Principle
CHK_LSP3S1L series Hall Effect Open Loop Current Sensor is a current measurement device which develops on base of the hall effect principle, wherein a Hall-effect device (HED) produces an output voltage linearly related to the amplitude and phase of a magnetic field applied to it.
* Open- loop
* Supply voltage: DC +3.3V~5.0V
* Capable measurement of currents: DC, AC,pulse with galvanic isolation between primary circuit and secondary circuit.
Applications
* Inverter applications
* AC/DC variable-speed drive
* Uninterruptible Power Supplies (UPS)
* Switched Mode Power Supplies (SMPS)
* Frequency drive control home appliances
* Photovoltaic (PV) current applications
* Solar Combiner Box
