21.3.2.15. 12V Switch-Mode PSU (96-300052)
No routine maintenance of the PSU is required. If a fault is suspected, then the output voltage from
the power supply may be measured on its output terminals. This is typically set to 12.2V. The
adjustment potentiometer will be found close to the DC output terminals.
The line input voltage is sensed automatically, so no adjustment or link setting is needed by the
operator.
