55mm Opening Toroidal Current Transformer
The CTT0550 series of toroidal, panel mounted, solid-core current transformers offers highly accurate step-down transformation of the AC primary current with minimal phase shift to a level appropriate for micro-processor based circuits.
The current transformer features;
- Over current measurement capability.
- Broad frequency response range.
- A rugged design suitable for harsh environmental operating conditions.
- The secondary output can be configured either mV or mA.
