The CL40 series is a family of 40W (50W peak) external switching power
supplies. The CL40 enables the system specifier to optimise the design for
several reasons. Firstly, because the power supply offers pre-approved SELV
(Safety Extra Low Voltage) outputs, the submission of the apparatus for safety
approval is simplified. This represents a significant saving of time and money.
Secondly, the task of integrating the power supply into the mechanical design is
eliminated, presenting further savings in time and money by ensuring a shorter
and simpler design cycle. This means that your product gets to market faster.
These advantages are complemented by universal input, CE mark, IEC950, UL,
CSA, VDE and BABT approvals, to complete a worldwide packaged power
solution suitable for a wide variety of low power, desktop applications.
