Product Description

Principle

The CHB_CAB series current sensors are suitable for EV battery monitoring applications, providing high accuracy and extremely low zero error. When measuring, the primary side (high voltage) and secondary side fully insulated (12V system)
* Closed- loop
* Supply voltage: DC +12 V
* 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
