This reduces total downtime to industry-standard figures during which critical systems and appliances are powered down. Some models support remote monitoring access via mobile apps or Wi-Fi, providing real-time updates on generator performance and ATS state, which is novel in the field.
ATS equipment is also rated for its electrical load capacity, which is measured in amperes, as was mentioned earlier. Common residential ATSs with these characteristics range from 50 to 200 amps, while larger commercial systems may handle 400 amps and beyond. These models support a vast array of load configurations, including whole-house applications, and sophisticated prioritization of specific circuits such as critical medical equipment, security systems, and refrigeration, helping ensure uninterrupted service.
Maintaining an ATS is essential for it to work properly. Regular checks, along with testing the ATS under simulated outage conditions, validate that the switch and generator systems are operating correctly. For optimal ATS performance, it is recommended that service schedules be followed and units be tested every quarter at least.
An Automatic Transfer Switch efficiently balances auxiliary power and the grid system, ensuring minimal disruption to everyday and business functions in the event of power outages.
Switching from Utility Power to Backup Power
An automatic transfer switch(ATS) maintains a continuous power supply by automatically switching from utility power to backup power using a backup generator during a utility outage.
