reactive power auto-compensation controller
ApplicationThis series of controllers adopt the high-performance single-chip microcomputer as the basic hardware, fully utilize high-speed operated strength and logicjudgment of the computer to make them selves really been accomplished intelligent, digitally. It is the first-selected products for capacitance screen manufacture due to its advanced technology and perfect function, strong antii-nterference ability, reliable and stead uy branch exact compensation and aesthetic in look.
Function characteristicAdopt AC sampling technology.Digital integration, filtration.Adopting the control technology of the single-chip microcomputer, has realized the intellectualized of electric network reactive auto matic compensation.Strong anti-interference ability can resist 2000V interference pulse from power direct, and not cra shing, does not lose the data, it is reliable to run st eady.Digital display electric network power factors, over-voltage values, current etc. Various kinds of control parameter.With self-checking functions, it needn offer current mutual inductors ratio to compensate capacitor capacity, is suitable for different parameter automatically.Sampling signal phase sequence is distinguished and changed automatically.With two working mode of manual and automatic, convenient for user to install and debug.With over-voltage judgment display function that can cut off the group of the capacitor quickly. Concise man-machine dialogue, operating, debugging, simplicity direct-view.The input resistance of current sampling signal is smaller than 0.05 , it can be taken out from measuring loops directly.Service ConclitionsAltitude not higher than 2500m.Ambient temperature-25 ~+55 .Relative humidity 50%, and 40 90% at 20NO corrosive gas, inductive dust, and inflamm able and explosive mediumsin the ambiente nvionment.The mounting position should be protected against violent vibration.
