Same conditions for both outputs.
If the output voltages are increased above
Vo
nom via R-input control, option P setting,
remote sensing or option T, the output
currents should be reduced accordingly so
that
Po

See:
Dynamic Load Regulation.
For battery chargers a defined negative
temperature coefficient can be provided, see
Accessories.
See:
Output Voltage Regulation of Double
Output Models.
LK models have an additional low-frequency
ripple at twice the input frequency (< 5 mVpp).
