Connect DC-DC converters in parallel?

When a DC/DC converter or a AC/DC power supply is paralled on the output we recommend to use a series diode, that will insulate any eventual failure. There are two magor reasons to connect two or mor units in paralllel: Yes you can connect all Polyamp in parallel. It is recommended to use a series diode on the output to isolate any fault. There are two major reasons to connect in parallel: 1. To achieve more power than contained in one unit. By connecting two or more units in parallel you can achieve high power systems. As Polyamp can supply converters up to 1000-2000 W it is usually suitable for very large systems. 2. To get redundant operation N+1. If you need a very reliable power system, two converters or more can be connected in parallel. Each converter is then specified to carry the whole load or you have an N+1 configuration. The converters must have series diode and output alarms to provide fault indication in case of failure. For more information how to connect and precautions download the installation manual on the model you intend to use.
