Automatic Changeover Switch Load Transfer Switches for Generator Switches (RDQ3NMA)
Radin Electric provides ATS design, engineering, and full after
sales support for a wide range of automatic transfer switch
applications. We offer onsite electrical audits to assist in
determining the correct product and installation to meet your exact
needs and requirements.
1. About ATS
RDQ3NM series intelligent dual power auto transfer switch (brief as
ATS) suitable for emergency power supply system with rated AC
voltage 400V, 50/60Hz. When one power source fault, can auto
interchange from main power to backup power, no need manual
operation, to protect the power supply stability. Mainly apply to
the important place which not allow power cutoff such as Hospital,
shopping mall, bank, chemical industry, metallurgy, high building,
military facilities and fire-fighting etc.
2. Product Structure
RDQ3NM series intelligent ATS comprised with two 3P or 4P MCCB and its accessories (Aux. contact,Alarm contact), Mechanical interlocking transmission mechanism, intelligent controller etc. Have integral and split typetwo structures. Integral type is controller and executive unit installed at a same base; Split type is controller installed on the panel and the executive unit installed on the base inside the panel box, a 2m length signal cable connecting the controller with the executive unit.
3. 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);
