Medical PC Power Supplies with Potential Equalization and International Safety Approvals

November 20, 2019 by Paul Shepard

The newly introduced medical PC power supplies MHG2-5300G-B1 (300 Watt), MHG2-5400G-B1 (400 Watt) and MHG2-5500G-B1 (500 Watt) from Bicker Elektronik provide the reliable ATX ac-dc power supply of mainboards with +3.3V, +5V, +12V, -12V and + 5Vsb. Due to a minimum load of 0 A at all output voltages, the latest generation mainboards with special power saving modes can be supplied.

For international use, the high-performance switching power supplies have an ac wide-range input and comply with the safety standards EN / UL / cUL 60601-1 (Edition 3.1) and CCC.  The well-engineered and energy-efficient circuit design of the new MHG2 series also complies with the 80PLUS® GOLD specification. The high-quality and robust power supplies work in a wide temperature range from -20 to +70 °C.

Potential equalization according to DIN 42801 with PE contact Stäubli S6/15

The new MHG2 power supply series is equipped with a nickel-plated plug of type Stäubli S6/15 for the safe potential equalization according to DIN 42801. With this, the supplied computer system can be kept at the same potential with other components if necessary.

2xMOPP patient protection and international safety approvals

The isolation between input and output is 3000 VAC and thus complies with the safety standard 2xMOPP (Means of Patient Protection). Certified to the strict medical standards EN / UL / cUL 60601-1 and CCC, the new MHG2 PC power supplies can be used almost worldwide in medical computer systems. The AC wide-range input of 90 to 264 VAC (47 ... 63 Hz) with active power factor correction (PFC) enables the supply of a wide variety of AC grids.

Highly efficient and robust 24/7 power supply design

The sophisticated and highly energy efficient switching power supply topology of the new MHG2 series meets the 80PLUS® GOLD specification. The use of high quality components ensures maximum reliability and system availability in 24/7 continuous operation. For example, Japanese brand capacitors of +105°C rating significantly increase the life of the power supply – even at high operating temperatures.

Mechanically, the FR4 board material used has a significantly higher dimensional stability. The through-connection of the printed circuit board ensures long-lasting and stable solder joints.

Pleasantly quiet due to optimized fan control

The fan control has been further optimized in the new MHG2 series, so that the double-ball bearing and temperature-controlled brand fan is particularly quiet and therefore ideal for use in practice and treatment rooms. In addition, the medical PC power supply is equipped with a tacho signal monitoring, which ensures the correct operation of the fan at any time.

Extensive value-added services for medical and laboratory technology

In addition to the three-year device warranty, Bicker Elektronik GmbH guarantees a long-term availability of at least 5 years. In particular, long-running applications in medical and laboratory technology benefit from optimum investment protection and long-term availability. Beside individual design-in advice and first-class service & support from Germany, the engineers at Bicker Elektronik can also implement customer-specific special solutions upon request. The range of services is rounded off by comprehensive laboratory and measuring services for complete customer systems as well as performance profile analyzes for the exact dimensioning of the power supply.

One-Stop Solutions: Tailored Power+Board bundles from a single source

Especially in medical technology, the perfect interaction of all components of a computer system is of decisive, if not even life-sustaining importance. When developing embedded PCs or stand-alone units, developers face the challenge of qualifying core components like mainboard, processor, memory and power supply in many ways.

Even the selection of power supplies and mainboards on the market today is almost unmanageable varied. Here, Bicker Elektronik offers a unique service with its tailor-made Power+Board bundles: System developers receive exactly matching bundles consisting of high-quality power supply solutions and industrial mainboards from well-known manufacturers, as well as suitable processors, memory solutions, expansion cards and mass storage in industrial quality and fixed BOM.

All core components of a computer system can be conveniently obtained from a single source. With the preconfigured and matched bundled solutions, customers of Bicker Elektronik save themselves a lot of time and money for product qualification and thus shorten time-to-market within the system development.
