Detailed Product Description Automatic Transfer Switch YES1-63N (6A~63A) 3P/4P Connection: Utility - Utility Function: over load protection;under voltage,lost phase protection This series automatic transfer switch which is suitable for using in double power supply system with rated voltage below 415V (660V), rated frequency 50Hz/60Hz,rated working current 63A and below, which is used in hospital, shop, bank, high building, coal mine, telecommunication, iron mine,superhighway, airport,etc. important situation where disallow power supply failure. Service Range This series automatic transfer switch is designed and developed by our company. It complies with GB/T14048.6 standard. All of parts, components are well selected, the finished products are under continuous 168 hours drying power-on running, and finally pass our serious checkout then leave our factory, thus, greatly ensure the reliability and safety. Service Condition: Not over altitude 2000m. Ambient temperature : -10~+40° CPollution protection: Class IIIThere must be not any explosive medium and no gas that would corrode metal or any con-ducting dust that would destroy the insulation. Atmospheric condition: the air relative humidity should not be more than 50% at+40°C, no higher relative humidity under lower temperature, the average humidity of the wettest month should not be more than +25, the average max. relative humidity of this month should not be more than 90%; WORK PRINCIPLE When common source is normal, the functional key is at position "auto", reserve breaker is open and common breaker is close to protect common source for connecting with load, the common power voltage indicator is light. When the common source failures (the voltage is lower than 60% of rated voltage), the common source will transfer to reserve source automatically, the reserved source voltage indicator is ON, the reserved source working indicator is ON. After removing the failure of the common source, this switch will transfer to the common source automatically again. Main characteristicAutomatic controller exam the voltage of two circuit at the same time. When power voltage higher than rated value 110%, considering over voltage, while lower than rated value 60%~80%, considering under voltage. Computer judges and deal with the exam result, then sent orders such as switch on, switch off, generate, uninstall or alarm. The above exam result showed on the control board and also can be connect with computer supply for user to exam reason. Intelligent controller has three types: automatic switch and restore suits for power network -power network and power network -generator, automatic switch without restore suits for power network-power network.=Self-transfer and self-recovery (R) suits for power network -power network Making is consider as common power acquiescently, when common power is abnormal,it will transfer to zero position after three seconds, and through delayer transfers to reserve power (R) automatically. The delay time can be set 0~30 seconds. Self-transfer and non-self recovery suits for power network -power network Controller exams and transfers common power (N) and reserve power (R) in the two supplying powers. Consider common power as initial state, when common power (N) is abnormal, it will transfer to zero position after three seconds, and through delayer transfers to reserve power (R) automatically. But it won't restore after common power (N) is normal.
