Industrial Grade Isolation Transformer provides line isolation, noise filtering and search suppression for electronics in industrial, and office and network environments. The Isolation Transformer protects against strong lightening, impulse noise, bus short-circuit, accidental discharge of capacitors, etc. The Isolation Transformer protects micro-processor based machines and equipment from damage due to electrical noise, spikes etc. The Isolation Transformer is used in all industries that use electrical power and needs electrical isolation including the elevator industry, ship construction, steel industry, machinery manufacturing, etc. The Isolation Transformer has magnetic properties that are properly selected to provide sufficient leakage inductance. The Industrial Grade Isolation Transformer is designed with split winding constructions and bifilar connections to reduce overall capacitance of the winding.
