As a professional electric company, we could provide customers with different kinds of AC automatic voltage regulators (AVR) and transformers.
Automatic Voltage Regulator
It is a power unit designed to automatically adjust the output voltage. Technically speaking, it can stabilize supply voltage with big fluctuation or other problems that make the power supply not applicable for electrical equipment within the predetermined voltage range, thereby the connected circuits and electrical appliances could work normally at rated voltage.
AVR contains large power type and small power type. The large power type has a power of tens of kilowatts to hundreds of kilowatts, and it is suitable for large experimental equipment. The small power type, with a power range of several watts to several kilowatts, is mainly used to supply high quality power for small laboratories or household appliances.
How to choose a proper AVR?
Some customers may find it is not easy to select an AVR that best fits their needs, here is some advice to help you out.
For an AVR, the active power (KW) that it actually outputs equals to the product of its capacity (KVA) and power factor (cosφ). Thus, the power factor, load type, rated power of target equipment and other factors must be taken into consideration during selection. Moreover, proper margin should be prepared for the output power, and it is relatively higher if the connected equipment is impact load type.
Our step-up and down transformers could convert different voltages in power grid into universal voltage, thus offering reliable power supply for electrical appliances.
