Product Description

Principle

CHK_BR15S4 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 +15.0V
 * 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
