Which device can provide a temporary power outage protection for HVAC equipment?

A battery backup system is designed specifically to provide temporary power during a power outage. It typically consists of batteries that store electricity and can supply power to HVAC equipment when the main electrical source is interrupted. This feature is especially important for systems that require continuous operation to maintain climate control, such as heating or cooling systems that protect sensitive environments.

In contrast, while voltage stabilizers, circuit breakers, and surge protectors serve important functions in protecting HVAC equipment, they do not provide the same level of power outage protection. Voltage stabilizers help maintain consistent voltage to avoid damage from voltage fluctuations, circuit breakers are designed to interrupt the electrical flow in case of overloads or faults, and surge protectors safeguard against voltage spikes. None of these devices can supply power when utility electricity is unavailable, making the battery backup system the correct choice for temporary power outage protection.
