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);
