Power transformer with distribution board (double-shielded type with built-in noise filter)

Power transformer with distribution board (double-shielded type with built-in noise filter)

This is a patented product developed by our company, a power transformer that supplies clean power without noise to precision equipment. *Made to order.

We offer power transformers with distribution boards (transformer panels/double-shielded noise filters built-in). This is a patented product developed by our company, designed to supply clean power without noise to precision equipment, including computers. Additionally, compared to other products, it has less voltage drop due to increased load current, and there is no leakage current from capacitors, eliminating any concerns about electric shock risks or false alarms from leakage detection. As this is a made-to-order product, we can propose specifications tailored to your site requirements. Since it is possible to establish an output circuit, the functions of the distribution board and transformer panel can be consolidated into one panel, allowing for reduced installation area and cost savings. 【Four Types】 ■ Portable Type ■ Rack Mount Type ■ Standard Type ■ Deluxe Type *For more details, please download the PDF or feel free to contact us.
