11.4.3.14. DC/DC Converter 96-200047
96-200047 is an O.E.M. high power device with a wide input range and 12.5 amp @ 12V (150Watts)
output capability used to derive a 12V fixed voltage power supply rail from a higher voltage supply, in
this case 12V. In the event of failure this unit should not be repaired, only replaced.

11.4.3.15. 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.
All the PSUs used in AFL Cell Enhancers are capable of operation from either 110 or 220V nominal
AC supplies. The line voltage is sensed automatically, so no adjustment or link setting is needed by
the operator.
