Automatic transfer switch controller RDQ3NX series

Basic Structure This controller is a simple controller developed as per to market demand, have the features of simple operation, suitable functions and display intuitive etc. Characteristic Modularized installation mode with main body. A, C type controller all have under voltage and voltage missing monitor function. A, C type controller all can arbitrary interchange with single phase and three phase circuit. A, C type controller all have Auto/Manual two working mode. Basic Structure This controller is a multi-function electric monitor device, it is a collection of monitor, analysis, control, protection etc many functions as a integration, widely used in highly automation genset control system and electric power automatic control system. Characteristic Setting the controller working mode and transfer delay time through the pull switch. Fire linkage control function: B type controller with a set of passive fire-fighting signal input terminal. The input signal using opto-coupler isolation, have strong anti-interference ability; And also have a set of passive feedback signal output terminals, can send the switching position back to fire-fighting control equipment. Generator start/stop control function: Controller with a relay contact point to control the generator start and stop. D type based on B type single phase voltage monitoring change as three phase monitoring. Technical Data • Working voltage range: AC150~265V • Ambient Température: -2CTC -+60^ • Power consumption: <5W • Transfer delay: 0s~30s adjustable • Recovery delay: 0s~30s adjustable
