ATOSG-7KVA isolation transformer is a three phase unit with 7 kVA rating and primary voltage of 380V/220V AC on the primary side. This transformer has a secondary voltage of 208V/120V AC on the secondary side. It is designed for use in control circuits and general applications such as mechanical and electronic equipment, precision machine tool, CNC machine tool, lighting, etc..7 kVA Isolation Transformer Specifications
Note:Transformer can only convert voltage and CANNOT convert frequency.Transformer CANNOT convert single phase voltage to 3 phase voltage.Input/output voltage, power rating and whether with shell of all transformers, can be customized according to clients' requirements.3 phase Isolation Transformer Wiring MethodIsolation Transformer Application AreasTips: What circumstance the isolation transformer must stop running?
ATO step up/down isolation transformer should be stopped immediately if one of the following situations occurs:
