2. Transformer Features

① Strong load-bearing capability: this three phase dry type isolation transformer, with 400KVA capacity, has a strong load-bearing capability.

② Anti-interference: because the primary winding and the secondary winding is separated from each other, the transformer has the feature of anti-interference.

③ High output accuracy: the output voltage could be ±2% of rated capacity.

④ Clear display of input and output data: the input voltage, output voltage, and output current are shown respectively in three pointer meters so that you could know the real-time situation of the voltage.

⑤ Copper windings: three windings are all made of copper wire, which strengthens the electricity conductivity and prolongs the service life of the transformer.

⑥ Fast reaction speed: the transformer reacts quickly in changing voltage.

3. Main Advantages

4. Usage and Maintenance

① Check the main body and spare parts of the transformer regularly to ensure its normal and sound work.
② Do not over-load in case the transformer would be damaged.
③ Turn off the power if you do not use the transformer for your safety.
④ Install it in a well-ventilated place to facilitates better heat dissipation when it works.
⑤ Do not use it in a situation of heavy vibration.
