ATV320U30N4B

The ATV320U30N4B variable frequency drive, part of Schneider Electric's ATV320 series, is focused on effective motor speed control. It accepts an input voltage range of 380–500 V AC within a 3-phase configuration, with a tolerance of ±15% to +10%. Designed for heavy-duty applications, it supports a maximum continuous output current of 7.1 A. Operating at 3.0 kW, this drive caters to high-load demands.

For reducing electromagnetic interference, an integrated EMC filter complies with Class C2 standards. Additionally, the enclosure offers an IP20 protection level, ensuring safety from solid objects but not from liquid ingress.

The ATV320U30N4B supports various communication interfaces, including Modbus Serial and CANopen. It can also be expanded with optional protocol modules to enhance communication capabilities. Users benefit from seven configurable digital input channels running at 24 V DC, along with three open-collector digital output channels. The drive features three analog input ports for voltage, differential voltage, or current. Additionally, it provides a configurable analog output channel that can operate at 0–20 mA or 0–10 V DC.

With an adjustable carrier frequency range between 2–16 kHz, derating is necessary above 4 kHz to manage thermal requirements. Safety features such as Safe Torque Off (STO) and Safe Stop 1 (SS1) facilitate compliance with functional safety regulations.

Physical dimensions for this model are compact, measuring 60 mm in width, 325 mm in height, and 245 mm in depth, designed for cabinet mounting. It operates effectively in ambient temperatures ranging from -10°C to +50°C, although derating is advised for temperatures exceeding 50°C.
