2621-12VDC

The Model 2621 Voltage Monitor offers precise voltage supervision for critical industrial applications. Its switch-selectable relay operation allows for flexible control logic, accommodating both 'on low' and 'off low' scenarios. With configurable nominal AC voltages including 24VAC, 120VAC, 208VAC, and 240VAC, and DC options like 12VDC, 24VDC, 48VDC, and 110VDC, this device adapts to diverse power systems. A robust 10A at 240VAC resistive contact rating ensures reliable switching for connected loads. The unit maintains set-point stability within ¬± 0.5% and operates effectively across a 14¬∞ to +122¬∞F temperature range, tolerating 97% humidity without condensation. Its rapid 0.5-second trip response and 0.1-second reset time ensure timely system protection. The compact design and 8-pin socket mounting facilitate straightforward integration, providing consistent performance and protection for sensitive equipment.
