500W AC-DC Plug-in Power Supply Module with Convection Cooling Rugged Industrial Quality HBC 419-EH Series • Rugged field-proven design • Industrial quality • Full electronic protection • Front panel test points & LED status • Convection cooled (no fans) This rugged, industrial quality 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 and 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. The front panel of the module has a power 'ON' LED indicator and test points. 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. ABSOPULSE power supplies are designed and built to customer requirements.
