Advertorials Powerbox announces 105 models of DC/DC
converters featuring 2xMOPP medical approvals • Reinforced isolation: 5,000VAC with two means of patient protection (2xMOPP) • Low leakage current of 2µA, low standby power and no minimum load required • Wide-input (2:1) and Ultra wide input (4:1) voltage ranges covering from 9V to 75V • Operating altitude up to 5,000 meters
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 - 2xMOPP. With a clearance and creepage distance of 8mm, a typical leakage current of 2µA and a 5,000VAC isolation voltage, the modules ensure operator and patient safety and protection in medical applications. For optimized efficiency and flexibility, all models are available in wide input (2:1) and ultra-wide input (4:1) versions covering from 9V to 75V input voltage and providing seven different output voltages from 5V to +/-15V. The power converters are covered by a five year warranty.
In medical equipment, safety is an absolute must and as specified in the IEC/EN/ANSI/AAMI ES 60601-1 safety standard, the PMM15, PMM20 and PMM30 have an input to output isolation voltage of 5,000VAC. They integrate a reinforced insulation with two means of patient protection (2x MOPP), have a typical leakage current of 2µA and a clearance and creepage distance of 8mm.
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.
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.
No minimum load is required and tight regulation from no load to full load of +/-0.2% on single output, and +/-0.5% on dual output is provided.
Designed around an optimized topology, the PMM15, PMM20 and PMM30 have an efficiency up 90% and can be operated within an ambient temperature of -40 to +105 degrees C. In the case of natural convection a derating may apply. In cases of excess of heat, an internal over-temperature protection is set at +115 degrees C case.
The PMM15, PMM20 and PMM30 include a number of protections including over-voltage, under-voltage, over-load and short circuit, and thermal-shutdown.
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.
The PMM family includes 6 series, 3W PMM03 ; 6W PMM06 ; 10W PMM10 ; 15W PMM15 ; 20W PMM20 and 30W PMM30.
All products conform to the European directive RoHS, REACH and are CE marked.

Copper busbar delivers high levels of efficiency
for panel builders Rittal has unveiled the new Ri4Power; a streamlined copper busbar that has been designed around the new VX25 enclosure. According to the company, it delivers greater levels of efficiency for panel builders and switchgear manufacturers across electrical power distribution in industrial environments. It also offers other advantages, such as higher current ratings and easier monitoring and maintenance. Solutions based on this system have been tested and certified to IEC 61439.
Automation (including electrical drives and switchgear) is a fastest-growing segment of the UK electrical and electronics industry.
This is being driven by both a boom in mechanical and plant engineering, and by the deployment of more and increasingly powerful drive technologies.
Switchgear for electrical power distribution and motor control centres therefore has to evolve to meet what amounts to ever higher demands, including higher current ratings in conjunction with compact dimensions. Rittal’s new Ri4Power, based on its VX25 enclosure, meets all these challenges.
Busbar design means less copper In contrast to its predecessor, the new copper busbars have a smaller cross-section, which cuts costs. In addition, its streamlined dimensions enable a higher current allowing a higher rated current of up to 6,300A, with short circuit protection up to 100kA for one second. Flat copper bars are used for the various busbar configurations, with a maximum of four bars per phase.
The busbar supports have been redesigned so they suit both 600 and 800mm deep enclosures, and they can be attached either to the left or right side.
