Characteristics
1.The operation mechanism has stable dowel between electrics and mechanics to protect the
normal power supply and spare power supply connected at same time.
2.Within preset time, under the working status and the situation of outage or other faults
occurred on any term of normal power supply being on inspected and / or all the phase
voltage, the switch will automatically switch the load from the normal power supply to the
spare power supply and connect the load automatically back to the normal power supply
according the set time after the normal power supply return to the normalcy, this product
has the characteristics of open phase protection and overload protection.
3.The switch could manually set the double phase of normal power supply and spare power
supply at ZERO POSITION which is applicable for extinguishing and protection needs.
The double phase "ZEOR POSITION" is normal power supply and spare power supply under
the status of switching in.
4.In the case of similar mechanical structure, the product structure could be exchanged with
implementation mechanics like ABB circuit breaker or Schneider breaker (different molded
case circuit breaker and Miniature Circuit Breaker).
Product Introduction
For the demand of the present market, our company has just been developed a new Dual
Power Automatic Switch.
SFZM series Dual Power Automatic Switch is an ideal mechatronic product which is applicable
to the dual power supply system of AC 50/60Hz with rated voltage under 1000V and current
under 630A, achieved the auto-switch between the normal power (N) and spare power (R) (also could be set as the manual
switch), enabled the dual power supply users stay in a permanent power supply environment.
The SFZM series Dual Power Automatic Switch is in accordance with the standards of GB14048.11
and IEC 947-61.
It wildly applies in highrise buildings, residence community, shopping mall, airport, station,
bank, post & telecommunication, hospital, extinguishing and protection, chemical industry,
metallurgy and such place where is not permitted any outage occurred.
