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.
