Input voltage to the system modules (WaveBook, WBK10/10H, WBK14, WBK15, and WBK16) must be
in the range of 10 to 30 VDC and can come from an AC-to-DC adapter or from a battery. System cards
(WBK11, WBK12, or WBK13) get power from their WaveBook or WBK10/10H expansion module.
Available AC-to-DC adapters include the TR-40U (supplied), which has an input of 90-264 VAC and an
output of 2.50 A @ 15 VDC.
Battery options include the DBK30A or other 10 to 30 VDC source such as a car battery. 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)
Battery life and performance depend on various factors including battery type, condition, charge
level, and ambient temperature. Be sure you consider these factors, especially when runtime is a
critical.
