POWER REQUIREMENTS The DENT RoCoil TCA-5 delivers the flexibility and ease-of-installation of the RoCoil current sensors to applications using power meters with 5A current transformer inputs. Used with standard RoCoil flex CTs, the TCA-5 is a three-channel integrating transconductance amplifier that translates the 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 a DIN rail or panel mounted device requiring an external 48 VDC power supply. The RoCoil TCA-5 has four selectable current ranges: 500, 1K, 2.5K, and 5K amps and selectable frequency for both 50 and 60 Hz systems.
