Other 10 to 30 VCD source, such as a vehicle battery via a
CA-116 cable.
Depends on source
Input voltage to the ZonicBook/618E and to the WBK18 expansion modules must be in the range of
10 to 30 VDC and can come from an AC-to-DC adapter or from another source, such as a battery.
Available AC-to-DC adapters include the TR-40U, which has an input of 90 to 264 VAC and an output
of 3.33 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)
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.
