The Schneider Electric ATV320U55N4B variable speed drive delivers efficient motor control for industrial applications. It is capable of handling an input voltage range from 380 to 500V AC, with a tolerance of ±15%, making it versatile for different power situations. Designed for heavy-duty use, this drive supports a motor power rating of 5.5 kW and has a nominal output current of 14.3 A.
The drive features a compact book-style design intended for wall mounting, allowing for space-efficient installation. With an IP20 enclosure, it offers protection against larger solid objects, enhancing its reliability in operational contexts. Additionally, it includes an integrated Class C2 electromagnetic compatibility (EMC) filter that effectively reduces electrical noise during operation.
For connectivity, the ATV320U55N4B is equipped with seven programmable digital inputs, which include support for pulse inputs, along with three open collector digital outputs. The drive also features three analog inputs that accommodate both voltage and current signals, as well as one configurable analog output for either voltage or current. This range of input and output options facilitates a variety of control and monitoring configurations.
Another significant feature is the built-in dynamic braking chopper, providing effective braking capabilities without requiring additional equipment. The switching frequency can be adjusted between 2 kHz and 16 kHz, allowing for optimization based on application needs. With an operating temperature range from -10°C to 50°C, the ATV320U55N4B ensures consistent performance in various environmental conditions. The compact dimensions of this unit are 308 mm in height, 150 mm in width, and 232 mm in depth (12.1” x 5.9” x 9.1”), making it a practical choice for space-constrained installations.
