Power Supplies
An important part in HVAC systems are power supplies. They supply power to other control parts in HVAC systems such as safety switches, control boards and thermostats. They are fundamental in providing the correct current and voltage to control parts by converting electrical power from high voltage to a lower voltage....Read more
Their role is important because voltage fluctuations can damage other electronics or cause the system to become unstable. By supporting other parts in the system, power supplies enable the HVAC system to regulate and monitor pressure, airflow, and temperature. Being able to properly monitor these aspects of a building’s system can help building owners and facility managers to identify issues before the system fails.
Troubleshooting power supplies would include using a multimeter to check the incoming and outgoing voltage. Looking for physical damage and erosion are visible signs of burning or corrosion. Checking load conditions by disconnecting control boards, thermostats, or other parts can also help pinpoint where in the system the issue is coming from.
Building owners and property managers should inspect HVAC power supplies at least twice a year. Often this is done in the fall and spring during regularly scheduled maintenance.
