Main Series and Their Applications

Customers buy Schneider from us mostly to replace legacy ATV31/ATV61 units on equipment that is already running. Top movers over the past 12 months: ATV310HD11N4E at 11 kW (6 units), ATV320U15N4C at 1.5 kW (3), ATV320U07M2B single-phase 220 V at 0.75 kW (3), ATV610D30N4 at 30 kW (3). It is a predictable brand, no surprises. Price runs 30-50% above Chinese and Japanese drives, but on tenders it is often written directly into the spec.

11 series in the catalogue, but only three are real movers: Altivar 310 (entry, up to 11 kW. Simple. Cheap), Altivar 320 (built-in STO for machine safety), Altivar 610 (industrial up to 160 kW). One special variant: Altivar 320 Solar with MPPT for direct PV-panel input without batteries. Customers take it for farm irrigation systems. One caveat: ATV12, ATV31, and ATV61 are end-of-life. If you are repairing one, ask us. We sometimes source B-stock.

Schneider Electric Altivar VFD Series

Altivar 12 — Ultra-Compact Series

4 models, 0.18–2.2 kW. The smallest and most affordable Altivar series. For simple low-power tasks: small pumps, fans, and packaging equipment.

Altivar 310 — Basic Series for General Applications

8 models, 0.75–11 kW. Sensorless vector control, Modbus RTU. Conveyors, hoists, and low-power pumps.

Altivar 320 — Universal Series for Machine Building

22 models, 0.18–15 kW. Built-in STO safety function, CANopen, Ethernet/IP. Industry standard for machine tools, packaging, and textile machinery.

Altivar 320 Solar — Series for Solar Pumping Systems

24 models, 0.37–15 kW. Specialised drive for photovoltaic pumping systems: MPPT, dry-run protection, battery-free operation.

Altivar 340 — Series with Extended Communication Protocols

19 models, 0.75–55 kW. EtherNet/IP, Profinet IO, Modbus TCP. For automated production lines with network control.

Altivar 610 — Series for High-Power Industrial Systems

20 models, 0.75–160 kW. High overload capacity, built-in PID, Modbus/Ethernet. Compressors, pumps, and fans at medium and high power.

Altivar 212 — Pump and Fan Series

33 models, 0.75–75 kW. Optimised for Q/H pump and fan curves. Water supply, HVAC, and climate systems.

Altivar 630 / 930 / 650 / 950 — Industrial Drive Series

Altivar 630 and 930: 16 models each, 0.75–75 kW. Altivar 650 and 950: 28 models each, 0.75–75 kW. Four series for different load profiles and communication requirements. Suitable for pumps, conveyors, and compressors in medium and large enterprises.

Which Altivar Series to Choose?

Solar pumping system without batteries — Altivar 320 Solar. Machine tool or packaging machine — Altivar 320. Pump or fan up to 75 kW — Altivar 212. Production line with Profinet or EtherNet/IP — Altivar 340. High-power compressor or pump up to 160 kW — Altivar 610.

Equipment Advantages

When selecting equipment, consider overload capacity, integrated EMC filtering, and industrial protocol support.

Frequently Asked Questions

Who manufactures Schneider?

Schneider Electric SE. A French group headquartered in Rueil-Malmaison near Paris, with plants across Europe and Asia. The drives carry the Altivar name, and that name has not changed in decades. We stock 220 Altivar models, priced from UAH 11,600 with VAT. Warranty is 24 months from the date of purchase.

How does a frequency inverter work?

In three stages. The 50 Hz mains is first rectified into DC, a capacitor link smooths it, and the output IGBTs assemble three-phase AC at the frequency you asked for using PWM. Change the frequency and motor speed changes with it, while the drive trims the voltage itself so the flux does not drift. Altivar 320 does this with sensorless vector control. Altivar 630 and 930 add encoder feedback and the full set of industrial protocols.

Which frequency inverter converts 380 to 220 V?

There is no direct 220 to 380 conversion. A single-phase Altivar with a 220 V input puts out 3×220 V, and that is physics rather than a firmware limit. We have 18 such models in stock, Altivar 12 at 0.75-2.2 kW and the M2-coded Altivar 320 at 0.37-2.2 kW. A 380 V three-phase motor runs from them once the links are moved to delta, provided the nameplate shows 380/220 V. Above 4 kW motors are usually wound for 380/660 V, and then you need three phases.

What is a frequency inverter?

A drive that controls induction-motor speed by varying supply frequency and voltage. Instead of switching on at 50 Hz and living with it, you get any speed within the working range, plus ramp-up and ramp-down over a set time. At Schneider this is the Altivar range, from the ultra-compact ATV12 at 0.75 kW to Altivar 610 at 160 kW. Eleven series are in stock.

What is a frequency inverter needed for?

So that a motor runs at the speed the process needs. On pumps and fans that cuts consumption directly; on machine tools and packaging lines it gives accurate speed plus a smooth ramp that spares belts, chains and bearings from a slammed start. On complex machines you add feedback and drive synchronisation. Most of our buyers take Altivar 320 and Altivar 340. Machine tools and packaging, mainly.

Which converter turns 1 phase into 3 phases?

Any drive with a single-phase input: it takes one 220 V phase and delivers three phases to the motor. Output voltage stays 220 V, not 380. In our stock that means single-phase Altivar 12 and Altivar 320, eighteen models up to 2.2 kW. For a 380/220 V three-phase motor you switch the windings to delta. If you need to feed a 380 V motor with no rewiring, a three-phase input is required.
