AC current transformers

AcuAmp AC transformers feature a larger than average sensing window and a split-core case for convenient installation over large wires or bus bars without disconnecting; secondary terminals are zinc-plated for added reliability. The compact design saves space in control panels by remotely locating the sensing of the current closer to the load. The transformers are compatible with standard power monitors and panel meters designed for 5A input, and produce a 0–5 A output proportional to the current flowing through the sensing window.
