Power to low-voltage medical equipment should be supplied from what type of source?

Power to low-voltage medical equipment should be supplied from an individual portable isolation transformer to ensure the safety and functionality of the equipment. An isolation transformer is essential in medical settings because it provides electrical isolation from the power source, which helps to protect patients and staff from electrical shock and equipment malfunction. These transformers reduce the risk of current leakage and potential electrical hazards, which is crucial in a medical environment where patients may be connected to monitoring equipment or have invasive devices.

An individual portable isolation transformer is particularly advantageous because it can be moved as needed, providing flexibility while maintaining the safety standards required in medical applications. By isolating the equipment from the direct electrical supply, it minimizes the chances of short circuits and other electrical issues that could endanger lives.

In contrast, other options like a standard outlet do not offer the necessary isolation and safety features required for medical equipment. Central power supplies might not provide the individualized protection needed for patient care. Battery backup systems are valuable for ensuring power continuity during outages, but they do not offer the isolation that protects both equipment and patients from potential electrical issues. Thus, an individual portable isolation transformer is the most compliant choice for supplying power to low-voltage medical equipment.
