300W AC-DC Plug-in Power Supply Module with Convection Cooling Rugged Industrial Quality LOT 65-EH Series • • • • • Rugged industrial quality Full electronic protection Convection cooling Field-proven design Hot swappable, N+1 redundant This rugged, industrial quality AC-DC plug-in power supply utilizes field-proven technology to generate the required output power. It is a mature design with a track record in numerous applications. A built-in redundancy diode allows parallel connection to achieve higher output power or N+1 redundant operation, including hot insertion. Cooling is by natural air convection. Heat generating components are installed on an aluminum heatsink block, which is connected to the heatsink plate on the side of the module. This also provides exceptional mechanical ruggedness. The input and output are filtered for low noise. Full electronic protection, low component count, large design headroom, and the exclusive use of components with established reliability contribute to a high MTBF. The unit is manufactured at our plant under strict quality control.
