Features 【Flame Retardant Material】: This dual power automatic transfer switch is made of high quality flame retardant plastic material, good insulation performance, good flame retardant effect, high temperature resistance, anti-aging, safe and reliable. 【Silver Contacts】: The automatic transfer switch adopts silver contacts both dynamic and static, which has good electrical conductivity and long service life. Both dynamic and static use silver contacts, which greatly improves the conductivity and service life of the product. 【Automatic Adjustment】: Dual power automatic transfer switch, suitable for switching to backup power when power is off, and switching to main power when power is on. When the power supply is abnormal, the backup power supply of the dual power supply automatic transfer switch will work immediately to ensure normal power supply; when there is power, it will switch to the main power supply. 【Signal Light】: The dual-power automatic transfer switch has a built-in standby opening signal output port, which can be connected to an external signal light, which is convenient for observation outside the cabinet. 【Continuity of Power Supply】: When the common power supply is abnormal, the backup power supply will work immediately to ensure the continuity, reliability and safety of power supply.
