ISOLATION TRANSFORMER, 3 PHASE STEP UP TRANSFORMER,
3 PHASE STEP DOWN TRANSFORMER

An Ultra Isolation Transformer is a three-phase transformer used to transfer electrical power from an AC power source to equipment or devices while electrically isolating the load from the supply. The input supply can be single-phase or three-phase, and the isolation is primarily provided for safety and equipment protection.

These three-phase step-up or step-down isolation transformers provide galvanic isolation and are widely used to protect against electric shock, suppress electrical noise in sensitive equipment, and transfer power between two circuits that must remain electrically separated. In the industry, they are also commonly referred to as three-phase step-down transformers.

Properly designed three-phase step-up and step-down isolation transformers effectively block interference caused by ground loops. Three-phase transformers equipped with electrostatic shielding are especially suitable for powering sensitive equipment such as computers, laboratory instruments, and precision machinery.

Common Three-Phase Step-Up Transformer Models

  • 240 V AC to 480 V AC, Three-Phase Step-Up Transformer

  • 220 V AC to 440 V AC, Three-Phase Step-Up Transformer

  • 200 V AC to 415 V AC, Three-Phase Step-Up Transformer

Purevolt has a team of experienced professionals who work diligently and to the best of their abilities to meet and exceed customer requirements.

We continuously test and evaluate our three-phase transformers across multiple quality and technical parameters to identify opportunities for improvement. Our three-phase step-down transformers are widely accepted in the market for their reliability, durability, and consistent performance.

Simply put, three-phase step-down transformers are used to reduce voltage from one level to a lower, desired level (for example, 415 V to 240 V). Similarly, three-phase step-up transformers are used to increase voltage from a lower level to a higher level (for example, 240 V to 415 V).

These transformers can be designed in various configurations such as Delta–Star, Star–Star, and Star–Delta, depending on application requirements. They are commonly used with imported machinery from Western countries such as the USA and Asian countries such as Japan.

Three-phase step-down transformers and single-phase or three-phase dry-type low-voltage (LV) isolation transformers are manufactured as step-up or step-down units to adjust voltage levels within the LV power distribution network.

Three-phase isolation transformers can be supplied as either open-type three-phase transformers or enclosed-type isolation transformers. Enclosed transformers are custom-designed to suit harsh and demanding operating conditions.

Indoor units with IP21 or IP42 protection are manufactured using mild steel enclosures with industrial-grade powder coating. Outdoor three-phase step-down transformers are provided with IP56 ingress protection, featuring robust, powder-coated enclosures for enhanced durability.

With over 25 years of experience in three-phase transformer design and manufacturing, Purevolt has successfully exported three-phase isolation transformers to numerous countries worldwide. These three-phase step-up and step-down transformers are widely used with online UPS systems, sine wave UPS systems, industrial machinery, and various electrical equipment.
