CU series Current Sensors provide a reliable and low cost solution to monitor
current of supply/exhaust fans, pumps, compressors, unit ventilators, lighting
or any equipment. Current Sensors are available with a solid core or split core
configuration for ease of installation. Two models are available with field
selectable ranges to cover 10 amps to 200 amps full scale. The current sensors
incorporate sophisticated electronics to provide true RMS measurement from
20 to 100 Hz frequency. The VDC output sensor is self powered and does not
require external power. The 4-20 mA sensor is 2-wire loop powered and can
handle 15-40 VDC. 5 year warranty, UL listed, CE certified and the lowest cost
in the industry are some of the features which make the sensors an ideal solution for load status monitoring and alarming functions.
