DUAL POWER AUTOMATIC TRANSFER SWITCH: This 100A automatic transfer switch is designed for power systems such as generators and non photovoltaic backup power sources, with millisecond level power conversion function. When the main power supply fails, it can quickly switch to the backup power supply within 0.05 seconds to ensure the continuity, reliability, and safety of the power supply. When the public power supply returns to normal, it will automatically switch from the backup power supply to the main power supply. Simultaneously supporting manual operation, making power switching more flexible and convenient.
VISUAL DISTRIBUTION BOX SHELL: This transfer switch comes with a distribution box shell, which is made of high-quality steel material, a visual transparent flip cover, C45 guide rails, and wiring terminals, making it safe and durable. Under the protection of the anti touch shell of the power supply, the ATS conversion switch can be clearly viewed or operated, providing safety assurance for personnel and equipment, making your use safer and more reassuring.
110V OVERVOLTAGE AND UNDERVOLTAGE PROTECTION: The 110V automatic transfer switch is suitable for 50/60Hz dual power grids, with a maximum load current of 100A. 110V/50Hz undervoltage value: 85V, recovery value: 95V; overvoltage value: 145V, recovery value: 130V (± 5V). The automatic transfer switch has dual protection functions for overvoltage and undervoltage, effectively reducing the risk of electrical faults, thereby improving the stability, safety, and equipment life of the electrical system.
WIDELY APPLICABLE: This dual power transfer switch ensures stable power supply and is suitable for power systems and equipment that require stable power input and dual power supply protection; ATS is an excellent equipment used in homes, hospitals, low-temperature cold storage, data centers, and emergency systems. It can quickly switch to the backup power supply within 0.05ms in the event of a main power outage to ensure safe and reliable power supply.
QUALITY ASSURANCE: The generator transfer switch is made of high-quality materials with guaranteed quality. The product offers a 30 day no reason return and a 3-year warranty to ensure you have a worry free shopping experience.
