Variable Auto Transformer Suppliers

A Variable Auto Transformer (VAT) is a type of transformer that can vary the output voltage by adjusting the position of a movable contact on a winding. It is also known as a Variac or an Autotransformer. VATs are commonly used in laboratory experiments, testing equipment, and in the control of electrical devices. They are also used in audio equipment to adjust the voltage of the power supply to control the volume of the sound. VATs are simple, reliable, and cost-effective devices that can provide a stable output voltage over a wide range of loads.

A Variable Auto Transformer, also known as a Variac, is a type of transformer that allows for the adjustment of the output voltage. The benefits of using a Variable Auto Transformer include:

• Voltage Regulation: A Variac allows for the adjustment of the output voltage, which can be useful in situations where a precise voltage is required.
• Cost-Effective: A Variac is a cost-effective solution for voltage regulation compared to other methods such as using a transformer with multiple taps.
• Easy to Use: A Variac is easy to use and can be adjusted by simply turning a knob.
• Protection: A Variac can provide protection against voltage surges and spikes, which can damage electronic equipment.
• Energy Efficiency: A Variac can help reduce energy consumption by allowing for the adjustment of voltage to match the requirements of the equipment being used.

Versatility: A Variac can be used in a variety of applications, including testing and calibration, laboratory experiments, and industrial processes.

The maximum voltage and current rating of a Variable Auto Transformer can vary depending on the specific model and manufacturer. It is important to consult the product specifications or contact the manufacturer for this information.

However, in general, the input voltage range of a Variable Auto Transformer can vary depending on the model and manufacturer. It is important to check the specifications of the specific model to determine its input voltage range.

However, the output voltage range of a Variable Auto Transformer typically depends on the model and specifications of the device. It can range from a few volts to several hundred volts. It is important to refer to the manufacturer's specifications for accurate information on the output voltage range of a specific Variable Auto Transformer.

However, the accuracy of the output voltage of a Variable Auto Transformer depends on the quality and precision of its components and design. Generally, high-quality Variable Auto Transformers can provide accurate output voltage within a range of ±1% to ±5%.

There is no information provided about the warranty period for the Variable Auto Transformer.

However, in general, some safety features that may be included in Variable Auto Transformers are:

• Overload protection: This feature automatically shuts off the transformer if the load exceeds the rated capacity, preventing damage to the transformer and the connected equipment.
• Short-circuit protection: This feature protects the transformer from damage caused by a short circuit in the load.
• Ground fault protection: This feature shuts off the transformer if a ground fault is detected, preventing electrical shock to the user.
• Overvoltage protection: This feature protects the connected equipment from damage caused by voltage spikes or surges.
• Thermal protection: This feature shuts off the transformer if it overheats, preventing damage to the transformer and the connected equipment.

Enclosure protection: The transformer may be housed in an enclosure that provides protection against accidental contact with live parts and prevents dust and moisture from entering the transformer.

However, the price range of a variable auto transformer can vary depending on the brand, model, and specifications. Generally, they can range from $50 to $500 or more.
