VAKE120A-side

chartProvides protection to equipment that is required to operate within an upper & lower AC single phase or DC voltage limit. As long as the operating voltage remains within an OVER & UNDER voltage range, the internal relay stays energized. If the operating voltage falls outside this range, the relay will drop-out. The Umax dial sets the upper limit per the OVER voltage range of the product. The Umin dial sets the lower limit at 30-95% of the upper setting. This product has an adjustable time delay on drop-out of 0.1-10 seconds, which is provided to prevent nuisance tripping.
