conditions: humidity not more than 50% at max.+40ºC, higher
humidity is allowed at lower temperature, at most wet month, the
average max humidity is 90% at the average min temperature +25ºC,
and have considered the condensation on the product surface due to
temperature variation. About ATSRDQ3NM Dual Power ATS is a
fully new product by our company organizes top engineers in two
years research and development, grand launch at the end of 2014,
completely subvert the traditional dual power ATS design style,
leading in the international industrial design concept in the
design process, from the product structure, appearance, ergonomia,
and control circuit etc., comprehensive improvement of the
traditional ATS, so as to make it has the quality of international
firs-class products and with high competitive price. 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, and
fire-fighting etc. Product accord with standard of IEC60947-6-1: ,
, , etc. Product StructureRDQ3NM 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 type
two 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. 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 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);
