2 Power Supply Specification
The table below represents the minimum acceptable performance of the design. Actual
performance is listed in the results section.
Note 1: All measurements performed with 380 VDC input unless otherwise specified
Note 2: For output voltage tolerance and ripple see minimum/maximum allowed current
Note 3: Total peak DC output power will not exceed 365 W at 50
Note 4: Peak Main power is 340 W (excluding Standby)
Note 5: Absolute maximum Standby power is less than 25 W (excluding Main)
Note 6: Full load operation at room temperature beyond 10 minutes requires a 30 CFM
