7.2 Power supplies
B&R power supplies have either a single-phase or three-phase design. They provide a wide input voltage range
as well as a stable output voltage.

7.2.1 Single-phase power supplies
•
100 to 240 VAC wide-range input
•
Can be connected in parallel for increased capacity and redundancy
•
High degree of operational safety at full load and high MTBF (>500,000 h) due to long power failure bridging
•
International approval package
•
Wide temperature range from -25 to 70°C
•
Compact design and easy installation on the top-hat rail
7.2.2 Three-phase power supplies
•
400 to 500 VAC wide-range input
•
Reliable power supply even if one phase fails temporarily
•
High dielectric strength
•
Can be connected in parallel for increased capacity and redundancy
•
High degree of operational safety at full load and high MTBF (>500,000 h) due to long power failure bridging
•
International approval package
•
Wide temperature range from -25 to 70°C
•
Closed metal housing
•
Easy installation on the top-hat rail
