Schneider ATV320U30N4C, variable speed drive, ATV320, 3 kW, 380…500 V, 3 phases, compact

This Altivar 320 variable speed drive can feed 3-phase synchronous and asynchronous motors. Its compact form factor allows vertical stacking of drives inside machine frames. It works at a rated power up to 3kW / 4hp and a rated voltage from 380V to 500V AC. Its robust design with IEC 60721-3-3 class 3C3 coated printed circuit boards allows to extend machine availability in harsh environmental conditions, for example at ambient temperatures of up to 60°C without the need of additional cooling. It incorporates functions suitable for the most common applications, including torque and speed accuracy at very low speed, high dynamic performance with flux vector control without sensor and extended frequency range for high-speed motors. It also incorporates parallel connection of motors and special drives using the voltage/frequency ratio and static speed accuracy and energy saving for open-loop synchronous motors. The drive software includes 5 safety functions that help machines meet safety requirements, whether or not they are used in conjunction with a Preventa safety module.
