Lambda has extended its HWS family of compact single-output power supplies to include models that are approved for use in medical equipment, and others that perform reliably in the harshest of operating environments. The 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 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 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 suitable 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.
