Voltage Band Monitor
The Model 2681 Voltage Band Monitor offers essential protection for industrial systems. This device precisely monitors both over and under voltage conditions, safeguarding equipment from potential damage due to power fluctuations. Its automatic reset function ensures continuous operation without manual intervention after a voltage event, minimizing downtime. Available in both AC and DC versions, the 2681 accommodates diverse application requirements, supporting nominal voltages from 24vac to 240vac and 12vdc to 230vdc. With a robust SPDT output and a 10A contact rating at 240vac resistive, it provides reliable control for connected loads. The unit's compact design and wide operating temperature range from -20° to +122°F make it suitable for various industrial environments, contributing to system longevity and operational stability. Its set-point stability of ± 0.5% ensures consistent performance.
