RDS2 series Auto changeover switch mainly used for distribution or
electromotor network under 50Hz, rated voltage 380V, rated DC
voltage 220V, and rated current 16A to 3200A, change over between
main power and backup power, mutual work as backup power system and
city power and Generator power. At the same time, it can act as
disconnector for the un-frequency ON and OFF circuit or lines.
Such product are widely used in the power transmission and
distribution system and atomization system of important site which
power off is not allowed, such as fire-fighting, hospital, bank,
high buildings etc.
RDS2 Auto Transfer Switch Equipment (ATSE), is integrate the switch
and logical control together, no need extra controller, is an
electromechanical integration auto transfer switch, with voltage
monitoring, frequency monitoring, communication port, electrical
and mechanical interlock functions etc., can achieve auto control,
remote motor control and emergency manual control.
Operation is achieve by logical control board with various logical
commands to managing the motor, gear-box running, motor with spring
energy storage, instant release accelerating mechanism, quickly
open and close the circuit or make quick transferring, through
visible status to make sure the safety isolation, greatly improved
the every electrical and mechanical performance.
RDS2 ATS integral designed with metal case, compact and strong.
RDS2 ATS, the control part is with metal cover, switch part with
DMC case, have strong dielectric performance, protection
performance and reliable operation safety.
The switch suitable for auto transfer between main power and backup
power system or two load equipment's auto transfer and safe
The switch has beautiful appearance, novelty, small size, complete
functions, is the best choose among the similar products.
RDS2 series product have passed the EMC test.
It adopted double complex contact/ horizontal pulling
mechanism/micro motor energy pre storage and micro-computer control
technology, basically come to Zero arc ( no arcing chamber);
Adopted reliable mechanical interlock and electric interlock,
executive unit adopt independent load disconnect switch, it makes
more reliable and safety;
Adopt "Zero Position" technology, it can force to set to Zero
Position under emergency situation ( cutoff two way power supply,
meet the fire linkage requirements;
Load disconnect switch change over adopt singleness motor drive,
switch over smooth and reliable, no noise, little impact;
The driving motor have instant current across only under the load
disconnect switch change over, stable working status no need to
provide the working current, outstanding energy saving.
Executive load disconnect switch have mechanical interlock, make
sure the Normal power and Reserve Power working reliable and no
Distinct ON and OFF position indicator, padlock function etc., make
reliable and safe isolation between power supply and loading.
High security, high automatization, high reliability, working life
more than 8000 times;
Electromechanical integration design, accuracy change over,
flexible, smoothly, adopt international advanced logical control
technology, high anti-interference ability, no interference
Have main power ON, backup power OFF; main power OFF, backup power
ON; main and backup power OFF; three working mode (I-o-II);
Easy installation, control circuit adopt plug type terminal
Four operating functions: Emergency manual, motor remote control,
emergency OFF under auto control status, auto control operation.
Basic Type Switch Control Characteristic
Suitable for two way main and backup power system, auto transfer
with auto recovery;
Can expand functions by outer connection;
Auto, Remote, Manual control functions;
Delay 0.5s signal detect, avoid miss actuation;
Under Auto control status have "O" position remote control;
Can with RS-485 communication port ( optional), according to
24h average not more than +35ºC
Altitude : Not more than 2000m
Atmospheric 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.
