Product Description

Principle

DC Leakage Current Sensor develops based on magnetic modulation closed loop principle, to measure tiny current (mA level). DC leakage current measuring range can reach 0~±200mA. 
This sensor is used to measure current of signal system, circuit, and leakage monitoring system, as well as to measure current differential.
* Electromagnetic induction closed loop principle          
* Apply unique patented technology for measure tiny current (mA level)     
* Supply voltage: DC ±12~15 V 
 

Advantages

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

 

Applications

* The current detection of the lift
* DC panel detection
* The signal system 
* Current differential detection
* AC variable-speed drive/ Servo drive 
* UPS and Inverter applications 
* Leakage detection
* Circuit detection         
* Insulation Resistance test
