1.The dual-power automatic transfer switch (ATS) is a newly
developed miniature household power transfer switch, is mainly used
to test whether the main power or reserve power is normal.
When the normal power supply is abnormal, the reserve power supply
will start work immediately to ensure continuity, reliability and
safety of the power supply. It is specially designed for household
rail installation for PZ30 distribution box.
2.The ATS is suitable for emergency power supply systems of AC50 or
60Hz and rated voltage 400V. It is featured with firm structure,
reliable transfer, easy installation and maintenance, and long
life, is widely used in places where frequent power outage is not
allowed. Both electric and operation and manual operation are
available. The ATS is composed of TES and controller.
3.According to the standard GB/T14048.11 Part 6-1: Multiple function
equipment - Transfer switching equipment, we can know that ATS is
the most suitable low-voltage switchgear and control device.

Normal running time and installation conditions
1.Ambient air temperature
Temperature should be within -5℃~40℃, and the average temperature
within 24h should not exceed 35℃.
Altitude of the installation site should not exceed 2000m.
The relative humidity of the installation site should not exceed
50% at maximum temperature 40℃, and it will be higher at minimum
temperature -5℃, for instance, 90% at +20℃. Please take measures
for the dew on product surface caused by temperature change.
4.Class of pollution
Pollution class of ATS meets the specified level of GB/T14048.11.
Installation category of ATS meets the specified category in
Matterts need attention
ATS with automatic operation can ensure power generation and
power-off performances, but for ATS with manual operation , it
cannot ensure the above performance due to the speed of power
generation and power-off or operator differences. Excessive silver
alloy loss may occur during manual power generation and power down.
Therefore, set the selector switch at the manual position under
normal condition, and pull it to the manual position when all power
is turned off to check and maintain the operating system and
contacts. After the manual operation is completed pull the selector
back to the automatic position.
ATS will be active in an instant. After the conversion is complete,
the coils in the control circuit are disconnected by the internal
converter. The coil can operate normally with a rated voltage of
80%~110%, and too low voltage may cause the coil to heat up or even
