Name: JYS-9S4-Y Multifunction Power Meter
Dimensions: Dimensions: 96x96mm opening size: 91x91mm
Features: 4-digit, 3-row LED digital tube display, through the switch can be displayed commonly used parameters such as power. In the rated voltage, reference frequency and COS ∮=1.0, When the load current is 0.001In, the meter can start and continuously measure the electric energy.When 115% of the rated voltage is applied, the current loop has no current and the meter has no energy accumulation and pulse output.

2, auxiliary power: AC / DC 80-270V. Power consumption: < 5VA
3, display:
(1) JYS-9S4 using 4 3 LED digital tube display, the instrument's power parameter display is a PT, CT measured the actual value of the power parameters, (ie: voltage = voltage ratio PT input voltage, current = Current ratio CT × input current value, display power = power value × voltage ratio × current ratio.) Through the panel switch button to switch the display voltage (at this time the first indicator light) UB, UC or UAB, UCA, UCA, etc. Unit V. LED K or M On indicates KV and MV. Display current (but the second display indication The first row, the second row, the third row of LED displays the contents of the IA, IB, IC readings, the unit A. Indicator K or M light that KA and MA real utilitarian (at this time the second Display indicator light) The first row, second row, third row of LED display contents represent P, Q, COS ∮, The unit is W, Var. Indicator K or M light that Kw, KVar and Mw, Mvar. Point over the display using the first row, the second row of LED display
(2) Communication: The serial communication port is RS485 baud rate 4800/9600 programmable setting.The communication protocol adopts MODBUS communication protocol
