5.5.1 Output channel characteristics
PM2811/12/13
Each individual output channel can supply power accordin
to its output
characteristic. Fi
ure 5.5.1 below
ives you information about the three possible
output channel characteristics. The power output is rated and limited accordin
to
the formula: P (power) = U (volta
e) x I (current).
As an example look at the 30V/10A/60W output channel ratin
s:
• For volta
es from 0 to 6V the current can increase to its maximum of 10A. For
volta
es > 6 to 30V, the current can increase to its maximum alon
the stated
curve, e.
., 20V
ives maximum of 3A.
• For currents from 0 to 2A the maximum volta
e can be 30V. For currents > 2
to 10A, the volta
e can increase to its maximum alon
the stated curve, e.
.,
5A
ives a maximum of 12V.
