True RMS 4-20mA Current Loop Output CT
TFC30P80A~1500A-CL420
Features
♦ Highly reliable Open Loop Hall Effect device
♦ Clamp on split core structure
♦ Faster response time than temperature sensing
♦ Excellent linearity of the output voltage over a wide input range
♦ VFD and SCR type waveforms current measurement
♦ True RMS output
♦ 4-20mA current loop output
♦ High isolation voltage between the measuring circuit and the
current-carrying conductor (AC3KV)
♦ Flame-Retardant plastic case and silicone encapsulant, using UL
classified materials, ensures protection against environmental
contaminants and vibration over a wide temperature and humidity
range
Applications
♦ Power measurement, power panel
♦ True RMS AC+DC current measurement
Options
♦ Plastic case material:
PBT+30%GF(white) standard and PC(blue) option
♦ Operating temperature range:
70°C standard and option 85°C available
♦ Connector type: specify –E or –M. If other types of connector
required, please contact factory for other possibilities.
–M: Molex 5045 type (2.54mm pitch)
