Medical Power Solutions

XP Power understands the challenges faced by medical device manufacturers due to legislation and market demands. Our products are designed to meet these challenges and provide cost-effective solutions for use in both the hospital and non-hospital environments. Understanding the requirements of our target customers has led to product features that are incorporated for a reason, such as class II approvals for homecare devices, highly efficient convection-cooled designs for low noise patient area devices and defibrillator-proof DC-DC converters for applied part applications.

Medical Power Supplies

Patient Vicinity Legislation

Located in Europe, North America and Asia, our specialist medical technical sales teams offer a clear understanding of the legislation requirements of B, BF and CF classified equipment within the patient vicinity.

If the end equipment is within the patient vicinity, it must meet the isolation and leakage current requirements of IEC60601-1, or its relevant product specific standard, as well as any national deviations such as EN60601-1, UL60601-1 and CSA22.2 No. 601.1 M90. Our AC-DC power supplies provide the primary isolation barrier and the low earth-leakage required to meet these standards.

If the equipment has an applied part, BF or CF classified, an additional isolation barrier is required between the output of the power supply and the applied part and earth. This may be provided by an integral piece of the equipment design such as a non-conductive probe. Where an electrical connection is required we are able to offer suitable solutions for this purpose.

Generally, the patient vicinity is defined as the area where patients normally receive care. It is the space with surfaces likely to come in contact with the patient or an attendant who can touch the patient. It encloses a space within the room 1.83 m (6 ft) beyond the perimeter of the bed (examination table, chair, treatment booth or the like) in its intended location, and extending vertically 2.28 m (7.5 ft) above the floor.

Medical Industry Understanding

EMC Compliance

Our products undergo EMC testing to help us provide as much information as possible during design-in to ensure compliance with IEC60601-1-2. To aid compliance, EMC testing facilities within Europe and North America are available free of charge to customers.

Laboratory Environment Compliance

For equipment used within laboratory environments, compliance with IEC60950 is normally sufficient, involving less stringent isolation and leakage current requirements.

Isolation Barriers

The diagram below illustrates isolation for a typical medical device with an applied part. Two isolation barriers are required to ensure that the applied part is isolated from the ground and meets the patient leakage current limits during normal and single fault conditions. The primary isolation barrier for this type of equipment can be provided by an XP power supply, while the secondary isolation barrier is provided by another system component or XP solution.
