Current Output Options:
The TA module is used for converting the RCTi or RCTi3ph sensors to 1A or 5A current output. This makes the sensor compatible with existing 1A or 5A metering circuits. Unlike conventional CTs, these models have no open circuit hazards, making them suitable for installations in confined spaces.
New Compact 1A Output Model – RCT1A:
The RCT1A is a compact, all-in-one flexible current probe with 1A output, available in ratios from 100/1A to 50000/1A. This simplifies installation and eliminates the need for expensive LV/HV plant shutdown.
Available TA Current Sensors:
Models available from 100/5A to 10000/5A. Specify 50Hz, 60Hz, or 400Hz.
TA5V-5A Output Module:
Converts RCTi or IRF voltage output to 0-5A signal.
Bandwidth: 20Hz-200Hz.
Accuracy: <1.0%.
Power Supply: 24Vdc, 110Vac, or 230Vac.
All products are certified with CE, IEC, EN, ASME, or BS approvals, ensuring that RCTi and RCTi3ph Clip-On Current Sensors meet the highest safety and performance standards.
