Dent 5A Rope Kit w/Low Voltage Power Transformer – RōCoil TCA-5-LV-KIT
Finally a 5A rope product on the market! 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 RoCoil TCA-5 has four selectable current ranges: 500, 1000, 2500, and 5000A. The range is changed using a switch on the front of the device. A separate switch on the front is used to change the frequency between 50 and 60 Hz.
The wire that connects the RoCoil TCA-5 to the power meter is supplied by the user. Linearity and precision are maintained by using the correct output wire size.
The maximum allowable output impedance (or burden) of 50 mOhm plays a critical role in the selection of output wire size and the allowable distance between the power meter and the RoCoil TCA-5. See data sheet for the Output Impedance/Burden Table.
The RoCoil TCA-5 requires an external 48 VDC power supply for operation. Two versions of the power supply are available: a 120/240VAC “low voltage” version and a 200/500VAC “high voltage” version. This product is the low voltage version for use with input power of 120/240Vac. See TCA-5-HV-KIT for the high voltage version (200/500Vac input).
The unit can be DIN or panel mounted and a 10″ section of TS35/7 DIN rail is included with the kit.
