Data Sheet

CPS20.241-60
C-Series
24V, 400W, DC/DC CONVERTER
3. AC-INPUT
Do not operate this DC/DC converter with an AC-input voltage. Use the CPS20.241 or CPS20.241-C1 unit instead.
4. DC-INPUT
Use a battery or a similar DC source. A supply from the intermediate DC-bus of a frequency converter is not
recommended and can cause a malfunction or damage the unit.
