Automatic Transfer Switches

Main uses

RP6E 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 normal power and reserve power but without manual operation.This switch accords with the following terms of national GB/T14048.11 automatic transfer switch stand a red

Operating mechanism should have reliable electric a and mechanical interlocking， in order to  prevent concurrent access to the normal power and reserve power.

When the voltage of detected any phase and all the phases of the normal power interrupt in a scheduled  time.RP6Ewillswithch to connect the load from normal power to reserve power，and when the normal power goes back to normal， it wll automatically connect the load to the normal normal power(with phase failure protection function) .

Technical parameters

♦ The working voltage is220V of switch controller 

♦ The switch mechanical life(N-R-N circulation) is 5000 times

♦ Minimum shift action time 1.54S

♦ The switch has operating handle， as emergency manual operating switch using.

  (using in the condition of blackout)

It has three steady working states：

♦ State1：commonpowerswitchon， standby power off

♦ State2：commonpowerswitchoff， standby power on

♦ State3：commonpoweroff， standby pow

Key operation description

In manual state：

♦ Press the normal power key until hearing the beep sound，to switch to the normal powersupply.

♦  Press the reserve power key until hearing the beep sound，to switch to the reserve powersupply.

In automatic state：

♦  When both the normal and reserve power supplies are regular， the dual-power system wll transfer to normal powersupply automaticaly，and display automatic normal power on.

♦ When both the normal and reserve power supplies are regular， the dual-power system wll transfer to normal powersupply automaticaly， and display automatic normal power on.

♦ When the reserve powersupply is failed， the dual-power system wil transfer to normal powersupply automaticaly， and diplay reserve power undervoltage and automatic normal power on.

♦ 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 automatic operation.

♦ Normal power key and reserve power key are ineffective at this mon ent.

♦ 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
