Energy-Efficient 18W Medical Grade Wall-Plug Adapter

UL-approved & compliant with several of the IEC's international standards for medical electronics, the new PMA18A-120PHW adapters are designed for Type BF medical applications, including: CPAP & BiPAP machines, medical imaging equipment, nebulizers, & blood pressure monitors


Phihong, a leading global supplier of OEM power solutions, has released a new energy-efficient 18W medical grade wall-plug adapter designed for use in minimally invasive, bodily floating (Type BF) medical applied parts that have conductive, medium-term, or long-term contact with patients, including: continuous and bi-level positive airway pressure (CPAP and BiPAP) machines, medical imaging equipment, nebulizers, and blood pressure monitors. A limited power source (LPS) with output leakage of <100μA at 264VAC/50Hz, Phihong’s new 18W medical wall-plug adapter is rated for 110 to 240VAC input and 12VDC output.

PH1925 18W Medical AdapterDesignated the PMA18A-120PHW, the new adapter is compliant with UL 60601-1 and several international standards for the safety and effectiveness of medical electrical equipment published by the International Electromechanical Commission (IEC), including: IEC60601-1-2 Ed4 2014, which addresses electromagnetic disturbances, requirements, and tests, and IEC60601-1:2005+A:2012 2xMOPP, which regulates means of patient protection, ensuring a minimum of 4,000VAC isolation, 8mm creepage, and double insulation. The 18W medical grade wall-plug adapter is also compliant with the latest US Department of Energy (DOE) Level VI energy efficiency standards.

“The combination of IEC medical safety approvals and 2xMOPP designation has become a benchmark for the commercialization of medical equipment in many countries. So, the fact that our new 18W adapter is compliant with both, in addition to UL standards, simplifies medical end-product qualifications, saving our OEM customers a significant amount of time and money,” said Keith Hopwood, vice president of marketing for Phihong USA.

The 18W PMA18A-120PHW medical grade wall-plug adapter features built-in over voltage, over-current, short-circuit, over-temperature, and brown-in and brownout protections. Each adapter measures 43.2mm (1.7″) x 82mm (3.23″) x 30mm (1.18″) [L x W x H], and has a 5.5mm x 2.1mm x 10mm fork-and-groove DC plug with an inner (+V) and outer GND(-) plug pin assignment. Allowable operating temperatures for the adapter span 10ºC to +40ºC with up to 95% relative humidity. Pricing in OEM quantities of 100+ starts at $16.20, and samples will be available Q4 2016 at Phihong distributors.
