temperature exceeds 70°C. The power supply unit is designed with a 30% reserve
even under the maximum load.
Power supply types
Internal 90 – 260V / 50 – 60 Hz (output 5V / 30A).
2x Internal 90 – 260V / 50 – 60 Hz (output 5V / 30A) (redundant).
Internal 48 DC (output 5V / 30A).
The type of the power supply unit to be used depends on the part number.
