Product Introduction
Using an isolation transformer to establish a new neutral grounding can eliminate the problems of power grid mode interference and other neutral lines. The isolation transformer converts the three-wire △ wiring into a four-wire system, and adding shielding can further It eliminates high-frequency pulse interference and noise coupled inside the transformer. Although the shielded isolation transformer can effectively prevent all kinds of interference (pulse and high-frequency noise), the transformer must be correctly and properly grounded and very strict, otherwise it will resist common noise. Mode interference will have no effect. Our company designs and produces high-quality isolation transformers for customers.

Application
Installed at the input or output end of the regulated power supply
Any system that requires isolation and shielding
Isolation transformer installed at the regulated power supply Typical applications
1. Connect an isolation transformer (delta/star) to the power input end
If the third harmonics of the power grid and interference signals are serious, use a △/isolation transformer to remove the third harmonics and reduce interfering signals.
△/isolation transformer can be used to generate a new neutral line, so that the equipment has nothing to do with the neutral line of the power grid, and avoids abnormal operation of the equipment due to poor neutral line of the power grid.
, current waveform distortion (such as third harmonic) caused by nonlinear loads can be isolated without polluting the power grid.
2. Connect an isolation transformer (star/delta) to the output end of the power supply to prevent current distortion of non-linear loads from affecting the normal operation of the regulated power supply and returning to the power grid to purify The role of the power grid.
The distortion of nonlinear load current affects the accuracy of sampling. You can sample at the input end of /△ isolation transformer to obtain a control signal that can reflect the actual situation, so that the regulated power supply can be controlled normally.
If the load is unbalanced, using /△ will not affect the normal operation of the regulated power supply.
