AC-DC Power Supplies
The EPL225 series maximises efficiency across the load range and minimises no load power
consumption minimising heat dissipation, reducing running costs and enabling compliance with the
latest environmental goals and legislation. Fully approved for ITE and Industrial applications the
EPL225 provides up to 150W when convection cooled and up to 225 W when force cooled at just
10 CFM. A 12 V 0.5 A fan supply is included to support force cooled applications. The small
footprint, low profile, low noise and comprehensive safety agency approvals allow this versatile
product to be used in a wide range of ITE and industrial applications.
