AC Ratio Decade Transformers

Active

AC Ratio Standard, 7 Decades

Buy Datasheet

AC ratio decade transformers are critical tools for precise calibration and testing of electrical equipment. Engineered to provide accurate voltage and current ratios across a range of values, they offer unparalleled accuracy and linearity calibrating and verifying electrical parameters. With ratios selectable through rotary switches, they enable precise simulation of a large variety of values.
