For the power redundancy application—commonly used in process control industries—users can parallel two power supplies even though only one could meet the power needs of the control panel. If a power supply fails, the second stand-by power supply takes over. For the second application—typically used in heavy manufacturing automation—parallel connectivity of two power supplies enables users to deliver power required by a load beyond what a single power supply can deliver. List price of the CP DM 10 10A Diode Module is $90, while the CP DM 20 20A Diode Module is list priced at $140.
