Feature:1. SAFE AND FLAME RETARDANT: Made of excellent flame retardant PC materials, possess good insulation, high temperature resistant, aging resistant, safe and reliable, using silver contacts can greatly improve the conductivity and service life of the product2. FOR HOUSEHOLD: The ATS has compact structure, reliable transmission, convenient installation and maintenance, specially designed for rail installation, dedicated to PZ30 distribution box3. MINI AND PRACTICAL: Dual power automatic switch is a miniature household power switch, which is mainly used to test whether the main power supply or backup power supply is normal to ensure the continuity, reliability and safety of the power supply4. MILLISECONDS SWITCHING WITHOUT INTERRUPTION: When the normal power supply is abnormal, the backup power supply works immediately, and the power supply is switched in milliseconds without interruption, very useful5. WIDE APPLICABLE: Switch to the backup power supply when there is a power failure, and switch to the main power supply when power recovery. Widely used in various places where continuous power failure is not allowed, like factories, shopping malls, nurseries, etc.Specification:Item Type: Dual Power Automatic Transfer SwitchMaterial: PC, silverRated Current: 100AInsulation Voltage: AC690V 50HzRated Voltage: AC230V 50HzCoil Voltage: 220VACLevel: PC levelSpecifications: 2PLife: Electrical: 2000 Times; Mechanical: 5000 TimesRated Short Circuit Current: 50kAFuse: RT16-00-63ARated Impulse Withstand Voltage: 8kVControl Circuit: Rated Control Voltage Us: AC220V 85% Us-110% UsAuxiliary Circuit: Two Relays, Each Relay Has Two Sets of Contacts Capacity: AC220V50HZ le=5yTouch Time: <50msOperation Transition Time: <50msReturn Time: <50msOff Time: <50ms.Package List:1 x Dual Power Automatic Transfer Switch1 x User ManualNote:1. The maximum ambient temperature should not exceed 40, the minimum should not be lower than 5, and the average temperature within 24 hours should not be higher than 35.2. The altitude of the installation site should not be higher than 2000meter.3. When the maximum temperature reaches 40, the relative humidity of the installation site should not exceed 50%; when the temperature is the lowest temperature of 5, the relative humidity is higher, for example, if the temperature is 25, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes.
