Fuji Electric Consul Neowatt Ultra Isolation transformers provide low inter winding capacitance and low leakage inductance as they are designed with split winding construction to give high attenuation and multiple shielding mechanisms to reduce low capacitance.
Ultra isolation transformers
Features & Benefits (Ultra Isolation transformers)
- Split winding constructions and bi-filer connections is made to reduce the overall capacitance of the winding
- High insulating materials and special shielding techniques have been used to minimize the noise
- The core and its magnetic properties are chosen in a way that displays enough leakage inductance, which in turn offers normal mode power line noise. This is in sync with the transfer of fundamental power frequency. All the higher frequencies are blocked
- Transfer of electric noise is blocked by Unique Box shielding and apt techniques
- Better regulation with low impedance effect
- Shield against strong lightening, impulse noise, bus short-circuit, accidental discharge of capacitors, etc.
- Shield for the microprocessor-based machines and equipment’s from damage due to electrical noise, spikes etc
