Feature:1. RELIABLE POWER SWITCHING: The dual power automatic transfer switch ensures seamless switching between the primary and backup power sources, guaranteeing uninterrupted power supply in case of a failure or outage.2. FAST TRANSFER SPEED: With a switching time of less than 50 milliseconds, this automatic transfer switch swiftly transitions from the main power source to the backup power source, minimizing downtime and keeping power systems operational.3. WIDE COMPATIBILITY: Designed to work with AC systems operating at 50 to 60Hz, this transfer switch is compatible with various power grids and is suitable for different applications and industries.4. HUMIDITY CONTROL: When the ambient temperature is +40, the relative humidity at the installation site should not exceed 50%. The relative humidity can be higher at lower temperatures. For example, when the average lowest temperature in the most humid month is +20, the maximum average relative humidity for that month can arrive 90%. Appropriate measures should be taken to prevent condensation caused by temperature changes.5. EASY INSTALLATION AND FLEXIBILITY: The transfer switch can be mounted vertically or horizontally inside cabinets, offering flexibility in installation.Specification:Item Type: Dual Power Automatic Transfer SwitchMaterial: PC Flame RetardantRated Current In: 25AInsulation Voltage Ui: 690VACGrade: PCFrequency: 50 60Hz Standard: For IEC60947 6Rated Short Circuit Current Limit (RT16 00 63A): 50KA.Package List:1 xSwitch
