power Renge ：1-2000KVA

 Provides electrical isolation between the load and the power side. In the IT distribution system, electrical shock is prevented to protect the insulation of the connected equipment from damage, and neutral connections can be provided to form isolation or grounding.

 K-factor：

The electric power network and user load three harmonic voltage and other odd harmonics exist, will all produce harmonic voltage and harmonic current component in the additional isolation transformer coil, when additional harmonic component is large enough, will enable the isolation transformer overload over temperature operation, reduce the operation life of isolation transformer, even burned within a short period of time K, the coefficient of isolation transformer according to the user the quality of power supply and the load harmonic component, designed to take full account of the nonlinear load, and considering the influence of harmonics on the iron core, the coil performance, according to the standard design and manufacture, can effectively ensure the reliable operation of the isolation transformer in UPS system.
