Product Description:
1.Double circuit manganin shunts can overcome small linear range and poor angle and large residual magnetism problem of CT.
2.After a lot of verification,the U.S. super-micro-controller with stronger anti-jamming is used.
3.With calibration software, meters can calibrate on the spot. PCB board is concise.
4.Advanced algorithms, 0.1W accuracy.
5.It compares the power of neutral and live wire in real time. When the power of neutral is less than 4%, the fault LED lights. The main measurement circuit is as per the neutral.
6.It measures the electricity of neutral and live wire dividually.
7.If meter counters are faulty. It can read electricity of total,neutral and live wire via infrared transceiver. The agreement is Compatible with DL/T645-1997.
8.Strong expansibility: RS485 communications, wide measurement range, LCD or LED display.
