These include a number of protections including over-voltage, under-voltage, over-load and short circuit, and thermal-shutdown
Powerbox, one of Europe’s largest power supply companies, and for more than four decades a leading force in optimizing power solutions for demanding applications, announces the introduction of three new series of 15W, 20W and 30W board mount DC/DC converters for demanding medical applications, totaling 105 models. The PMM15, PMM20 and PMM30 are certified to the 3rd Edition of the IEC/EN/ANSI/AAMI ES 60601-1 medical safety standard and rated for the highest levels of patient protection – two means of patient protection (2x MOPP).
Many countries such as China or those in South America are bringing healthcare to populations based in mountainous regions, and it is very common in those countries for healthcare centers and hospitals to be located at altitudes higher than 3,000 meters. Medical equipment must be designed to guarantee the highest level of safety up to 5,000 meters. Powerbox’s PMM15, PMM20 and PMM30 have been designed for this and they also comply with the Chinese Safety Standard GB 4943.1-2011 requirement for operation at altitude.
Supplied in a non-conductive black plastic housing and potted with a UL94-V0 silicon compound, the PMM15 and PMM20 are sized at 40.6 x 25.4 x 10.2 mm (1.6 x 1 x 0.4 inch) and weigh 24 grams. The PMM30 is available in a 50.8 x 25.4 x 10.2 mm (2.0 x 1.0 x 0.4 inch) housing and weighs 32 grams.
Without using external components, the PMM15, PMM20 and PMM30 meet EMI levels as specified by EN55011, EN55032 and FCC Part 18, Class A.
According to the MIL-HDBK-217F, at full load and +25 degrees C, the PMM15, PMM20 have an MTBF of 2 million hours, and the PMM30 of 1.1 million hours.
An optional remote control pin (P) for positive logic and (N) for negative logic is available to externally control ON/OFF. All single output voltage modules can be externally adjusted up and down by adding a resistor bridge connected to the trimming pin.
The PMM15, PMM20 and PMM30 are suitable for a very large range of medical applications such as home healthcare auxiliary equipment, ultrasound, assisted ventilation, infusion pumps, dental chair and supervisory systems and many others. In industrial applications, the 5,000VAC reinforced isolation figure makes the PMM an ideal solution to add, at low cost, an IGBT drive channel to any industrial power supply, meeting the safety requirement required by such applications.
- Clearance and creepage distance of 8mm.
- Leakage current of 2µA.
- 5,000VAC isolation voltage.
- No load to full load of +/-0.2% on single output and +/-0.5% on dual output.
- Efficiency of 90%
- Ambient temperature of -40 to +105 degrees C. In cases of excess of heat, an internal over-temperature protection is set at +115 degrees C.
The PMM family includes 6 series, 3W PMM03 ; 6W PMM06 ; 10W PMM10 ; 15W PMM15 ; 20W PMM20 and 30W PMM30. The PMM15, PMM20 and PMM30 wide input (2:1) units are available in three input voltage ranges, 9-18V, 18-36V, 36-75V, and the ultra-wide input (4:1) versions in two input voltage, 9-36V and 18-75V. All models are fully regulated with a complete range of output voltages comprising 5V, 12V, 15V, 24V, +/-5V, +/-12V and +/-15V.
The power converters are covered by a five year warranty.
All products conform to the European directive RoHS, REACH and are CE marked.
