Product Description

Principle

CHK-LSV5S2L series current transducer is a fully integrated linear Hall-effect current
sensor. Internal circuit adopts ASIC packaging technology products, which is debugged by software. Horizontally-mounted sensor makes space saving possible for the application.

 * Open- loop
 * Supply voltage: DC +5.0V
 * Capable measurement of currents: DC, AC,pulse with galvanic isolation between primary circuit and secondary circuit.

Advantages

* Excellent accuracy
* Very good linearity  
* Low temperature drift
* High immunity to external interference
* Optimized response time, no insertion losses 

Applications

*  Photovoltaic (pv) current applications
* AC/DC variable-speed drive 
* Switched Mode Power Supplies (SMPS)
* Uninterruptible Power Supplies (UPS) 
* The  applications of inverter
