Double power automatic transfer switch high speed 2P millisecond PV circuit controller AC220V type Feature: 1. Fire retardant materials: made of excellent flame retardant plastic materials, have good insulation, high temperature resistant, aging resistant, safe and reliable 2 .Silver contacts improve conductivity: the use of silver contacts in this product can greatly improve the conductivity and service life of the product 3. Miniature and practical: double power automatic switch is a miniature household power switch that mainly serves to test whether the main power source or backup power supply is normal to ensure power supply continuity, reliability and security. This product is specially designed for railway installation, dedicated to PZ30 distribution box 4. Milliseconds switching without interruption: when the normal power supply is abnormal, the emergency power supply works immediately, and the power supply is switched in milliseconds without interruption 5. For multiple places: switch to power supply backup power when there is power failure, and switch to main power source when power recovery. Widely used in various places where continuous power failure is not allowed, such as factories, shopping malls, schools, etc. Specification: Item Type: Double Power Automatic Transfer Switch Material: PC, Silver Voltage Insulation: AC690V Rated voltage: AC400V Coil voltage: 220VAC Level: PC level Specifications: 2P Life: electrical: 2000 times; Mechanical: 5000 times Rated short-circuit current: 50kA Fuse: RT16-00-63A Rated impulse withstand voltage: 8kVObw oacute;d control: Rated control voltage Us: AC220V 85% US-110% UsObw oacute;d Auxiliary: two relays, each relay has two sets contact oacute;w capacity: AC220V50HZ le = 5y Touch time: 50ms Operation transition time: 50ms Return time: 50ms Free time: 50ms Package list oacute;w: 1 x double power automatic transfer switch 1 x user manual Note: 1. Maximum ambient temperature should not exceed 40, the minimum should not be lower than -5, and the average temperature in 24 hours should not be higher than 35. 2. The height of the installation site should not be higher than 2000 meter. 3. When the maximum temperature reaches 40, the relative humidity at the installation site should not exceed 50%; When the temperature is the lowest temperature -5, the relative humidity is higher, for example, if the temperature is 25, the relative humidity is 90%. Special measures must be taken to deal with occasional condensation on product surfaces due to temperature changes. How to use: Mounted on rails for use.
