Yes, but the heat sink on the PS100 may get warm, so be careful. An older Campbell Scientific charger that is 15 to 18 Vac or Vdc may run cooler. To charge from a 24 Vdc power source, Campbell Scientific recommends using the PS150, CH150, PS200, CH200 or CH201.
The 29796 or 22110 can be used with the PS100 if it limited to an "average current of no more than 0.25 A." Short-term peak currents can exceed 1 A without problem.
