XP Power¹s latest compact desktop AC/DC power supply, PDM60, provides Class
II system protection. Safety approvals include UL609501 and EN609501 for
industrial and IT applications, and UL60601-1 and EN60601-1 for medical
systems. With 4000 VAC isolation and low leakage current, the PDM60 is
ideally suited to both medical and commercial use. Measuring just 135 x 65 x
41 mm (5.3 x 2.5 x 1.6 inches), it has an improved power density over
previous products and is well matched to portable applications.
With Class II systems, a grounded AC input socket is not required for normal
operation. Class I systems rely on both insulation and an earth connection
as a means of protection. Normally, Class II products require increased
printed circuit board (PCB) space to provide further insulation but the
PDM60 has been engineered to be as compact as Class I products but with the
advantage of Class II isolation. Increasingly, equipment that is used in a
variety of operating situations, including the home, are specified as
requiring a Class II power supply. Class II provides proper safety
protection where the availability and integrity of an earth cannot be
guaranteed.
The PDM60 is available in seven output voltage models, from 12V to 48V with
corresponding output currents from 4.6A to 1.25A. Non-standard output
voltages and connectors can also be accommodated to suit customer
requirements. Output protection includes over-voltage, overload and
short-circuit features. The power supply can operate at full power from -10
to 40 degrees C without de-rating and to 60 degrees with de-rating.
