Page 5: Operating Modes And Applications
3. OPERATING MODES AND APPLICATIONS The ESY1 devices are electronic analog regulators of single-phase AC voltage, which use the phase-cutting principle (Triac) in order to vary the output active voltage applied to a resistive or inductive load. When connected to asynchronous high-slip electric motors of fans or pumps, they control their rotational speed in order to maintain the key parameter within desired values. -
