Thee Phase Isolation Transformer with Connector is used in varied industries for voltage control and stabilizing current flow by connecting phases and is available in voltage range from 10 V to 5000 volt. The Transformer has frequencies up to 25 Hz to 500 Hz and works effectively in reducing the impact of power hassles like surges, noises, short-circuits, high or low voltage etc. The Transformer protects CNC machines, computer and telecommunications equipment from damage due to electrical noise, spikes etc. The Transformer has leakage current of less than 20 micro amps and common model attenuation of 100 db. The Transformer ensures efficient services where ground potential of system units is different from each other and is exposed to the effects of instability at high frequencies. The Transformer work when no small current leakage is permitted in the equipment. The Transformer is used to protect against strong lighting, impulse noise, bus short- circuit, accidental discharge of capacitors etc. The Thee Phase Isolation Transformer with Connector has insulation strength of more than 1000 mega ohms and coupling capacitance of 0.1 PF for 1000 db.
