inverter drive provides four modes of operation – V/Hz, Enhanced V/Hz, Vector Speed, and Torque – plus high starting torque, auto-tuning, advanced low-speed control and dynamic speed regulation. SMVector has an input voltage ranging from 120VAC 1-phase to 600 VAC, 3-phase.
