A range of 30 Watt, single-output AC-DC power supplies has been announced by XP Power for use in medical applications. Competitively priced, the versatile EML30 series offers a variety of mechanical formats and mounting options.
Factors driving the demand for this type of unit are the desire for, and the development of, smaller portable medical equipment. Accordingly, the EML30 will find favour with customers requiring medical safety approvals and where the power source needs to occupy minimal space. It is also ideal where the requirement is for a Class II input type power supply and where no ground / earth connection is needed.
Models on offer include open-frame versions with either PCB mount or with connectors, encapsulated models with either PCB mount or screw terminals, and a DIN rail mount option. The open-frame PCB mount version measures 75,2 x 34,6 x 26,7 mm.
Output voltages of 3,3 V, 5 V, 9 V, 12 V, 15 V, 24 V, 36 V and 48 V d.c. are available. To power short-term, high-power loads, a peak current capability of up to 130% of nominal rated power output is available, so there is no need for designers to specify a more expensive, higher rated power supply.
The power supplies feature a wide operating temperature range of -25°C to +70°C, with no derating until above +50°C. Using convection cooling, the EML30 is able to provide full power without additional heatsinking or airflow.
This product series meets the requirements of EN60601-1:2006, ANSI/AAMI ES60601-1:2005 and CSA-C22.2 No. 60601-1:2008, offering 2 x MOPP between primary and secondary circuits. It also meets the limits for Class B conducted and radiated EMC specifications of EN55022 without the need for any additional external filtering components.
