Low-voltage thermostats normally operate on both AC and DC power, allowing them to be versatile and used in various power supply situations in HVAC systems.
Low-voltage thermostats typically operate on both AC and DC power. Alternating current (AC) is commonly used in most large power distribution systems because it can be transmitted with much smaller power losses compared to direct current (DC), especially over long distances. AC power also allows for easier voltage transformations, which is essential for efficient power distribution and safety.
In the context of a low-voltage thermostat, which operates at a safer, reduced voltage than the main AC power supply, it can be designed to work with either AC or DC, providing versatility in power supply options. These devices are often used in residential and commercial heating, ventilation, and air conditioning (HVAC) systems.
