Powerbox onboard DC / DC converter new product launch

Powerbox is one of the largest power companies in Europe and has been a leader in demanding applications and optimized power solutions for more than 40 years, announcing the launch of three new series of 15W, 20W and 30W onboard DC/DC converters. For demanding medical applications, a total of 105 models. The PMM15, PMM20 and PMM30 are certified to the third edition of the IEC/EN/ANSI/AAMI ES 60601-1 medical safety standard and are rated as the highest level of patient protection - 2xMOPP. The module has a clearance and creepage distance of 8 mm, a typical leakage current of 2 μA, and an isolation voltage of 5000 VAC, ensuring the safety and protection of operators and patients in medical applications. To optimize efficiency and flexibility, all models are available in wide input (2:1) and ultra-wide input (4:1) versions, covering input voltages from 9V to 75V and providing seven different outputs from 5V to +/-15V Voltage. The power converter is warranted for five years.

In medical equipment, safety is absolutely necessary, and the input and output isolation voltages of the PMM15, PMM20, and PMM30 are 5000Vac according to the IEC/EN/ANSI/AAMI ES 60601-1 safety standard. They integrate reinforced insulation and two patient protection methods (2x MOPP) with a typical leakage current of 2 microamps and a clearance and creepage distance of 8 mm.

Many countries, such as China or South America, are bringing health care to the mountain population, where medical centers and hospitals are located more than 3,000 meters above sea level. Medical equipment must be designed to ensure a maximum safety level of 5,000 meters. Powerbox's PMM15, PMM20 and PMM30 are designed for this purpose. They also meet the requirements of the Chinese safety standard GB 4943.1-2011 for working at heights.

The PMM15, PMM20, and PMM30 wide input (2:1) units have three input voltage ranges: 9-18V, 18-36V, 36-75V, and two input voltages (9-36V and 18-75V) for ultra-wide inputs (4 :1) Version. All models feature full range regulation of output voltages including 5V, 12V, 15V, 24V, +/-5V, +/-12V and +/-15V.

No minimum load is required, with a strict regulation of +/-0.2% from no load to full load on a single output and +/-0.5% on a dual output.

The PMM15, PMM20, and PMM30 are designed around an optimized topology with efficiencies as high as 90% and operate at ambient temperatures from -40 to +105 degrees Celsius. In the case of natural convection, derating can be used. In the event of overheating, the internal overtemperature protection is set to +115 degrees Celsius.

PMM 15, PMM 20 and PMM 30 include a number of protection devices including overvoltage, undervoltage, overload and short circuit, and thermal shutdown.

The MM15 and PMM20 measures 40.6 x 25.4 x 10.2 mm (1.6 x 1 x 0.4 in) and weigh 24 grams in a non-conductive black plastic case and are packaged with UL94-V0 silicon compound. The PMM30 has a 50.8 x 25.4 x 10.2 mm (2.0 x 1.0 x 0.4 inch) housing and weighs 32 grams.

The PMM15, PMM20 and PMM30 comply with the EMI levels specified in EN55011, EN55032 and FCC Part 18, Class A, without the use of external components.

According to MIL-HDBK-217F, the average trouble-free working time of PMM15 and PMM20 is 2 million hours at full load and +25 degrees Celsius, and the average trouble-free working time of PMM30 is 1.1 million hours.

Optional remote control pins (P) for positive logic and (N) for negative logic for external control on/off. All single output voltage modules can be adjusted up and down externally by adding a resistor bridge connected to the trim pin.

The PMM15, PMM20 and PMM30 are suitable for a wide range of medical applications such as home medical aids, ultrasound, assisted ventilation, infusion pumps, dental chairs and monitoring systems. In industrial applications, the 5000Vac reinforced isolated digital makes PMM an ideal solution to add an IGBT drive channel to any industrial power supply at low cost to meet the safety requirements required for such applications.

The PMM series consists of 6 series, 3W PMM03; 6W PMM06; 10W PMM10; 15W PMM15; 20W PMM20 and 30W PMM30.

All products comply with the European Directives RoHS, REACH and CE Mark.
