One, Outline
Monitoring requirements for power supply and distribution system design and manufacturing. High-precision powerASICChip measure active, reactive , apparent , voltage, current, frequency , power factor, four -quadrant21Harmonic power , dual-pulse output , phase sequence detection. WithRS485Communications interface for remote operation.
Data for 32 -bit floating-point type , without any conversion , SCM, Kingview , PLC can be used directly .
Optional alarm output, opto isolated output for connectionPLCSCM . Optically isolated triac outputs can directly drive AC contactor with zero trigger function.
Module can directly replace conventional power transmitter for line counters , generators, energy management station . Yes, Kingview connection with the PLC. 6.53 provides a sample configuration king project.
Members :
Our advantage. We are not afraid of confinement .
1 : Power supply options are AC85-265 DC10-30V DC24-72V AC85-450V, you might ask, why are so many choices? This DC24-72V used in communications base stations, because there is a spare battery 48V; AC100-450V used in this phase voltage supply ( without neutral) , the general design of the switching power supply can not afford.
2 : using a dedicated power chip , 24 samples ( float ) . Other manufacturers generally are 16 samples ( integer ) .
3: The sampling speed , sampled once per cycle , 50 times per second.
4 : 32-bit floating-point data type , without any conversion , SCM, Kingview , PLC can be used directly . Many other manufacturers to do the data format is shaping different variables set different decimal point. So when Kingview , PLC with very troublesome, in accordance with the needs of different variables decimal conversion , in short, needs a lot of calculations.
5: Electrical energy is not lost , permanent preservation. Whatever power failure test , the data will not be lost or confused . Some manufacturers of products powered down after power is cleared. Some frequent power outages , the resulting data confusion , power has become a big amazing.
5: The phase sequence detection.
6 : 485 opto-isolated , anti- AC380V interface can access two minutes without damage . Other manufacturers do not have this protection design.
7 : Optional 1 alarm output , 8A600V or optocoupler triac output .Alarm or transmitter output, all in accordance with the percentage range of settings, parameters structure is completely unified . Alarm output has " hysteresis parameter " setting, his meaning is : for example UA Range 220V, high alarm point 110.0% , 5.0% hysteresis , delay 2 seconds , then action will follow the following rules : Continuous greater than 242V more than two seconds , output alarm ; once an alarm occurs , the voltage is lower than the 242-11 = 231V, only disarm the alarm .
8 : powerful, almost all of the energy parameters are. PT, CT ratio , including the electric energy can be processed by the instrument , the data is the actual data obtained electricity . You can also choose not to take .
All other manufacturers, if the data type is a 16-bit integer , are unable to complete the multiplication function. For example : if CT = 120 times . 65535 representative 65.535A, then 5A x 120 = 600A, with a 16-bit integer can not be expressed . And so. Lane said many manufacturers instructions : To take your own . This also means that if the variables defined in the configuration king IA, he is an integer type , but the actual IA should be equal ( communication integer ) / 1000 * CT ( ratio ) . Members : Many variables must be doing things like this . Tired of it. For more microcontroller PLC . And we use a standard float, as long as the definition of IA FLOAT get away . For details, please refer to " instrument configuration king 6.53 Project File" and " Meter MODBUS Quick Application Guide " we offer.
9: own property , you can modify the program , and is compatible with any existing system . You can ensure that you do not modify the master program in the case, a direct replacement for other manufacturers equipment.
