3.4.7. PSU 50W (12V 5A) (96-300048)
The power supply unit is a switched-mode type capable of supplying 12V DC at 5Amps continuously.
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.
