6.4.6
Power supply requirements.
Power the central unit with an external regulated 24V power supply with the following
characteristics. The power supply must meet the UL1950 standard.
• Output voltage.
24 V DC (between -15% and +20%) and 2 A (including voltage ripple and noise).
• Output current. A
The continuous load current must be greater than the current consumed by the CNC (2 A)
(at the maximum temperature inside the electrical cabinet - enclosure - where the power
supply is).
• Load fluctuations (including the current peak due to the load).
The output voltage must not exceed the previous limits (20.4 V ÷ 28.8 V), due to load
fluctuations.
• Output voltage holding time after an instantaneous power interruption.
10 ms (for an interruption of 100%) / 20 ms (for an interruption of 50%).
