Features MAIN USE: Dual power automatic transfer switch is to test whether the main power supply or backup power supply is normal to ensure the continuity, reliability, and safety of the power supply. STURDY CONSTRUCTION: PC shell is flame retardant, fire resistant, high temperature resistant, stable and reliable. Silver contacts ensures premium conductivity and long service life. 2 OPERATION MODES: Operated automatically or manually, millisecond switching constant power, compact structure, reliable transmission, easy installation and maintenance. MILLISECOND LEVEL SWITCHING: When the normal power supply encounters an abnormality, the backup power supply immediately starts working, the power transfer switch achieves millisecond switching to ensure continuous, reliable, and safe power supply. WIDE APPLICATION: This dual power automatic transfer switch is suitable for emergency power supply systems with rated 220V AC 50 or 60Hz, widely used in various places that do not allow continuous power outages, such as factories, shopping malls, nurseries, etc. Spec: Item Type: Dual Power Automatic Transfer Switch Mode: NLQ5 100 3P Material: PC Flame Retardant, Silver Insulation Voltage Ui: AC690V 50HZ Rated Voltage Ue: AC400V 50HZ Level: PC level Specification: 3P Rated Control Voltage US: 220VAC 85% to 110% Us Life: Electric: 2000 times; Machinery: 5000 times Rated Short Circuit Current: 50kA Fuse: RT16 00 63A Rated Impulse Withstand Voltage: 8kV Auxiliary Circuit: 2 relays, each with two sets of contact capacity AC220V50HZ le=5y Touch Time: Operation Conversion Time: Return Time: Closing Time: How to Use: Before installation, check the integrity of the ATS, turn the ATS on or off with the handle, check the flexibility of the drive, and check the conditions for the generation and disconnection of loads at each stage of the normal and standby power supply. Package List: 1 x Dual Power Automatic Transfer Switch 1 x Manual Notice: 1. The maximum ambient temperature is not more than 40℃, the minimum is not less than ‑5℃, the average temperature within 24 hours is not higher than 35℃ 2. The installation site should not be higher than 2000m. 3. When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%; When the temperature is ‑5 ℃, the relative humidity is high. For example, when the temperature is 25 ℃, the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with the occasional condensation phenomena on the surface of the product.
