RDQ3NM series
intelligent dual power auto transfer switch (brief as ATS) suitable
for emergency power supply system with rated AC voltage **0V,
*0/*0Hz. 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. Product accord with standard of
IEC********1: etc.
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
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 andintelligent 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 RJ*5 signal
cable to the corresponding terminal port);
