Since pioneering the use of flexible RoCoil CTs in energy measurement. we have been asked to provide a flexible coil with a 5 amp output. We are pleased to announce that the RoCoil TCA-5 now fulfills this requirement in the marketplace. Those who use 5 amp current input power meters will now be able to take advantage of the easy installation and broad current range coverage offered by RoCoil flex probe CTs.

The RoCoil TCA-5 is a three-channel integrating transconductance amplifier (TCA) that converts the 131mV/1000A electrical output signal from the RoCoil current sensor to a 5 amp AC current. emulating a traditional current sensing transformer.

The RoCoil TCA-5 is factory-calibrated to work with DENT RoCoil CTs (131mV/1000A). The unit can be DIN or panel mounted and a 10" section of TS35/7 DIN rail is included with the kit.
