20KVA isolation transformer 3 phase step down

20KVA isolation transformer 3 phase step down

20KVA isolation transformer designed to step down or step up 3-phase voltage to usable range.

For example step down 480V to 208V. Dry-type transformers are affordable, can be used in any equipment, and are very safe.

The primary and secondary windings of the isolation transformer are separated by an aluminum/copper shielding layer, and are widely used in various power supply places with a frequency of 50Hz/60Hz.

High quality and safe isolation transformer 20KVA isolation transformer is manufactured and supplied by Shuogong Power, a leading transformer company in China.

The rated power is 20KVA and it is suitable for 3 phase electricity. If you need to use it for single phase electricity, we also have corresponding product models.

20KVA three phase isolation transformer is a three phase dry type transformer, its function is to step down, and the primary and secondary windings are insulated separately.

Tips: Benefits of using isolation transformers

1. Reduces Surges

A power surge happens when the input voltage in devices exceeds the required level. A surge can damage all appliances and electronics plugged into power.

An isolation transformer minimizes power surges. It insulates DC signals from the power source to allow equipment to function without interruptions, therefore reducing the chance of property damage from power surges.

2. Enhances Safety

Assured safety is the most notable benefit of isolation transformers. At times, touching electrical devices can lead to dangerous electric shocks. An isolation transformer completes the power source’s circuit, protecting you from electric shocks.

3. Increases Power Quality

An isolation transformer improves the quality of power on equipment. The transformer uses a Faraday shield to reduce potential current leakage. Electrical devices in the home or business use all current coming from the power source. With an isolation transformer, importance equipment can achieve optimal performance.

4. Reduces Noise

Electrical noise impacts the performance of a machine by interfering with the signals. It comes from unwanted electrical signals that enter into power and signal circuits.

An isolation transformer reduces electrical noise in electrical devices. The Faraday shield in the transformer prevents electric fields from interfering with power flow. Thus, unwanted currents cannot interrupt power and signal circuits in equipment.
