## **Parallel and Redundant Operation** 

To increase the available power the DSR75 can be used in parallel configuration with other matching DSR75 power supplies. 

Up to five DSR75 power supplies can be connected in parallel without the need of a redundancy module or isolating diode. 

- 1) Each power supply should be separately fused on the AC input. 

- 2) Set output voltages to the same level within ±100mV based on same loading. 

- 3) Enable switch from “Single” to “Parallel” on the front panel of each power supply. 

- 4) Check individual DSR75 status via green “OK” LED 

**==> picture [148 x 151] intentionally omitted <==**

+<br>AC<br>Unit A<br>-<br>DC +<br>Load<br>+<br>AC -<br>Unit B<br>-<br>DC<br>**----- End of picture text -----**<br>


- 5) Enable and disable all power supplies simultaneously. 

Notes: 

- a. Simple parallel configuration will potentially overload individual units in the event of unit disconnect or failure. 

- b. For higher system integrity DSR75 outputs should each be protected by an isolating diode or circuit breaker. 

- c. Redundant configuration can be used for higher system reliability. In this configuration of 1+1 to share loading the outputs must be protected from each other. 

A peak load can be used for a certain period after which the output goes into overload mode. Overload operation is trip and restart. The peak load duration depends on the value of the load, e.g. a peak load of 150% can be taken for approximately 3s. After this time the output will turn off for approximately 7s before turning back on. 

If the load has reduced to 100% or less than normal operation is resumed. If the load remains at 150% then the output is maintained for a further 3s before turning off for 7s. See example plot below. 

**==> picture [135 x 33] intentionally omitted <==**

**----- Start of picture text -----**<br>
3s<br>150%<br>7s<br>**----- End of picture text -----**<br>


If the peak load is less than 150%, the duration of the peak can be longer than 3s before the output turns off, for example, a peak load of 130% could typically be taken for up to 13s and a peak load of 140% could typically be taken for up to 5s. The off duration is always approximately 7s. 

Average power is not to exceed nominal output power.
