Low Cost Remote Current Indicator

The CR2550 series Remote Current Indicators are a low cost method for providing a visual indication of electrical current flow. The indicators are factory calibrated to provide a preset turn-on point. The value of the turn-on point is determined by the customer and specified in the part number. Attached to the transformer is a high efficiency, bi-polar LED that illuminates when the current is above the turn-on point. The indicator is available as standard with 11 inch long leads and a red LED indicator. designed as a low cost method for providing a visual indication of electrical current flow. The current-carrying wire is routed through the window opening in the current sensing transformer. Attached to the transformer is a high efficiency, bi-polar LED that illuminates when the current is above the turn-on point. The indicator is available as standard with an 11 inch long lead and a red or green LED indicator.
