Parallel/Series Connection

More than one unit of the same model can be connected in a parallel or series configuration.

Table 3.2 below shows the total number of units that can be connected in each configuration.

The power supplies can be set up in master/slave mode so that the master unit can control all

other power supplies in the parallel or series connection.

Note: Master/slave configurations and RS-485 connections must be properly set up prior

to controlling the power supplies in parallel/series connection. However, RS-485

does not have to be set as the Communication interface for master/slave operation

to function.
