Parallel use to increase output power
Devices of the same type PS9731-2410-0000 can be connected in parallel to increase the output power.
- The output voltage of all power supplies shall be adjusted to the same value (±100 mV) in “Single Use” mode with the same load conditions on all units, or the units can be left with the factory settings.
- After the adjustments, set the device to “Parallel Use” mode, in order to achieve load sharing. The “Parallel use” mode regulates the output voltage in such a manner that the voltage at no load is approx. 4% higher than at nominal load. See also chapter “Output”.
- If more than three devices are connected in parallel, a diode, a fuse or circuit breaker with a rating of 15 A or 16 A is required on each output. Alternatively, a diode or redundancy module can also be utilized.
- The ambient temperature is not allowed to exceed +60 °C.
Restrictions
- Maintain an installation distance of 15 mm (left/right) between two devices.
- Avoid installing devices on top of each other.
- Do not use devices connected in parallel in installation positions other than the standard installation position or under other conditions that require a reduction in the output current (e.g., installation altitude).
- Pay attention that leakage current, EMI, inrush current will increase when using multiple devices.
