Product Overview
ASKQ8 series transfer switch ( referred as "TSE" ) are usedin 50Hz, rated voltage 400V, rated current to 6300A emergency power supply system.TSE is a dedicated transfer switchthat interrupts power to the load during switch the power. Interlocking reliable , compact structure, long service life, easy installation and maintenance, operated manually or electrically. It can be widely used in the various occasions of unsustainable power.
The combination of TSE and controller becomes automatic transfer switch (ATSE).When main power is lack of phase, overvoltage and undervoltage, according to the setting delay time automatically switch the load from the main power to standby power , the controller can set two operating procedures:
Auto Switch and Auto Recover 2. Auto Switch but Not Auto Recover.
TSE standard : GB / T14048.11 Low-voltage switchgear and control equipment.
Use Environmental Requirements
1. Ambient air temperature: Ambient air temperature does not exceed +40 ℃, and its average temperature within 24h does not exceed +35 ℃.
2. Atmospheric conditions: When the maximum temperature is +40 ℃, the air relative humidity does not exceed 50%, at lower temperatures allows higher relative humidity, for example, when +25 ℃, it is up to 90%, due to temperature changes caused by condensation should Take special measures. ő Altitudeǖ Altitude of installation site is not more than 2000m.
3. Pollution level: TSE corresponds to GB/T14048.11 pollution Standard level 3.
4. Installation category: TSE corresponds to GB/T14048.11 Standard installation Ⅲ.
5. Installation conditions: TSE can be vertically installed in the control cabinet, distribution cabinet.

Precautions
1. please avoid installation in high temperature, high humidity, steam, harmful gas and powder occasions.
2. Switch-in action and trip action are completed within 0.3s. To ensure reliable completion of the action, control instructions should be maintained above 0.5s.
3. If "switch-in" instruction and "trip" instructionare inputted at the same time at power side, switch-in statewill be remained, the coil will continue to be excited, so please avoid inputting "switch-in" instruction and "trip" instruction at the same time.
4. Please electric operation, try to avoid manual operation.
5. During DC operation, if the power supply circuit has a voltage drop device, do not pull the power supply from the output of the device, and should be directly from the DC power supply.
6. The power supply capacity of the control circuit and the cross section of the connecting wire should be large enough, the connecting wire should not be too long. DC operation should pay attention to battery capacity.
7. TSE for instantaneous excitation , the control power switch after the completion of the internal switch off, so the control power does not need to use auxiliary contacts to cut off the control power.
