A 480-208Y/120 volt 3 phase transformer is widely used when a facility has a 480V three-phase power source but needs a lower-voltage 208Y/120V three-phase, four-wire system for equipment, lighting, receptacles, controls and other electrical loads. Among the available sizes, 75 kVA 480-208Y/120 volt 3 phase transformers are a particularly useful configuration for commercial and industrial […]
A rectifier transformer is a special-purpose transformer designed to supply power to a rectifier system that converts AC electrical power into DC power. Unlike a conventional power or distribution transformer, a rectifier transformer is designed around the requirements of the downstream rectifier, including DC voltage, DC current, pulse number, harmonic performance, phase shifting and load […]
Transformers are essential electrical devices used to transfer AC electrical energy from one circuit to another while changing voltage and current levels. They are widely used in power generation, transmission, distribution, industrial equipment, commercial buildings, automation systems and electrical machinery. There are many different types of transformers, and they can be classified according to their […]
Automatic Voltage Regulator (AVR) and voltage stabilizer are two commonly used terms for equipment that corrects fluctuations in AC power and provides a more stable voltage to electrical loads. If you are searching for an industrial AVR, AC voltage stabilizer, servo voltage regulator, or automatic voltage stabilizer, you may notice that manufacturers often use these […]
接地變壓器，亦稱為接地變壓器或中性點接地變壓器，是一種專用變壓器，用於建立中性點，並在三相電力系統中為零序電流及接地故障電流提供受控的流路。在沒有自然中性點的未接地系統或三角接系統中，其作用尤為重要。 透過 […]
An autotransformer is a transformer that uses a single continuous winding with one or more taps to change AC voltage. Unlike a conventional two-winding transformer, part of the winding is shared by the input and output circuits. This design makes an autotransformer smaller, lighter and highly efficient for certain voltage conversion applications. However, it does […]
Low voltage transformers reduce a higher AC voltage to a lower voltage required by electrical equipment, control systems, lighting, machinery, and other loads. They are widely used in residential, commercial, and industrial electrical systems. Depending on the application, a low voltage transformer may provide common secondary voltages such as 12V, 24V, 48V, 110V, 120V, 208V, […]
A voltage stabilizer for generator is an external power regulation device used to maintain stable AC voltage between a generator and connected electrical equipment. It can be used with diesel generators, gasoline generators, portable generators and standby generators when additional voltage regulation is required. Most generators already have a built-in AVR (Automatic Voltage Regulator). However, […]
A whole house voltage stabilizer is designed to regulate unstable incoming electricity before it reaches the electrical circuits and appliances throughout a home. It helps correct voltage fluctuations, including low voltage and overvoltage, providing a more stable power supply for residential equipment. Unlike a basic surge protector that mainly protects against short-duration voltage spikes, an […]
