Frequently Asked Questions (FAQ)
What is a Dual Power Automatic Transfer Switch (ATS)?
A Dual Power Automatic Transfer Switch (ATS) is an electrical device designed to automatically transfer a load supply between two independent power sources (primary and backup power) to ensure continuous operation of critical electrical installations in case of power outages.
What protection functions are built into this ATS?
This dual power automatic transfer switch is equipped with advanced protection capabilities including short circuit protection, overload protection, under-voltage protection, and voltage loss protection. It also features fire protection integration interfaces and output signal switching.
Where is the SAQ3-100 Dual Power Automatic Transfer Switch suitable for use?
It is highly recommended for locations requiring stringent fire safety measures, such as office buildings, commercial shopping malls, banks, train stations, hospitals, high-rise buildings, and public emergency fire lighting circuits.
What is the typical transfer time for this equipment?
The transfer time varies by specification: for models 20A to 250A it is 0.45s; for 400A to 630A it is 0.6s; and for larger industrial specifications from 800A to 1600A, the transition is completed within 1.2s.
What control power supply voltages are supported?
The ATS control power systems support multiple voltage inputs depending on the application context, including DC24V, DC48V, DC110V, and standard AC220V power configurations.
