UL Certified Copper 480v Transformer To 380v Transformer

Description:

Three-phase transformer generally refers to the transformer’s primary and secondary windings are electrically completely isolated, which can effectively remove the third harmonic and suppress various interferences;
Due to the discord connection of the secondary to the ground, there is no potential difference between any line of the secondary and the ground, which reduces all kinds of clutter and interference. For AC 50/60Hz,
Various three-phase power supply occasions with input and output voltages not exceeding AC1000V. It has the characteristics of wide range of applicable loads, can withstand instantaneous overload, can work continuously for a long time, is safe and reliable, saves energy and is convenient for maintenance. The input and output voltage of the product (three-phase or multi-channel input and output, etc.), the connection method,
Adjust the tap position, winding capacity distribution, secondary winding equipment, can be designed and manufactured according to the user’s requirements.

Different models could be supplied:

JBK-5KVA
JBK-10KVA
JBK-15KVA
