Introduction to three-phase full energy parameter acquisition module
Model: PD8073 - (xK) (xB)
I. Overview Designed and manufactured for the power monitoring needs of power distribution systems. Using high-precision energy ASIC chip, it can measure active, reactive, apparent, voltage, current, frequency, power factor, four-quadrant 21st harmonic energy, double pulse output, phase sequence detection and so on. Equipped with RS485 communication interface for remote operation.
The data type bit is a 32-bit floating point number, no conversion is required, and the MCU, Kingview, and PLC can be used directly.
Optional alarm output, optocoupler isolated output, used to connect PLC, microcontroller. The photoelectric isolation bi-directional thyristor output can directly drive the AC contactor and has a zero-crossing trigger function.
The module can directly replace the conventional power transmitter and is suitable for the energy efficiency management of the incoming line cabinet, generator set and base station. Can be connected to PLC, Kingview. Provide a sample of the Kingview 6.53 project.
Everyone:
Our advantage. We are not afraid of the goods.
1: The power supply can be AC85-265 DC10-30V DC24-72V AC85-450V. Maybe you have to ask, why are you so many choices? The DC24-72V is used in the communication base station because the backup battery is 48V; the AC100-450V is used for phase voltage supply (no zero line), and the generally designed switching power supply cannot withstand it.
2: Using a dedicated power chip, 24-bit sampling (floating point). Other manufacturers are generally 16-bit samples (integer).
3: The sampling speed is fast, sampling once every cycle, 50 times per second.
4: The data type is 32-bit floating point number, without any conversion, MCU, Kingview, PLC can be used directly. The data format of many other manufacturers is shaping, and the different variables are set to different decimal points. This is very troublesome when using Kingview and PLC. It requires different variables to be converted according to the decimal point. In short, a lot of calculations are needed.
5: The electric energy is not lost and is permanently stored. No matter how the power-off test is conducted, there will be no loss or data confusion. Some manufacturers' products are cleared after the power is turned off. Some of them frequently lose power, and the data is confusing, and the power becomes amazing.
5: There is phase detection function.
6: Optical isolation 485 interface, the interface can resist AC380V access for 2 minutes without damage. Other manufacturers do not have this protection design.
7: Optional 1 channel alarm output, 8A600V bidirectional thyristor or optocoupler output. Alarm or transmission output, all set according to the percentage of the range, the parameter structure is completely unified. The alarm output has a “hysteresis parameter” setting. His meaning is: for example, UA range 220V, upper limit alarm point 110.0%, hysteresis 5.0%, delay 2 seconds, then the action will be as follows: continuous greater than 242V for more than 2 seconds, The alarm is output; once the alarm occurs, the voltage is lower than 242-11=231V, the alarm is released.
8: Powerful, almost all power parameters are available. The ratio of PT and CT, including electrical energy, can be processed by the meter, and the obtained data is the actual data of electricity consumption. You can also choose not to multiply.
All other manufacturers, if the data type is a 16-bit integer, can not complete the multiplication function. For example: If CT = 120 times. 65535 stands for 65.535A, then 5A x 120=600A, which is not represented by a 16-bit integer. and so. Many manufacturers have said in the manual: to users to take their own. This also means that if the variable IA is defined in the configuration king, it is an integer type, but the actual IA is equal to (communication integer value) /1000 * CT (ratio). Ladies and gentlemen: A lot of variables have to be done this way. Very tired. For PLC multi-chip microcomputer. And we use standard floating point numbers, as long as the definition of IA is FLOAT. For details, please refer to the "Instrument King King 6.53 Project File" and "Instrument MODBUS Quick Application Guide" provided by us.
9: Independent property rights, you can modify the program for you, and compatible with any existing system. You can guarantee that you can directly replace other manufacturers' equipment without modifying the main control program.
