Bypass regulator UPS bypass cabinet 60KW/100KW regulator
Overview
ES-ZW series non-contact voltage stabilizer is a new generation of non-contact AC stabilized power supply developed and produced in response to the high requirements of high-precision equipment on the market for power grids; it has a fast response speed and voltage stabilization accuracy. High, no contact, no wear, no interference, complete protection functions, fully automatic, maintenance-free, three-phase voltage adjustment and automatic balance; using large-scale integrated circuit control core, fully automatic operation, complete protection functions, no
personnel on duty.
This series of regulators retains all the advantages of mechanical compensation, parametric and magnetic compensation regulators, and specifically avoids the shortcomings of mechanical compensation, such as slow dynamic response, easy wear of carbon brushes, and ignition, and overcomes the parameters The inherent shortcomings of the voltage stabilizer are poor load adaptability, low efficiency of the magnetic compensation type voltage stabilizer, and large harmonic content.
Since its listing, it has been widely used in processing and manufacturing, rail transit, medical equipment, communications industry, equipment testing and other fields, and has won unanimous praise from users.
