Introduction
Isolation Transformers have primary and secondary windings that are physically separated from each other. It offers hundred percent isolation from the input AC line. It reduces the cumulative leakage current of the isolator and connected equipment. Secondary neutral to ground bonding virtually eliminates common mode noise, providing an isolated neutral- ground reference for sensitive equipment. This is also known as 'insulated' because the windings are insulated from each other. Isolation transformers remove EMI/RFI noise, utility switching transients, and harmonics generated by other onsite loads and utility or lightning related surge conditions.

Hundred Percent Isolation
Built-In Electrostatic Shield
Eliminates Common Mode Noise
Removes Transient Noise
Attenuates Voltage Spike & Surge
Reduces Leakage Current
Improves Power Quality

Shielded isolation transformers have all the feature of the standard isolation transformers
plus it also incorporates a full metallic shield between the primary and secondary windings.
This electrostatic shield 'faraday shield' is connected to earth ground. It attenuates (filters)
voltage transients (voltage spikes) and filters common mode noise. The shielded isolation
transformer is preferred over a standard isolation transformer because it provides protection for sensitive and critical equipment and vastly improves power quality. Additional surge suppression components placed at the line input and output combined with full line
isolation offers continuous filtering of a full range of power line noise in all modes.
