1、Soft computing metering solution
Self-patented metering algorithm with highcustomizability, availability and stability,ensuring the metering features reliable.
Real-time monitoring for meter precision when they are installed on-site. Events will be generated when precision error exceeds the limit.
3、Magnetic isolation technology
Using the same isolating transformer, it can not only provide the isolating power supply needed for the chip itself, but also for the bidirectional isolated communication, at the same time serving to read the clock with high precision and stability. Simplistic system design for full isolation.
4、Zero-crossing switch on/off
Switch on/off at zero-crossing point to prevent connection or disconnection with large current. The switch can be executed at the right time according to different load type, reducing transient electromagnetic phenomenon during switch on/off.
5、Battery leakage current self-detection
During meter's operation, the battery leakage current is monitored in real time. Alarms and events on over limit leakage current. Battery abnormality will be detected and reported immediately.
Revolutionary upgrade has been made for the traditional direct-inserted backlight. The columns and backlight are integrated independently with backlight source welded on PCB, while not reducing light intensity.
The sampling devices (relay/copper, instrument transformer) adopts the hardwire connection method to replace the traditional wiring and welding. This realizes the welding and production automation so that the products are more stable and consistent.
8、The sensory behavior of smart meter.
