    Applications Parallel connection to increase power rating To increase the power rating, SITOP PSU300M/300B power supplies of the same type can be directly connected in parallel. The following must be observed: ● The cables connected to each power supply at terminals "+" and "-" must have identical lengths and the same cable cross-sections (or the same impedance) up to a common external connection point (terminal strip) if possible.

    Applications 9.2 Parallel connection for redundancy Parallel connection for redundancy Connecting several SITOP PSU300M/300B power supplies in parallel for redundancy purposes is required if especially high demands are placed regarding the availability of a reliable 24 V power supply. Using the SITOP PSE202U redundancy module, two 24 V power supplies of the same type up to 20 A can be decoupled (Figure 9-2 Redundant configuration with two power supplies and one SITOP PSE202U redundancy module (Page 67)).
