The CTT0200 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.
