Zgq5-1004P 220V 100A Power Transfer Switch, Anti-Aging, Safe, And Reliable Dual Power Automatic Transfer Switch,ZGQ5 100/4P 220V 100A Power Transfer Switch,Anti-aging, Safe and Reliable Specification: Item Type: Dual Power Automatic Transfer Switch Material: Plastic Working Frequency: 50 60HZ Rated Current: 100A Rated Voltage: AC110 230V Working Voltage: AC220V Operation Mode: Automatic and manual ATS: CB level Conversion Time: =0.05 (S) Number of Poles: 4P How to Use: 1. Place the automatic transfer switch of the dual power supply on the debugging platform, and connect the corresponding power line according to the correct phase sequence. The phase line and the neutral line are connected in position, and the wrong connection is not allowed. 3. When debugging the three pole switch, the common and spare neutral wires should be connected to the neutral terminal (NN and RN) respectively. 3. Set the dual power supply automatic transfer switch to work in the self turning and self resetting mode. If the voltage of the two power supplies is normal, the switch should be placed in the common power supply position, and the common power supply is closed. 4. Set the common power supply NA, NB, NC, NN for any phase loss, the dual power supply should be automatically converted to the backup power supply, if the common power supply returns to normal, it should be converted back to the common power supply 5. Adjust the voltage of any phase of the common power supply to the predetermined undervoltage voltage value, and the dual power supply should automatically switch to the standby power supply. When the normal power supply returns to normal, the switch should return to the normal power supply Package List: 1 x Dual Power Automatic Transfer Switch 1 x User Manual Product Features [Silver Contacts]The use of silver contacts can greatly improve the conductivity and service life of the product [Easy to Use]Built?in regular standby opening signal output port, which can be connected with signal indicator light, which is convenient for observation outside the cabinet [Made of High Quality Materials]Using high?quality flame?retardant plastic material, good insulation, high temperature resistance, anti?aging, safe and reliable [Reliable and Practical]When the normal power supply is abnormal, the backup power supply will work immediately to ensure the continuity, reliability and safety of the power supply [Wide Applicability]Suitable for switching to the backup power supply when the power is cut off, and switching to the main power supply when the power comes in Shipping: Shipping is complimentary within the lower 48 US States.
