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.
