Constant Voltage Transformers
Constant voltage transformers (CVTs), also known as ferroresonant transformers, use a magnetic structure and a capacitor to limit currents, regulate the output voltage, and perform other power functions. General Transformer offers reliable, maximum-efficiency CVTs custom-designed to meet your application requirements.
Additionally, our Constant Voltage Transformers (CVTs) feature a fixed output voltage to readily provide line and load regulation within 3% or better—our ISO 9001:2015 certified CVTs feature compact, reliable designs with high isolation levels.
