Medical Power Supplies

The Importance of Medical-Grade Power Supplies

Medical applications are typically high-risk and require electronic equipment with superior reliability and compliance with safety standards. The last thing anyone wants when performing medical procedures is for the power to go out. Astrodyne TDI's medical power supplies meet the IEC 60601-1 safety standard and provide continuous power to various medical equipment.

Different Medical Power Supply Requirements

Medical equipment power supplies fall into different categories depending on their application and requirements:

• MOOP: Means of Operator Protection (MOOP) power supplies are for devices that don't come into contact with a patient. These devices are subject to ITE Laboratory Environment Compliance standards 60950-1 and 62368-1.
• MOPP: Means of Patient Protection (MOPP) power supplies are for devices that directly involve or contact patients. As these devices could put a patient at risk, they must abide by stricter standards, provide insulation to protect patients from electric shock and stay within the current leakage limit value.
• Type B: Type B power supplies cover medical devices with lighting systems but have no direct physical contact with patients.
• Type CF: Type CF medical power supplies are for devices that come into contact with a patient's heart, such as defibrillators. If they fail to operate properly, this particular type of power supply may cause a patient to be severely injured.

Electromagnetic interference and immunity standards are also important for medical device power supplies. To prevent patient injury, medical power supplies must avoid disruption caused by radio or electromagnetic interference.

What to Look for in Medical-Grade Power Supplies

Medical-grade power supplies may appear similar to commercial-grade devices, but they have features and functions that meet the IEC 60601-1 standards. When choosing a medical-grade power supply for your specific needs, here are some things to look for:

• Output voltage and current
• Power rating
• Form factor and mounting
• Electrical connection
• Thermal management
• Environmental factors
• Safety standards
• Horizontal standards
• Dual line fusing

These factors are essential to the overall functionality of the medical power supply. Learn more about these features and how they contribute to Astrodyne TDI's power supply solutions.

Safety Requirements for Medical Power Supplies

Due to the lifesaving nature of medical devices, related power supplies are some of the most stringently designed and manufactured electrical components across all industries. Medical device manufacturers must meet the IEC's 60601-1 safety standards, which outline a number of design issues unique to medical applications.

In general:

• Medical equipment must have reinforced or double insulation to meet low leakage requirements.
• Components — AC input, DC output and power supply — must be reliably isolated to reduce the risk of shock.
• There must be further isolation around other electrical components like conductors.
• Medical devices must undergo thorough design processes and have a longer life cycle.
• Medical facilities must have quick and reliable support from their vendors and manufacturers.
