SL Power Electronics Corporation, the company established following the merger of Condor DC Power and Ault, announces a 10 to18W switch mode power supply family designed to help medical equipment OEMs replace linear power supplies with a single, energy-efficient, globally compatible switch-mode power unit. The Ault MW172 family features a 100VAC to 240VAC Universal Input range and meets the Environmental Protection Agency’s (EPA) ENERGY STAR requirements for energy efficient products. As an ENERGY STAR partner, SL Power Electronics produces external power adapters that meet the program’s requirements for efficiency and no load power consumption.

External power products that meet the new EPA/ENERGY STAR requirements are an estimated 35 percent more efficient than conventional models. The Ault MW172 series is available in desktop or wall plug-in styles with output voltage models in 3, 5, 9, 12, 15, 18 and 24 volts and is a low-cost option for leading medical device OEMs. Competitively priced at $9.67 in a 1,000-piece OEM quantity, the Ault MW172 provides an affordable, energy-wise option for medical OEM design engineers.

As a wall plug-in, the MW172 is designed with interchangeable blades – available for North American, European, United Kingdom and Australian markets.

“The Ault MW172 provides design engineers a logical alternative to conventional and larger linear power supplies. The MW172 is in a popular power range for linear power supplies and offers greater versatility due to its wide range, good value and smaller size,” said Nigel Davies, European Managing Director, SL Power Electronics Corp. “Now medical OEMs can replace a host of linear power supplies with a single switch-mode unit that they can use worldwide to power their medical devices.”

SL Power Electronics anticipates that the Ault MW172 will prove popular for powering MRI LCD displays, life care patient monitors, home care diagnostic systems, and other portable health care devices.

“As the home health care market grows, OEMs are designing portable equipment that can travel from the operating room, to the patient’s room, to the patient’s residence,” explained Davies. “We believe our products and value-added services are well suited to medical OEMs because we understand their stringent product requirements and safety agency certification issues.”

To help reduce OEM product design-to-production cycle time, the CE-compliant Ault MW172 meets safety agency requirements, including UL60601-1 and IEC/EN60601-1. In addition, the foldback overcurrent and short-circuit features ensure output protection. Transient output response is 0.5 millisecond for 50 percent load change. Holdup time is 18 milliseconds at 120VAC and 100 milliseconds at 240VAC. All models also have low output ripple. SL Power Electronics Corp. also offers modified and custom designs to meet specific OEM requirements.
