Specifications
Power • Maximum continuous average output power: 196 W.
• Peak power: 276 W.
¯ Peak must not last longer than 30 ms.
¯ Limitation of peaks per minute: max. 3.
Voltage range
¯ Precondition to be able to measure the output voltages correctly, is, that
a minimum output current of 0.3A is drawn from the 5 V output (minimal
load). This is e. g. reached by connecting the CPU board to the power supply.
¯ At the 24V and 45 V outputs, no minimum output current is required to
measure the voltages correctly.
Current range
¯ The 24V output provides a continuous current of 6A for 10 s in typical
operation.
¯ Without a minimum load at the 5 V output, the voltage at 24 V and 45 V
supply should not be higher than 28V and 50 V respectively.
