CFCQ5 Double Power Automatic Transfer Switch 3p/4p

CFCQ5 Double Power Automatic Transfer Switch(ATS) 3p/4p   
 
What is an Automatic transfer switch ?
 
The automatic transfer switch change over between two powers.One is noraml power and another one is reserve power.When the normal power is abnormal it will automatically change over to the reserve power.
When the normal power restored ,it will change over the load back to the normal power and cut off the reserve power.
 
Different ATS has different function :
 
Category one :They only have basic change over power function.
Category two :They do not only have the change over function ,but also have overvoltage,
undervoltage,lose phases protection,fire protection function and so on
Category three:Some ATS have controller.
 
APPLICATION
 
CFCQ5 Series double power automatic transfer switch is used in AC 50HZ, rated voltage below 690V. Two power supply system. It can make a automatic transfer between the common power and backup power but without manual operation. This switch accords with the following terms of national GB/T14048. 11 <<automatic transfer switch>>standards:
Operating mechanism have reliable electrical and mechanical interlocking, in order to prevent concurrent access to the common power and backup power.
 
CFCQ5, when the voltage of detected A phase and all the phases of the common power interrupt in a scheduled time, will switch to connect the load from common power to backup power, and when the common power goes back to normal, it will automatically connect the load to the common power(with phase failure protection function)
 
 
TECHNICAL DATA
 
The working voltage is 220V of switch controller
The Switch mechanical life(N-R-N circulation) is 5000 times
The switch has operating handle, as emergency manual operating switch using. (using in the condition ofblackout)
It Has three steady working states:


FEATURES & FUNCTIONS
 
Display Description
This dual-power transfer switch has "Manual" function for manual switching between the normal power and reserve power, and "Automatic" function for automatic switching between the two power supplies, as well as word display such as "Automatic", "Manual", "Normal power undervoltage", "Normal power overvoltage", "Normal power on", "Normal power tripping", Reserve power undervoltage", "Reserve power overvoltage", "Reserve power on", "Reserve power tripping".
?  When the normal and reserve power supplies supply power simultaneously, if the normal power voltage is higher than 115% or    lower than 85% of the rated voltage, the dual-power switching system will judge it as fault and transfer to the reserve power supply automatically, and display "Normal power overvoltage" or "Normal power undervoltage".
? When the normal and reserve power supplies supply power simultaneously, if the normal power voltage is higher than 115% or lower than 85% of the rated voltage, the dual-power switching system will judge it as fault and transfer to the normal power supply automatically, and display "Reserve power overvoltage" or "Normal power undervoltage".
? In normal power supply state, the circuit breaker trips due to voerload or short circuit, it will display "Normal power tripping".
?  In reserve power supply state, the circuit breaker trips due to voerload or short circuit, it will display "Reserve power tripping".
 
Key operation description
 
In manual state:
 ?  Press the normal power key until hearing the beep sound, to switch to the normal power supply. 
?  Press the reserve power key until hearing the beep sound, to switch to the reserve power supply.
In automatic state:
?When both the normal and reserve power supplies are regular,the dual-power system will transfer to normal power supply automatically, and display automatic normal power on.
? When the normal power supply is failed, the dual-power system will transfer to reserve power supply automatically, and display normal power undervoltage and automatic reserve power on.
?When the reserve power supply is failed, the dual-power system will transfer to normal power supply automatically, and display  reserve power undervoltage and automatic normal

power on. 
? Normal power key and reserve power key are ineffective at this monent. 
? Press the double-breaking key until hearing the beep sound, to break the two circuits. 
?  Press the double-breaking key until hearing the beep sound, to break the two circuits. Press the automatic key until hearing the beep sound, to turn the system into manual operation.
 
Control functions of the intelligent automatic controller
 
?  Mode of auto-switch-in auto-restoring is suitable for power grid-power grid. The intelligent automatic controller carries out automatic switching between the two circuits of power supply(i.e. normal and reserve power supplies), power supplied by the normal power supply under normal condition, and transfer to the reserve power supply automatically after the preset time delay (adjustable) once the normal power is failed or is abnormal (any one group of voltage occurs overvoltage,undervoltage, no-voltage or open-phase), and return to the normal power supply automatically after the preset time delay (adjustable) when the normal power supply recovers.
 
? Mode of auto-switch-in without auto-restoring is suitable for power grid-power grid. The automatic controller with mode of auto-switch-in without auto-restoring carries out automatic switching between the two circuits of power supply (i.e. normal and reserve power supplies). It transfers to the other normally operated power supply after the preset time delay when one power supply is abnormal (any one group of voltage occurs overvoltage, undervoltage or open-phase), and will not restore automatically when the abnormal one recovers.
 
 
?Power grid-generator, when it is used in the power gridgenerating system, the automatic controller catrries out switching between the power grid and generator. When teh power grid voltage is lower than 85% of the rated voltage, the controller sends out power generation command (output by one group of NO NC contacts). when teh generating voltage reaches 85% of the rated voltage. it cuts off the load circuit from the power grid first, then put through the generating power supply after time delay. When the power grid recovers normal (reaches 85% above of the rated voltage), the controller will cut off the loads from the generating power supply and    transfer to the power grid automatically through intelligent logical judgment.
