2
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 nom is not exceeded.

Measured according to IEC/EN 61204 with a probe according to annex A

See Dynamic Load Regulation

See Output Voltage Regulation of Double-Output Models
6
For battery charger applications, a defined negative temperature coefficient can be provided by using a temperature sensor
(see Accessories), but we recommend choosing special battery charger models.
7
Especially designed for battery charging using the battery temperature sensor (see Accessories). Similar models see table 7b.
Vo1 is set to 25.68 V ±1% (R-input open).
6
Breakdown voltage of the incorporated suppressor diodes (1 mA). To exceed Vo BR is dangerous for the suppressor diodes.
