30-Watt Medical Power Supply claims Smallest Footprint

March 5, 2015 By admin Comments are Off

XP Power plc today announced the EML30 series of 30-Watt single-output ultra-compact ac-dc power supplies designed for use in medical applications. The EML30 series claims the smallest footprint and the highest power density in the industry when compared to other similar 30-Watt power supplies with medical safety approvals. The EML30 series also claims more mechanical formats and mounting options than the competition. The open-frame PCB mount version measures 2.96 x 1.36 x 1.05 inches (75.2 x 34.6 x 26.7mm), offering a power density of 7.1 W per cubic inch.

Factors driving the demand for this type of unit are the desire for, and the development of, smaller portable medical equipment. Accordingly, the EML30 is designed for applications requiring medical safety approvals and where the power source needs to occupy minimal space. The EML30 is also suited where the requirement is for a Class II input type power supply and where no ground / earth connection is needed.

Exhibiting versatility, the EML30 is available in a range of mechanical formats. There are 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. These make life easier for designers by providing multiple mounting options to best fit their end system.

A wide range of eight single output voltages embracing 3.3-, 5-, 9-, 12-, 15-, 24-, 36-, and 48-Vdc 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 to +70 degrees C, with no derating until above +50 degrees C. Using convection cooling, the EML30 is able to provide full power without additional heat sinking or airflow. The EML30 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. Risk management files are available.

The series meets the limits for Class B conducted and radiated EMC specifications of EN55022 without the need for any additional external filtering components. The EML30 is priced $29.64 in 500 pcs quantities for the open frame model and is available from Newark, Digi-Key, or direct from XP Power and come with a 3 year warranty.
