2730-120Categories: 2730-Series, Current-Monitors
The Model 2730 Over/Under Current Monitor is designed to monitor a single AC current input for high and low current conditions. The solid-state circuitry drives two internal electromechanical relays. When operating power is applied, the unit will not respond to the current input for the duration of the ON delay. Normal operating current will leave the relays de-energized. A current drop below the LOW TRIP setting will energize the low current relay; a current rise above the HIGH TRIP setting will energize the high current relay. The relays may be interconnected to provide current band monitoring. Indicator LEDs show when a trip condition is sensed, and when the appropriate relay is energized. The trip and reset response times for the Model 2730 are set at one (1) second. Special adjustable versions are available on request. Current transformers may be used to extend the operating range of this unit.
