General Description
3
Deltas new MDS-300ADB48 enclosed design offers a high energy density (8.8 Watts/in ) 3.5x5.5 inch design for Type BF patient
access medical products. With operating parameters of 90 to 264 Vac universal input voltage, temperatures of -10 to +70 degrees
centigrade, and altitudes of up to 5000 meters (16,400 feet), the design is well suited for a variety of both medical and non-medical
applications. Other features include input surge of 300 Vac, low leakage current, no-load input power < 0.5 Watt, and 800K hour MTBF.
This product is certified for EMC standards EN 55011 for industrial, scientific and medical (ISM) radio-frequency equipment, and EN
55032 for Industrial Technology Equipment (ITE) radio-frequency equipment. In addition, only recognized Japanese capacitors are
used to ensure long product life.
An enhanced feature set, includes a 5 Volt/0.5 amp standby output, remote on/off, remote sense, and a power good signal that are
included as part of the standard product.
The design, which has protection against shock compliant with 2XMOPP and Type BF requirements, has both medical (with risk report
available), and ITE safety approvals, including cURus(US&Canada) /TUV/GB(China); plus, CB certificates with all national deviations.
Full compliance with RoHS Directive 2011/65/EU for environmental protection is included.
