Principle    
CHK_EKB15D4 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.

Feature
 * Open- loop                                        * Supply voltage: DC +-12~15V
 * Capable measurement of currents: DC, AC,pulse with galvanic isolation between primary circuit and secondary circuit.

Advantages                                                  
* Easy installation                                    *  Can be customized
* No insertion losses                                 *  Low power consumption
* Wide current measuring range                       *  High immunity to external interference

Applications
* Inverter applications                                 *  AC/DC variable-speed drive 
* Uninterruptible Power Supplies (UPS)                 *  Switched Mode Power Supplies (SMPS)
* Frequency drive control home appliances              * Communication base station power supply detection (column head cabinet)                  
* Current measurement for master control, generator control and motor controller of electric vehicle
*DC transmission of smart grid
