Low Cost Remote Current Indicator
The
CR2550
series Remote Current Indicators are designed as a low cost method for providing a visu- al 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.
