Model: SD194E-9S4 LED display multi-function power meter
Model: SD194E-9Y4 LCD display multi-function power meter
Accuracy: For current and voltage RMS measurement, the accuracy class is 0.5.
For active, reactive, apparent power and frequency measurement, the accuracy class is 1.0.
For four quadrant energy metering, active power accuracy class is 0.5, and the reactive power accuracy class is 1.0.
Input net: 3 phase 3 wire system, 3 phase 4 wire syetem (Frequency range 40~60Hz).
Input current: Rated input value AC 1A or 5A (It should be marked when ordering), sustained over load 1.2 times, instantaneous overload 2 times/10S.
Current ratio: The users can set the CT transformation ratio (3 phase ratio is changed at the same time). The meters should be used with a current transformer of connecting CT outside which the secondary current is 1A or 5A.
Input voltage: Rated input value AC 100V or 400V (It should be marked when ordering), sustained over load 1.2 times, instantaneous overload 2 times/10S.
Voltage ratio: The users can set the PT transformation ratio (3 phase ratio is changed at the same time). The meters should be used with a voltage transformer of connecting PT outside which the secondary current is 100V or 400V.
Rated auxiliary power supply: AC/DC80~270V Frequency 50/60Hz.
Output: RS-485, MODBUS-RTU agreement.
Pulse out: 2 way eletric energy pulse output with optocoupler isolation.
Product features: This series meters are muti-function intelligent instrument, which have programmable measurement, display, digital communication and energy pulse output. The meters can complete the electrical measurement, electric energy measurement, data display, collection and transmission. And it can be widely used in substation automation, distribution automation, intelligent building, enterprise internal energy measurement, administration and assessment. Meanwhile, it based on MODBUS-RTU communication agreement to realize the LED or LCD field display and remote RS-485 digital interface communication. The installation uses high strength iron clamps which tight by nuts that make it have a long life time.
