K Series with PFC Data Sheet
150 – 280 Watt AC-DC Converters
1
Same conditions for both outputs
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.
3
Measured according to IEC/EN
61204 with a probe annex A
4
See Dynamic Load Regulation
5
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.
7
Especially designed for battery
charging using the battery
temperature sensor; see
Accessories.
Vo1 is set to 25.68 V ±1% (R-
input open).
8
Breakdown voltage of the
incorporated suppressor
diodes (1 mA). To exceed
Vo BR is dangerous for the
suppressor diodes.
