Parallel use to increase power

Power supplies of the same type from the PS3xxx series can be connected in parallel to increase the output power.

• The output voltage must be set to the same value (±100 mV), or the units can be left with the factory settings.
• If more than three devices are connected in parallel, a fuse or circuit breaker with a rated current of 30 A or 32 A is required at each output. Alternatively a diode can be used.

Restrictions:

• Maintain an installation distance of 15 mm (left/right) between two power supplies.
• Do not install the power supplies above each other.
• In "Parallel Use" mode power supplies should only be used in the standard installation position (input terminals on the underside of the device, output terminals at the top), not in other installation positions or under other conditions that require a reduction in the output current (e.g., installation altitude, operation at temperatures about +60°C, ...).
• Note that leakage current, electromagnetic interference, inrush current, and harmonics increase when using multiple power supplies.
