Product Details

D129072 is a split core (open core) current sensor for EV Charging Pile Station. Its structural design ensure fast speed load and unload under constant power, which is greatly improve the construction efficiency. The contact surface of iron core is machined by mirror surface, ensures that the contact surfaces are more compact and restless. widely used in smart meter, smart grid, monitoring device, EV charger, circuit protection, and machine equipment etc. 


D129072 China Supplier High Accuracy 100A Split Core CT Current Sensor with RS485


1.With M-BUS communication, current and temperature values can be read.(voltage,current,Kwh can be customized)

2.Split core structure, without destroying circuit, low cost, easy installation, machined by mirror surface, the contact surfaces are more compact and restless.

3.Alarm output function:Overheat alarm/overcurrent alarm. With the output function of over current or over temperature alarm, by setting the upper limit of the current or temperature.
