AC 220V Dual Power Automatic Millisecond Transfer Switch Uninterrupted Synchronization Transfer Switch for Domestic Photovoltaic Models (1)

Flame-retardant materials - Made from excellent flame-retardant plastic materials, these switches offer good insulation, high-temperature resistance, aging resistance, and are safe and reliable. Silver contacts - The use of silver contacts in this product greatly improves conductivity and product lifespan. Miniature household power switch - The automatic dual-power switch is a miniature household power switch, primarily used to test whether the main or backup power supply is functioning correctly to ensure continuity, reliability, and safety of the power supply. This product is specifically designed for DIN rail mounting and is intended for use with the PZ30 distribution box. Backup power supply - When the main power supply malfunctions, the backup power supply activates immediately, switching power within milliseconds without interruption. Application - Switches to the backup power supply during a power outage and to the main power supply when power is restored. Widely used in various locations where a continuous power outage is not permitted, such as factories, shopping malls, nurseries, etc. Dual Power Automatic Transfer Switch Miniature Home Power Switch Fast Millisecond Circuit Controller 2P Changing Generator Power Electrical Selectors Switch How to use: Rail mounted for use Specification: Item Type: Dual Power Automatic Transfer Switch Material: PC, Silver Insulation Voltage: AC690V Rated Voltage: 400V AC Coil Voltage: 220VAC Level: PC level Specifications: 2P Lifespan: Electrical: 2000 times; Mechanical: 5,000 times Rated short-circuit current: 50 kA Fuse: RT16-00-63A Rated impulse withstand voltage: 8 kV Control circuit: Rated control voltage Us: AC220V 85% Us-110% Us Auxiliary circuit: Two relays, each relay has two sets of contacts Capacity: AC220V50HZ le=5y Contact time: <50 ms Operating transition time: <50 ms Return time: <50 ms Stop time: <50 ms Package list: 1 x Dual-power automatic transfer switch 1 x User manual Note: 1. The maximum ambient temperature should not exceed 40°C, the minimum temperature should not be less than -5°C, and the average temperature over 24 hours should not exceed 35°C. 2. The altitude of the installation site must not exceed 2000 meters. 3. When the maximum temperature reaches 40°C, the relative humidity of the installation site must not exceed 50%; when the temperature is as low as -5°C, the relative humidity is higher; for example, if the temperature is 25°C, the relative humidity is 90%. Special measures must be taken to address occasional condensation on product surfaces due to temperature changes. https://m.media-amazon.com/images/I/61dA2hg3aVL.jpg
