♦True RMS AC+DC current measurement
♦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
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.
