AMADA Japanese Machine Tool Voltage Conversion and Stabilization Project

Aug 11, 2026

This case study describes how Winzele designed and manufactured a 50KVA integrated voltage conversion and stabilization power system for an imported AMADA Japanese machine tool. Imported machine tools are typically designed to the electrical standards of their country of origin: Japanese machine tools commonly use a three-phase 200V supply, while factory power in Europe, the United States and China is often three-phase 380V / 400V. When the voltage configuration does not directly match, it becomes an important engineering issue in imported equipment installation. This case study focuses on imported machine tool power compatibility: voltage conversion + voltage stabilization + equipment power matching.

2. AMADA Machine Tools and Global Manufacturing Applications

AMADA is a globally recognized Japanese manufacturer of metalworking equipment with a worldwide installed base in manufacturing facilities.

AMADA machine tools are widely used in industrial production environments where reliable machine operation and proper power compatibility are important considerations.

3. Imported Machine Tool Voltage Compatibility Challenge

Different countries use different industrial power standards.

Japanese machine tools commonly require specific voltage configurations, including three-phase 200V systems. When Japanese equipment is installed at an overseas facility outside Japan, the local industrial power supply may not directly match the machine’s power requirements.

Typical challenges in this case:

Factory power: Three-phase 380V / 400V
Machine requirement: Three-phase 200V
Engineering requirement: Voltage conversion and stabilization

Imported machine tools often require customized power solutions because their original electrical specifications may differ from local industrial power standards. Winzele provides customized power matching solutions for imported machine tools, including voltage stabilization and voltage conversion.

4. Integrated Voltage Conversion and Stabilization Solution

Winzele supplied an integrated voltage conversion and stabilization system for this project, combining a voltage stabilizer and a step-down transformer: the input voltage is stabilized first, then a step-down transformer matches the AMADA machine’s three-phase 200V requirement.
