3. Focus on measurement and protection of accurate systems


The LMK5 not only converts current, but also provides reliable measurement data to drive system decisions.


3.1 Provides a reliable signal for the protection system


This product is specifically designed to collect low voltage and short circuit overload signals and can work with Ray and Smooth to provide a variety of protection. Excellent transient response capability (e.g. dynamic steady current, which achieves 2.5 times the thermal steady current) ldyn) allows for signal input.


3.2 Guarantee of torque safety design


This product has good machine safety factor (FS<5) and meets strong international and domestic
standards such as IEC 61869-2 and GB1208-2006. The insulation level reaches class E(120℃), and has been tested for 3kV AC/1min resistance. Many safety barriers are installed inside to ensure that all accurate measurements are carried out under safe conditions.


4. Widely Available Situation


The flexibility of the LMK5 series allows you to handle multiple roles.


4.1 Tracking and control of industrial energy


Suitable for situations requiring testing, control, marking and recording of the operation of electrical equipment. It is the appropriate measuring element of plant automation systems and energy management systems.


4.2 Protection of critical equipment


Widely used in relay protection circuits of distribution systems, motors and other electrical equipment, it provides protection in front of equipment by accurate measurement negative currents.


4.3 Application to specific environments


This product is suitable for indoor environments where there is no direct intrusion of vines or eyes, severe pollution, severe vibration.It deals with a variety of situations.
