Schneider Electric ATV320U22N4C Altivar 320 Variable Speed Drive 2.2kW
Overview
The Schneider Electric ATV320U22N4C is a compact Altivar Machine variable speed drive rated for 2.2kW motor loads on a 380–500V three-phase supply, positioned between the smallest and mid-power members of Schneider Electric’s Altivar 320 range for OEM machine builders. In the part-number scheme, “U22” identifies the 2.2kW power rating, “N4” the 380–500V three-phase input class, and the trailing “C” the compact enclosure with cage-clamp spring terminals fitted across the smaller ATV320 frame sizes. This power class is a frequent specification for small-to-medium pumps, extraction fans, and light conveyor sections where a step up from the entry 1.5kW model is needed without moving to a larger frame.
As the official authorized partner and exclusive regional representative for Schneider Electric, Seven Star LLC proudly supplies the Schneider Electric ATV320U22N4C variable speed drive to industrial clients throughout the Sultanate of Oman, Muscat, and the wider GCC region. Our engineers assist machine builders, EPC contractors, and plant maintenance teams with drive sizing, motor compatibility verification, and commissioning support so that every ATV320U22N4C installed carries full manufacturer warranty and genuine Schneider Electric firmware.
Operating Principle
The Schneider Electric ATV320U22N4C operates on the same pulse-width-modulation (PWM) principle as the rest of the ATV320 range: the incoming 380–500V three-phase supply is rectified to a DC bus, and an IGBT inverter stage switches that bus at up to 4 kHz to synthesize a variable-voltage, variable-frequency output. Output frequency is adjustable across 0.1 to 599 Hz, giving fine-grained control of connected motor speed and torque for both standard and higher-speed applications.
Because the motor’s speed is set electronically rather than by mechanical throttling, the ATV320U22N4C allows three-phase asynchronous and synchronous motors up to 2.2kW to ramp smoothly from zero to full speed, avoiding the inrush current and mechanical shock of direct-on-line starting. The practical benefit is reduced wear on couplings, belts, and bearings, lower peak electrical demand, and tighter process control for small-to-medium pumping, ventilation, and material-handling duties.
Engineering Design of the Schneider Electric ATV320U22N4C
The Schneider Electric ATV320U22N4C is built into Schneider’s compact ATV320 book-format enclosure, measuring approximately 140mm wide by 184mm high (227.9mm with the EMC mounting plate fitted) by 158mm deep, with a net weight of 2.1kg — sized to sit inside an OEM control panel alongside PLCs and other automation hardware without a dedicated drive cabinet. The “C” variant’s cage-clamp spring terminals allow panel builders to land power and control wiring with a screwdriver push, saving assembly time compared with torque-critical screw terminals.
An onboard RJ45 port supports Modbus and CANopen over a 2-wire RS485 connection, giving native PLC or SCADA connectivity without a separate communication module in most installations. A Class C2 EMC filter is integrated as standard, and the drive carries an IP20 rating to EN/IEC 61800-5-1, with an ambient operating range of -10°C to 50°C without derating (extending to 60°C with output current derating) suited to enclosed panel environments common on regional production floors.
Key Features
Machine builders and panel integrators specifying the Schneider Electric ATV320U22N4C in Oman get a mid-entry drive that bridges the gap between the smallest ATV320 models and higher-power frames. Core capabilities include:
- 2.2kW rated output power for three-phase asynchronous and synchronous motors on 380–500V supplies.
- Continuous output current of 5.5A at 4 kHz switching frequency for heavy-duty applications.
- Compact book-format enclosure at 2.1kg, dimensioned 140 x 184 x 158mm for panel banking.
- Cage-clamp spring terminals on the “C” variant for fast, tool-light panel wiring.
- Native RJ45 Modbus and CANopen connectivity over 2-wire RS485 built in.
- Integrated Class C2 EMC filter simplifying regulatory compliance on the machine build.
- IP20-rated enclosure to EN/IEC 61800-5-1 suited to standard control cabinets.
- Permissible temporary overload of 1.5 x nominal current for 60 seconds on demanding starts.
Industrial Applications
The balanced power and compact footprint of the Schneider Electric ATV320U22N4C suit small-to-medium pumps, extraction and cooling fans, and light conveyor sections on packaging, water treatment, and light manufacturing lines across Oman’s growing industrial base. System integrators supplying utility pump skids, HVAC fan coil units, and food-processing equipment to facilities in Muscat and across the Sultanate frequently specify the ATV320U22N4C where the entry 1.5kW model lacks sufficient current headroom.
Commercial building services contractors, hospitality-sector facilities, and light industrial plants throughout the Sohar and Salalah economic zones also rely on this Altivar Machine power class for fan, pump, and conveyor speed control. As the officially authorized partner for Schneider Electric in the region, Seven Star LLC distributes the ATV320U22N4C to system integrators and OEM panel builders who require genuine hardware, accurate lead times, and manufacturer-backed technical support for both new machine builds and drive replacement programs.
