Transfer Switch, AC400V 63A 2 Control Mode Dual Power Transfer Switch Overload   for Hospitals

<ul><li>WORK DETAIL: When a power supply fails only normal phase A voltage and standby phase A voltage are tested, and only voltage loss or phase loss is tested, the switch will automatically connect one or more load circuits from one power supply to another to ensure normal power supply to the load circuit</li><li>DUAL CONTROL MODE: The automated switch has easy  and dependable performance, and the dual power transfer switch not only supports automatic mode but also manual button</li></ul>

<br/><b>Specification:</b><br/>Item Type: Dual Power Automatic Transfer Switch<br>Material: PC Flame Retardant, Brass, PCB, Silver<br>Rated Current: 63A<br>Operating Frequency: 50Hz<br>Rated Voltage: AC400V<br>Coil Voltage: AC220V<br>Display Function: Indicator light display<br> Mode: Automatic, manual<br>ATS : CB <br>Conversion Time: Less than or equal to 2s<br>Usage : AC 33iB<br>Conversion Method: Automatic switching and automatic recovery<br>Working Principle:<br>The power supply  of this series of dual power supply controllers and drive mechanisms  on the A phase and N line input ports of the normal switch or standby switch. In the automatic state of dual power supply, when the common switch voltages of the incoming phase A and N circuits are normal ac190-240v, the common switch will be preferentially closed regardless of whether the voltages of the common power supply B. C and the standby switches a.b.c and N are normal. At the same time, the power LED and the public shutdown LED light up. When the incoming common switch phase A and line N have no voltage, and the incoming standby switch phase A and line N have normal voltage, regardless of whether the voltage of the normal switch B and standby switch C is normal, the dual power supply is switched to standby. The power indicator and the standby close indicator light are on. Manual function, regardless of whether the normal power supply and standby power supply have voltage, can adopt manual  mode. During manual , the manual automatic button should be placed in the manual  position. Rotate the push handle clockwise to the terminal, the standby power supply air switch R is turned on, and the public power supply air switch N is turned on.
