Design of the 15-PSU/18-PSU
The power supply unit 15-PSU or 18-PSU provides two electrically isolated power supply circuits
for the CHALLENGER 15 or CHALLENGER 18. The 15-PSU or 18-PSU has a voltage output of 12V
and a factory pre-set power limitation.
Please refer to the drawing of the 15-PSU or 18-PSU in the appendix for details.
POWER SUPPLIES 12V:
Input
Voltage:
100-240V
AC
(optional
24VDC)
Output Voltage:
10,8 – 13,2V DC
Power:
2x30W
Input Frequency:
50-60Hz
