AC/DC External Adapter
Astrodyne TDI offers AC/DC external adapters for medical and industrial applications to help protect and enhance lives. We know that power is important in our daily lives, and a reliable power supply is critical to patients' wellness. This is why we build our power adapters to accommodate the highest standards in health care, as well as automation and instrumentation. Power supply safety and reliability can impact sensitive equipment, and a trusted supplier like Astrodyne TDI can help you meet the most stringent requirements for your application. Let us worry about keeping the power on, so you don't have to.
Medical Grading Standards for AC/DC External Adapters
Medical AC/DC adapters must meet global safety standards for medical supplies, including International Electrotechnical Commission (IEC) 60601-1-2. This standard protects patients and sensitive devices from harmful electric currents by limiting leakage current, also known as "vampire power."
There are two specific safeguards in place — the means of patient protection (MOPP) and the means of operator protection (MOOP). MOPP and MOOP provide protections such as electrical insulation, earth connections, and creepage distances. Contact with the body determines the amount of necessary protection in place.
Medical Protection Classifications
The level of protection necessary depends on three classifications:
- Cardiac floating (CF): This label applies to conductive parts that come into direct contact with the heart or bloodstream and are ungrounded.
- Body floating (BF): This classification of devices has medium- or long-term conductive contact with patients and does not have grounding.
- Body (B): These grounded devices are not typically conductive, and the patient can separate themselves from the device in the event of an electric shock.
Applications of Medical AC/DC Power Adapters
Although the AC/DC power converters are not medical supplies themselves, the power these tools. The IEC 60601-1 has specific allowances for the leakage levels from AC and DC power converters for type CF, BF, and B devices.
Industry professionals have several workaround solutions that help them meet these standards with various degrees of efficacy. You can use a DC/DC converter to create a second isolation stage, but this option often results in a low power level. Another option is to install an isolation transformer. Still, these tools are bulky and often lead to losses in energy efficiency.
The safest, simplest, and most affordable solution is to choose an AC/DC power supply for BF and CF medical devices from a Nationally Recognized Testing Laboratory (NRTL). Medical AC/DC adapters from Astrodyne TDI have a custom design to avoid potential pitfalls, maximize safety and boost efficiency.
