Topstek True RMS Current Transducer TMQ80A..1000A-CL420
Application Connections
TMQ-CL420 can be used with two types of connections. In both cases, the GND pin have no internal connection, and TP
Pin is for factory calibration only.
Connection 1:
The power supply is on the receiver side. Only two connector pins are used.
Connection 2:
The power supply is on the CT side. Make sure you have a proper ground connection to prevent grounding noise.
