A low-voltage electromagnetic system working on alternating present (AC) at 24 volts, with a frequency of both 50 or 60 Hertz, is often utilized in residential and business heating, air flow, and air con (HVAC) programs, in addition to different management purposes. These parts are regularly accessible for buy at massive house enchancment retailers. As an example, a furnace may make use of such a tool to regulate the fuel valve, opening or closing it based mostly on a sign from the thermostat.
The utilization of those units provides a number of benefits, together with enhanced security because of the low voltage, simplified wiring, and compatibility with a variety of management programs. Their widespread availability and comparatively low value contribute to their prevalence in varied purposes. Traditionally, such units changed greater voltage parts, selling safer and extra environment friendly management mechanisms in automated programs.
