Highly reliable hall effect device.
Compact and light weight.
Fast response time.
Excellent linearity of the output voltage over a wide input range.
Excellent frequency response (> 50 KHz).
Low power consumption (12 mA nominal).
Capable of measuring both DC and AC, both pulsed and mixed.
High isolation voltage between the measuring circuit and the current-carrying conductor
(2.5 KV ac).
Extended operating temperature range.
Flame-Retardant plastic case and silicone encapsulate, using UL classified materials, ensures
protection against environmental contaminants and vibration over a wide temperature and
humidity range.
