YCQ1F series excitation type Automatic Transfer Switch (ATS)
YCQ1F series excitation type Automatic Transfer Switch (ATS)
General
The YCQ1F series automatic transfer switch consists of a load isolation switch (without overload and short-circuit protection mechanism) and an intelligent controller. The switch adopts an excitation type transfer mechanism, which
provides faster switching speed. It also employs a new microcomputer control system for intelligent monitoring and control, strong electromagnetic
compatibility, long-term continuous operation, and stability and reliability. The
split-type product can be equipped with an LCD display controller, which is easy to operate, has clear indications, and provides a user-friendly human-machine
interface.
The YCQ1F series automatic transfer switch is suitable for single-phase two-
wire/three-phase four-wire dual power supply networks with AC 230V/AC 400V rated operating voltage and rated current up to 630A. It is used to disconnect the load circuit from one power source and connect it to another power source. The transfer switch has self-action and optional manual operation features.
Standards: IEC 60947-6-1
Features
The product consists of two parts: the switch body and the intelligent ATS controller. The switch body with an electrical and mechanical interlock. The product used solenoid actuate, double wire loop DC pulse operation, The
operation power of the conversion controller adopts the line voltage 220V of main standby power supply.No additional control power.
Type designation
Operating conditions
1.Ambient air temperature
Limit of temperature: -5℃ ~ +40℃ .
The average no more than +35℃ within 24 hours. 2.Transportation and storage
Limit of temperature: -25℃ ~ +60℃,
The temperature can be up to +70℃ within 24 hours. 3.Altitude ≤ 2000m
4.Atmospheric condition
When the temperature is +40℃, the air relative humidity should not exceed 50%, only under lower temperature can allow for higher relative humidity. If the
temperature is 20℃, the air relative humidity could up to 90%, Special measures should be taken for occasional condensation due to humidity changes.
5.Pollution level: Grade 3
6.Electromagnetic compatibility: Environment B
