ASQ1-100 ~ 250NA end of the dual power transfer switch 

 ■ Product Overview 
 □ ASQ1-250NA Series Intelligent dual power switch applies AC 50/60Hz, rated voltage below 400V, rated current of 250A dual power supply system, to achieve a common power supply (N) (R) and standby power automatically switch (can also be set to manual switching), to supply the user to achieve unattended substation. This product is suitable for the important place of the special class, the class I electric power system, high-rise buildings, residential quarters, military installations, hospitals, airports, terminals, shopping malls, communications, fire protection, metallurgy, chemicals, textiles, petroleum, coal, etc. do not allow the power outage. 
 □ ASQ1-250NA Series Intelligent dual power transfer switch has three optional ways of working: automatic recovery, since a vote of no automatic recovery, and backup each other; use in the operating voltage of AC380V Motor loads or including motor, resistive load and 30% incandescent load, mixed load. 
 □ switch driver using SCM structure is simple, smooth and reliable switching, no noise, the impact is small. 
 □ switch with load automatically switch to an emergency can be handle manually switch; interlocks between manual and automatic plus manual operation to ensure that can not be run automatically work.
