How to choose the right transformer voltage level according to demand?

Selection of commercial voltage transformers according to equipment requirements

Specify the rated transformer voltage of the equipment

Each piece of equipment has its rated standard american voltage. Which is usually labeled on the equipment nameplate or in the instruction manual.

Example:

  • Industrial motors: commonly rated at 380V or 480V.Transformers electricity helps deliver the right industrial voltage in usa to homes and businesses.
  • Data centre servers: mostly 208V or 400V.The output voltage of the voltage of transformer electricity must match the rated voltage of the equipment to avoid damage to the equipment due to over or under voltage.

Consider the power requirements of the device

  • High power equipment: such as production lines and industrial robots, usually need higher voltage (e.g. 480V, 600V) to reduce current loss and improve transmission efficiency, it is recommended to choose.
  • Low-power devices: such as control systems and small industrial equipment, usually use lower voltage (e.g. 240V, 208V), simple adaptation and high security. The transformer electrical system converts high voltage to a lower voltage for safe use in homes.

Determine the operating environment of the equipment

  • High safety requirements: e.g. medical equipment, data centres, it is recommended to choose low voltage transformers (e.g. 208V) to ensure safety. The transformer electric device reduces high voltage for safe use. The United States power voltage is 120V for homes and 240V for larger appliances.
  • High-reliability requirements: e.g. new energy equipment and specific transformers need to be selected according to the input voltage of the inverter or battery (e.g. 800V for photovoltaic). The transformer’s electrical systems help adjust voltage levels for different uses.

Multi-device compatible voltage selection

There may be equipment with multiple voltage requirements on a production line. In this case, you can choose a multi-output building transformer to provide multiple voltages and reduce the risk of equipment incompatibility. Example:

  • Industrial scenarios where both 380V and 220V equipment are powered.
  • Data centre with both 208V servers and 480V air conditioners.

Voltage regulation for special applications

If the rated voltage of the equipment does not match the local grid standard (e.g. 400V equipment in Europe running on 380V grid in China). The voltage can be adapted through a transformer to ensure that the equipment operates normally.
