Diagnostic equipment Medical Imaging Therapy equipment
The mission critical nature of medical devices demands high quality, reliable and safe products. Our goal is to
consistently deliver products that meet this criteria and to help our Customers to meet this goal. Medical Power
supplies are crucial part of the equipment, usually you can have open frame, enclosed, fanless, and configurable
models as well as wall-mount adapters and DC-DC modules. Often the backup battery is part of the Power
Supply to guarantee the continuity of the operation also in case of interruption of main energy.
