Fuji Isolation Transformer ( 3 - 500 ) kVA
Features & Benefits
• High insulating materials and special shield-ing techniques are credited for the common mode and minimizing transverse mode noise
• Designed with zig-zag construction, which nullifies the harmonic current
• The core and its magnetic properties are selected in such a way that it allows enough leakage inductance to provide normal mode power line noise, which is in sync with the transfer of fundamental power frequency. All the higher frequencies are blocked
Unique box shielding and other apt techniques are used which block the transfer of electronic noise
• Better regulation with low impedance effect
• Shield against strong lightening, impulse noise, bus short-circuit, discharge of capacitors, etc accidental
Shield for the Neutral Harmonic Current and connected equipment will not be affected by electrical noise, spikes, surges, etc
