Low Noise AC-DC Converters Power Medical Machinery

Even more so than with other machines, downtime in hospitals and other medical facilities is simply not an option. From surgical dialysis and testing equipment to patient monitoring and imaging machines, so many important medical machines need reliable power. 

But picking out a power supply that’s suitable for patient contact isn’t easy—they have to meet strict safety requirements. 

Our new series of linear medical AC-DC converters for medical applications meets these requirements, making it a good choice for such a wide range of machines. These power supplies offer many technical advantages for reliable operation where they’re needed most. 

Meets medical standards. It's not often you find a power supply that both meets medical standards and has low noise. Our new MHIA series of AC-DC converters for medical applications has a low noise of 1.0 mV RMS typical—much lower than your standard medical power supply.

Available with 5 to 250 Vdc output and either a PC mount or chassis mount with screw terminals, this series comes with an encapsulated package for rugged environments. These AC-DC converters provide 4000 Vac reinforced insulation, short circuit protection and 2 Means of Patient Protection (MOPP). In addition, this series meets EMI and EMC standards, as well as IEC 60601-1 Third Edition.

The MHIA series delivers a 2µA patient leakage current, CE certification and a regulation line and load from 0.02 to 0.2%. This series also has very low RMS output noise, an optional wide operating temperature range and available international input voltages including dual and switchable. 

Applications. These diverse power supplies are used in a variety of machines in different sectors of the medical industry. Some examples include: 

  • Surgical: Dialysis equipment, anesthesia delivery, surgical devices 
  • Patient Monitoring: Infusion pump, pulse oximeter, electrocardiograph
  • Imaging: Ultrasound, CT/MRI/X-Rays
  • Laboratory: Sterilizer, mass analysis, lab automation 
  • Diagnostics: Clinical chemistry test, microbiology test
  • Equipment: Dental, Opthomology, therapeutic devices 

9-Watt DC-DC Converters For Tight Spaces

When designing a circuit board, engineers are always looking for their desired wattage in the smallest possible package. Choosing the smallest possible power supply allows for seamless insertion into any circuit board without taking up too much space.

These units can be hard to come by, since power supplies with higher wattages are typically bigger. Our compact, 9-watt SWB9 series of DC-DC converters can help simplify your board layout.

SWB9

Technical features. This model comes in a miniature single inline package (SIP) of 0.86” x 0.36” x 0.44” with 89 percent power supply efficiency and a 4:1 ultra wide input range. The SWB9 product line features an input/output isolation up to 1600 Vdc, continuous short circuit protection and output current up to 2000 mA. This series is also RoHS-compliant to EU directive 2011/65/EU and meets all UL60950-1, EN60950-1 and IEC60950-1 safety standards.

SWB9 comes with either a plastic or metal case. The metal case helps the power supply withstand high operating temperature ranges up to 100°C. Also optional is an extra pin that attaches to the case for grounding and shielding.

This DC-DC converter is ideal for a wide range of applications including:

  • Wireless networks
  • Telecommunications
  • Data acquisition
  • Industrial control systems
  • Distributed power architectures
  • Semiconductor equipment
