- Company Profile
RDQ3NM?Series Advantages: 1. There is a reliable mechanical interlock device and electric interlock protection between two MCCB, completely avoid the possibility of two MCCB closed at same time; 2. Intelligentized controller adopt the single chip microcomputer (SCM) as the control core, simple hardware, strong functions, easy extension, high reliability; 3. Intelligent controller circuit layout design adopt power sampling separate with SCM control, from the hardware to overcome the electromagnetic interference;? 4. With short circuit, over load protection functions, over-volt & under-volt,phase missing auto transfer function and intelligent alarm function; 5. Auto transfer data by external setting freely, with operation motor protect function; 6. Signal connecting cable have passed FLUKE instrument channel test, anti near crosstalk,attenuation crosstalk and back wave loss, can meet the test criteria for permanent link; 7. The ATS controller installation method provide customer with highly autonomy, ( split installation only need simply connect the attached RJ45 signal cable to the corresponding terminal port);
