Model 603 & 603D Series Split-core current transformer - Secondary voltage up to 5VAC

The 603 & 603D Split Core Current Transformers are designed for assembly to an existing electrical installation without the need for dismantling the primary bus or cables.

These transformers are intended for use with high input impedance devices that require signal voltages up to 5 VAC.

The output can be rectified and filtered for devices requiring DC input. The non-linearity and voltage drop of the rectifiers and filters must be considered in the choice of the loading impedance.
