Converting the Nidec C200 3-Phase 380V Inverter into a 3-Phase 220V Inverter

The discovery that the Nidec C200 3-phase 380V inverter can control 3-phase 220V motors and operate with 220V input voltage is an interesting finding that came from a real customer request.

In the Vietnamese market, very few inverter suppliers have 3-phase 220V inverters readily available. Most of them only stock 1-phase 220V to 3-phase 220V or 3-phase 380V models. For the Nidec C200 series, the 1-phase 220V input to 3-phase 220V output version has a maximum capacity of only 2.2kW.

The Real-World Situation

At a Japanese factory that uses 3-phase 220V power, there was a need to control 3-phase 220V motors with large capacities. However, ordering suitable inverters from Vietnam would result in high costs and long lead times.

In addition, some Vietnamese companies that import Japanese domestic machinery or production lines face similar difficulties. If they install a step-down transformer for 220V, it increases both costs and power losses. On the other hand, replacing all motors with 380V versions would also be complex and expensive.

Song Nguyên’s Solution

Fortunately, the Song Nguyên technical team discovered that the Nidec C200 inverter software includes a special function that allows users to flexibly limit both input and output voltage — a feature that is rarely found in other inverter brands Song Nguyên has worked with.

With this function, customers using 3-phase 220V power no longer need to worry about short supply, high prices, or production interruptions due to unavailable spare units. At the same time, distributors don’t need to spend extra on stocking 3-phase 220V inverters, which are typically in low demand.

Now, you simply need to contact Song Nguyên to select a standard Nidec C200 inverter and request pre-configuration for your specific application.

With its durability and reliability, the Nidec C200 inverter is the top choice for businesses seeking to improve operational efficiency. This product is steadily proving its position in the market with stable and efficient performance, helping companies reduce costs and enhance competitiveness.

Note: When using a Nidec C200 380V inverter to drive a 220V motor, you must select the inverter based on current (Amperes) rather than power (kW), because the rated current of a 380V inverter is much lower than that of a 220V inverter with the same motor power rating.

In urgent situations that require quick solutions, customers can consider using the Nidec C200 inverter solution provided by Song Nguyên.
