3Phase AC Current Transducer for Mining/Engineering Machinery

 

Descriptions

GS-AI3-50 is a 3 phase AC Current Transducer,which is specially designed for mining and engineering machinery. The measuring range can be 2000A AC, and output standard dc signals 0-5V DC, 0-10V DC, 4-20mA DC, Can-Bus etc. It can be connected with PLC or other monitoring device for control.

Features

1) Measure the three-phase alternating current;
 
2) Output DC analog or can bus data;
 
3) Good linearity, high precision, basically no temperature drift;
 
4) Impact resistance, high reliability;
 
5) Aperture: 50mm, overall dimension: l263 × W28 × h98mm;
 
6) Executive standard: GB / t13850-1998 (iec688-1992).
 

Application

1) Motor working current detection, motor start over-current overload protection, motor short-circuit current detection;
 
2) Isolation sampling of strong / weak current between main circuit and measuring circuit can be directly connected with PLC, etc;
 
3) Detection, feedback, control, monitoring.
 
Note: This product must be placed in the explosion-proof box / cabinet when there are explosion-proof requirements.
