RoCoil TCA-5. For use with DENT RoCoil CTs. Includes Low Voltage (120/240V AC) power supply for use on 1-phase services, wiring harness, and TS35/7 DIN rail. Does not include RoCoil 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.
