Isolation transformer design serves as an alternative to installing dedicated circuits and electrical upgrades. Remove EMI/RFI noise, utility switching transients, background spikes, and power, problems generated by other onsite loads, utility grid-switching, and lightning related surges. Surge suppression components offer continuous line filtering of a full range of power line noise in all modes. Transformers feature NEMA 5-15P input and NEMA 5-15R output outlets.
