How are WaveBook Systems Powered?
Power supply input voltage to the WaveBook and to the system modules, e.g., WBK10A, WBK14,
WBK15, WBK16, WBK17, WBK18, WBK40, and WBK41 must be in the range of 10 VDC to 30 VDC
and can come from an appropriate AC-to-DC adapter or a battery option. The latter includes DBK power
modules and batteries in the range of 10 VDC to 30 VDC.
Note: Power supply input to the WBK25 Ethernet Module must be in the range of 10 VDC to 20 VDC.
Available AC-to-DC adapters include the TR-40U (supplied), which has an input of 90-264 VAC and a
output rating of 2.2 amps @ 15 VDC.
Battery options include the DBK30A, DBK34A, and other 10 to 30 VDC sources, such as car batteries.
The DBK30A provides 14 VDC and when fully charged has a storage capacity of 3.4 A
⋅hr; car batteries
have much higher capacities. The basic formula for battery life is:
Runtime (hr) = Battery capacity (A
⋅⋅⋅⋅hr) / Current load (A)
System cards, e.g., WBK11A, WBK12A, and WBK13A, get power from their host WaveBook or their host
WBK10A expansion module.
Before connecting your system to power, you need to know the power requirements of your specific system.
A calculation method that incorporates the use of worktables is presented in Chapter 2 of the WaveBook
User’s Manual (p/n 489-0901).
Reference Notes:
• In the WaveBook User’s Manual (p/n 489-0901), the System Setup and Power Options
chapter includes examples of power connections for different WaveBook system
scenarios. In these examples the included TR-40U power adapters are used.
• In the WaveBook User’s Manual (p/n 489-0901), the WaveBook Operation Reference
chapter includes discussions of power supplies other than the TR-40U.
How are WBK Modules Mounted to other Modules or to WaveBooks?
Using Fastener Panels to Stack a WaveBook and two WBK Modules (use of the handle is optional)

The fastener panels and associated
screws are from fastener-panel kit,
