LAMBDA ADDS MEDICAL AND HEAVY DUTY VERSIONS TO HWS POWER SUPPLY RANGE

Lambda’s new HWS-ME medical supplies are available with ratings from 30W to 1500W, while the heavy-duty versions are offered with ratings from 50W to 1500W. All models of HWS feature exceptionally compact construction, typically requiring 60% less space than previous generation products, and all are suitable for operation from inputs in the range 85-265VAC at 47-63Hz, or 120-370V DC (except 1500W models), without the need for switching or adjustment.

HWS-ME power supplies for medical applications have EN60601-1 / UL60601-1 approvals for basic isolation and have leakage current less than 500 uA. Models up to 300W also meet Class B EMC requirements. They are, therefore, a versatile, space-saving and cost-effective choice for use in non-patient connected equipment such as MRI scanners and X-ray machines.

Output voltages for medical supplies rated up to 150W cover the range 5V to 48V, with a smaller range of output options offered for 300W, 600W and 1500W models.

The HWS-HD heavy-duty supplies are ideal for use in roadside cabinets, road signs, ticketing machines, automatic barriers and similar demanding applications. The units will start up at temperatures as low as – 40°C depending upon input voltage and load conditions.

Their ability to withstand adverse environmental conditions is further enhanced by a conformal coating which is applied to both sides of the printed circuit boards. The units also meet MIL standards for vibration and shock (MIL-STD-810F).

HWS-HD power supplies are available with output voltages from 3.3V to 48V in versions rated at up to 600W, and 12V to 48V in 1500W versions.

“The introduction of these new medical and heavy-duty models brings the proven benefits of our HWS products to a whole new range of applications,” commented Lambda Product Manager, David Buck. “In addition to small size, these important benefits include high efficiency, exceptional reliability and, of course, very competitive pricing.”
