The mini voltage transformer is used to convert high voltage input AC into low voltage output by a certain ratio. With the help our product, a voltage testing device with small measuring range will be able to test on high voltage. It can also serve as a protective device to protect important elements in the circuit when the electric power system fails.

The mini voltage transformer can convert 50Hz or 60Hz AC. It has high accuracy and consistency. The accuracy is ensured by XF20-6B AC/DC instrumentation calibrator, high voltage resistance property ensured by YD2665 voltage resistance tester, and inductance tested by YD2816A wide frequency LCR digital bridge.

Its epoxy resin wrap cover packaging not only is ideal for PCB mounting, but also provides high insulation strength. This RoHS certificated product has dielectric strength of 3kV/1mA. The working temperature ranges from -25℃ to 55℃, relative humidity is less than 90%, and atmospheric pressure ranges from 860mbar to 1,060mbar.

We provide several models to acquire different voltage conversion ratio by different turns ratio to meet your practical needs. Easy to be connected into circuit, it is a very utility voltage conversion device.

We are a specialized mini voltage transformer manufacturer in China. We provide various types of products such as wire lead current transformer, split core current transformer, industrial heat sink and lead wire power transformer.
