StrainBook/616 Product Power Supplies
Item Name/Description Capacity
TR-40U AC Power Adapter
(shipped with StrainBook/616 & WBK16)
90-264 VAC input;
3.33 A @ 15 VDC *
DBK30A Rechargeable Battery/Excitation Module (optional) 12-14 VDC, or 24-28 VDC
3.4 A-hr @ 14 VDC
DBK34A UPS (uninterruptible Power Supply)/Battery Module
(optional)
12 VDC, or 24 VDC
5.0 A-hr @ 12 VDC
Other 10 to 30 VCD source, such as a vehicle battery via a
CA-116 cable.
Depends on source
* Note that some earlier TR-40U units have a limit of 2.7 A @ 15 VDC.
Input voltage to the StrainBook and to the WBK16 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 (some earlier units are rated at 2.7 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 Ahr; car batteries
have much higher capacities. The basic formula for battery life is:
Runtime (hr) = Battery capacity (Ahr) / 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 critical.
