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

♦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:
