SAIPWELL/SAIP RS485/Modbus-RTU three phase 35mm DIN rail mounted multi-function smart energy meter
Functions
Measurement
Measure positive/negative active energy, has the function of automatically identifying and indicating the power direction.
Total, top ,peak, flat, valley energy are stored respectively.
The meter can save 3-month data, the freeze transfer date of the electric quantity is assumed to be 24:00 at the end of the month.
All the storage data will not be missed when the power is off, which can be saved more than 10 years.
Clock and time rate
Internal hardware clock, the clock error is within 0.5s/day.
Programmable setting top, peak, flat, valley four rates, day time can be set 8 time intervals, the min. time interval is 1 hour.
Display
7-digit wide temperature type LCD display.
Real-time data wheel display, cycle display time is 4s.
Power pulse uses red LED indicating
Four kinds of rate period top, peak, flat, valley are indicated by characters.
Output
Active power pulse output, used for checking and collecting electric energy.
Communication
Used for parameter setting and meter reading.
RS485 communication interface, MODBUS-RTU communication protocol.
Programming
Programming is set by the upper computer
Time date setting
Meter address setting
Rate period setting
Power reset setting
External and cutting size
Installation drawing
Three phase multifunction power meter adopts 35mm standard DIN-Rail installation method, as follows:
Wiring method
This series of three phase multifunction power meter supports direct input and via CT input two kinds of input methods.
Note: Actual wiring please subject to the actual wiring diagram of the meter, the variable 6 in 4P-1 wiring diagram means the optionality of reactive pulse and clock pulse. (it is assumed to be pulse output)
Typical application diagram
SP300-E/FC is three phase multi-rate active energy gauge.
SP300-E/FC has a pulse output, can collect the consumption of active energy, can realize DCS remote.
SP300-E/FC has RS485 communication function, ,can realize meter reading and programming setting function through the upper computer.
