power indicator light When main power voltage normal, this
indicator lighten 2 : Backup power indicator light When backup
power normal, this indicator lighten 3 : Main power ON indicator
light When switch on the main power position, this indicator
lighten; when during the switch recovery delay status, this
indicator flickering 4 : Backup power ON indicator light When
switch on the backup power position, this indicator lighten; when
during the transfer delay status, this indicator flickering. 5 :
Auto/Manual transfer mode control switch When switch on left side
is Auto transfer mode, on the right side is manual transfer mode 6
: Transfer delay time setting potentiometer ( Main power to backup
power transfer delay time )(A/C type without, B/D type have) When
ATS is on main power ON position, if main power fault and backup
power normal, controller start the timing ( the time setting by
transfer delay potentiometer), after the timing is over then
controller start transfer to the backup power supply; When setting
longer time delay can avoid switch transfer due to power grid
instant voltage drop ( for example, there is a big size motor start
in the same power grid, will cause the voltage drop in a short time
period) 7 : Recovery time delay setting potentiometer ( Backup
power to main power transfer delay time) (A/C type without, B/D
type have) When ATS is on backup power ON position, if main power
recovery and normal, controller start the timing ( the time setting
by the recovery delay potentiometer), after the timing is over then
controller start transfer to the main power supply About
ATSRDQ3NX-A/B/C/D series ATS is our company introduced to the
market on 2009, effectively solved the problems of MCB type ATS 's
insufficient functions, poor reliability, un-convenient replacement
etc., this product have three patent certificates ( Invention
patent, Utility models patent, Appearance patent), C/D series is a
new type introduced to market on 2010, this product have complete
functions, concept innovation, is a unique product among the
similar products. Product StructureRDQ3-63-A/B/C/D series ATS
comprised with two MCB and accessories, mechanical interlock
system, intelligent controller etc. Product have A, B,C,D four type
control construction, A type is basic type ( Only provide with auto
change auto recovery, phase missing protect, auto/manual control),
B type is intelligent type( including the A type functions and have
Generator start, fire linkage, time delay functions), C and D type
is improved type, increased three phase voltage monitoring function
on A and B type. This ATS series circuit breaker keeps the original
breaker's overload and short circuit protection function. RDQ3NX
Series Advantages:1. Product with modularized design, executive
unit, transmission mechanism, control circuit completely
independent, easy for replacement. 2. Mechanical transmission
device adopt gear transmission, completely eliminate the
possibility of closing at same time; 3. Compact appearance, it is
one of the smallest product on the market; 4. The control circuit
layout adopt working power and sampling power separate with single
chip control, to overcome the electromagnetic interference from the
hardware construction; 5. Working power voltage range: AC200-400V;
6. Less power consumption, max. peak power loss 4.8W, only 20% of
other similar products; 7. Product have complete functions, with
generator start, fire linkage, ON delay functions etc.; 8.
Modularized design, good components interchange performance, easy
installation; 9. Can use various executive circuit breaker;
Working ConditionsAmbient Temperature Max. +60ºC Min. -20ºC 24h
average not more than +35º
