คำถามที่พบบ่อย

Q1: What is the difference between ATS and MTS?

ATS automatically switches power sources without manual operation, while MTS requires manual switching.

Q2: Why do I need an Automatic Transfer Switch?

The automatic transfer switch can automatically and quickly switch to the backup power supply, in case of a failure of the main power supply, preventing equipment shutdown, business interruption or loss of stored items due to power outage. It is suitable for application scenarios where power continuity is required. At the same time, ATS can prevent the backup generator from sending power back to the public grid, reducing electrical risks and providing a safer maintenance environment for power maintenance personnel.

Q3: Can YRO provide OEM ATS manufacturing?

Yes. YRO supports OEM and ODM customization for electrical parameters, enclosure design, and branding.

Q4: Does YRO provide aอัตโนมัติ changeover switches with timer control function?

Yes.

YRO provides WiFi changeover switch solutions with smart control functions to meet different application requirements, including models with timer control functions.

An ATS with timer control allows users to manage power switching according to preset schedules, such as scheduled power source transfer or backup power management. This function is suitable for applications that require intelligent power management and automated operation.

Q5: Is emergency power switch wiring complicated?

The wiring process of an emergency power switch mainly depends on the product model, power source configuration, and application scenario.

Generally, an emergency power switch needs to be connected to the main power supply, backup power source, and load terminals according to the wiring diagram. YRO uninterruptible power supply products feature clear terminal markings and installation instructions to help installers complete wiring efficiently.

For different applications, such as generator backup systems, solar power systems, or industrial power systems, customers should select the appropriate ATS model and wiring method according to their electrical design requirements.
