Custom-made transformers ideal for imported equipment from overseas: Data Center Edition

Custom-made transformers suitable for imported equipment from overseas are designed according to the type of equipment, usage environment, and differences in voltage and frequency. In Japan, a power supply of 100V (50Hz or 60Hz) is generally used, but overseas equipment often operates at different voltages (e.g., 110V, 220V, 240V, etc.) and frequencies (50Hz or 60Hz) depending on the country, making it unusable as is. Custom-made transformers are essential for adjusting these differences and ensuring that the equipment operates safely and efficiently.

basic information

IT equipment and servers (e.g., servers for data centers) Recommended transformer: single-phase or three-phase transformer (e.g., 208V → 100V step-down, UPS compatible) Specific example When using an American-made server rack (operating voltage: 208V, 60Hz) in Japan, a custom-designed step-down transformer (capacity: 10kVA to 30kVA) is required. Compatibility with UPS (uninterruptible power supply) is also considered. Benefits - Prevents data loss and system downtime with stable power supply. - Reduces communication errors by adding noise suppression features. - Allows for large-capacity design that can accommodate multiple devices. Data center edition (rack servers/blade servers/storage area networks/network-attached storage/UPS/cooling units (CRAC/CRAC Units)/server racks/module data centers, etc.)

**Benefits of Custom-Made Transformers** - **Flexibility** Optimal design tailored to the specifications of the equipment (voltage, frequency, power consumption). - **Efficiency** Minimizes unnecessary power loss, achieving energy savings. - **Safety** Custom features such as overcurrent protection and temperature protection can be added, reducing the risk of accidents. - **Long-term Cost Reduction** Compared to off-the-shelf general-purpose transformers, a design optimized for the equipment helps reduce maintenance costs. When inquiring about custom-made transformers, it is helpful to provide the following information for a smoother process: - Rated voltage and power consumption of the equipment (check the specifications) - Power supply specifications for the region of use (in Japan, either 100V or 200V, 50/60Hz) - Installation environment (indoor/outdoor, temperature, humidity, etc.) - Required safety standards or certifications (e.g., UL, CE, JIS, etc.) For voltage conversion when importing equipment from overseas, please consult with Nikkou Electric, a transformer manufacturer with 70 years of experience, known as "The Voltage Conversion Professionals." We design, manufacture, and sell custom transformers tailored to your equipment, starting from just one unit! We will work closely with you to address any challenges to ensure smooth operation of overseas equipment in Japan.
