CONTROL DEVICE power quality parameters

摘要

quality control apparatus power parameters, comprising: a first analog-to-digital converter, the system controller coupled to a keyboard, a real time clock, block RS-232C interface, the interface unit IEEE 1284 and also connected via the system line to a digital signal processor, means for displaying information, a permanent storage device, characterized in that it introduced three identical input transducer, which inputs information on the monitored signals are fed strain respective phase control inputs of the input transducer through the inputted block galvanic isolation are connected to the system controller refinable outputs, data inputs and whose control signals are connected through block galvanic isolation to the control circuits and the outputs of respectively the first, second and third analog-to-digital converter, the inputs of which are fed signals from respective outputs of the input transducers, and to the system controller is further connected to a block interface RS-4 85 and through the line system FLASH - memory, high-speed random access memory and volatile random access memory.
