Core functional selling points (differentiated core)
With load voltage regulation, the output voltage can be adjusted without cutting off the load or power outage, solving of "power outage during voltage regulation" for ordinary transformers and ensuring continuous power supply
The voltage is precise and stable, and the voltage regulation accuracy can reach ± 0.5%~± 1% for complex working conditions. It can compensate for real-time voltage fluctuations in the power grid or adapt to voltage offsets caused by load changes, improving product qualification rate and equipment operation stability.
Wide range voltage regulation, suitable for multiple scenarios. The voltage regulation range usually covers ± 10% of the rated voltage (customizable), which can adapt to voltage differences in different regions of the power grid. One device can adapt to multiple working conditions, reducing customer selection and replacement costs.
Mainly made of high-quality steel, manufactured through welding or acid pickling phosphating processes
Oxygen free copper rod with a purity of over 99.95% copper content
