263

263 is a 200 series voltage monitor. The voltage monitor assures that operating voltage remains within a range set by two independent adjustments: upper and lower voltage settings. It controls supply voltage for equipment sensitive to supply tolerance and offers protection against under- and over-voltage conditions. It is approved by EN 60255-6, EN 61010-1, UL standards.
