automatically once settable window (±0 to ±8 volts) around normal voltage exceeded.
I = 50W/(V
I = (50W – power consumed by channel #1)/(V
The power consumed by channel #1 is calculated as:
Channel #1 Sourcing Current: Power consumed = (V
Channel #1 Sinking Current: Power consumed = 5V × (sink current).
0–5V: 3A max.
5–15V: Derate 0.2A per volt above 5V. Compliance setting controls sinking.
Available Current = (50W – Power consumed by channel #1)/5V; 3A max. (0–5V)
