2. Product Advantages
① Strong load-bearing capability: because the rated capacity of the
product is 250KVA, it has a strong load bearing capability.
② High voltage stabilization precision: the accuracy is ±2%.
③ Low risk of machine malfunction (sound performance): the voltage
regulator could work continously without malfunction for a very
long time.
④ Two working modes: manual and auto modes is alternative.
⑤ Long lifetime: it could serve for about 20 years under proper
maintenance.
⑥ Fast response rate: it reacts to voltage fluctuation quickly.
⑦ Good-quality components: all the components are made of high
quality material.
⑧ Large capacity: 250KVA is relatively large.
⑨ Wide input voltage range: the normal range is ±20% of 380V. If
it's needed, the range could be wider.
⑩ Customization available: if you have any special requirements,
please let us know. The product could be tailored to your demands.
