Over the last decade, UST’s full line of industrial-grade electronic automatic voltage regulators have proven capable of reliably compensating for poor utility power. Thanks to UST, facility managers in developing regions (and those in urban areas in developed regions where the grid is stressed) can now count on perfect power.
This short video explains why modern electronic voltage regulators, like the UST MiniEVR™, should be specified instead of ferroresonant transformers in cases where the load is 2kVA or larger.
EVRs operate at up to 99% efficiencyat all times, while ferros typically operate at efficiencies of only 75% to 80%, and frequently operate at efficiencies as low as 50% – wasting electricity and generating unnecessary carbon.
EVRs run silent and cool and can be installed indoors or out, while ferros are noisy and hot and must be installed in a protected indoor environment.
EVRs are specified to match the load exactly, while ferros must be oversized by a factor of 2x to 2.5x.
