The core function of an ATS is to automatically switch the power supply from the main source to a backup source when the main power fails, and then switch back to the main power once it is restored. The typical working process of an ATS is as follows: 1. Normal Condition When the main power…
Let’s walk through a few key technical parameters that come into play when selecting an ATS—these directly affect whether the equipment can match up with the system and whether the transfer goes smoothly. 1. Voltage Rating The rated voltage of the ATS needs to match the grid voltage. Common setups include low-voltage (220/380V) and high-voltage…
An automatic transfer switch (ATS) is, simply put, a specialized electrical device designed for switching between dual power sources. Under normal operating conditions, it draws power from the primary source while simultaneously monitoring the circuit status in real time. Should the primary power supply fail—whether due to an outage, voltage instability, or other supply issues—the…
