NOTES
1. At PLC (Power Line Cycle) = 1.
2. Following 15 minute warm-up, the change in output over 8 hours under ambient temperature, constant load,
3. PLC = Power Line Cycle. 1PLC = 16.7ms for 60Hz operation, 20ms for 50Hz operation.
4. Recovery to within 20mV of previous level.

I = 50W/(V
I = (50W – power consumed by channel #2)/(V
The power consumed by channel #2 is calculated as:
Channel #2 Sourcing Current: Power consumed = (V
Channel #2 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 #2)/5V; 3A max. (0–5V).
Derate 0.2A per volt above 5V.
