5.11 24V 400W Flat-Pack Power Supply (96-300011)
5.11.1 Description
The power supply unit is a switched-mode type capable of supplying 24V DC at 16.0Amps
continuously. Equipment of this type typically requires approximately 10.0 Amps at 24V
DC, so the PSU will be used conservatively ensuring a long operational lifetime.
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 24.5V.
All the PSU’s 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. No drawings of the PSU are available.
