Small medical devices need small and efficient power supplies. The TRACO TPP15A-D series of open-frame power supplies meet the demanding safety requirements for BF medical equipment such as blood pressure monitors, incubators and ultrasound devices.
The TPP 15-xxxA-D AC/DC power supplies feature a reinforced double I/O isolation system according to medical safety standards IEC/EN/ES60601-1 3rd edition for 2 x MOPP approved for an operating altitude of 5000m. The earth leakage current is below 75 µA which makes the units suitable for BF (body floating) applications. Type BF is generally used for applied parts that have conductive contact with the patient or have medium or long term contact with the patient. Examples of this type of equipment are blood pressure monitors, incubators and ultrasound equipment.
High efficiency versus high isolation voltage is always a challenge for engineers. TPP15A-D has an excellent efficiency of up to 88.5% and offers a high power density in the packaging format only 1.0” x 1.5” (25,4 x 38,1 mm). The full load operating temperature range covers –40°C to +60°C, while the source is able to operate till up to 85°C with 50% load derating.
The units operate in compliance with the medical EMC emission and immunity levels according to the latest standard IEC 60601-1-2 4th edition.
