Power Supplies
The power supplies that can be used with WaveBook setups are listed in the following table.
WaveBook Product Power Supplies
Item Name/Description Capacity
TR-40U AC Power Adapter (shipped with WaveBooks & WBK Modules) 90-264 VAC input;
2.2 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
DBK30A - Rechargeable Battery Module
DBK30A Front Panel
DBK30A contains two rechargeable nickel-cadmium batteries for use with WaveBook, expansion WBK
modules, and transducers. DBK30A shares the same base dimensions as other WaveBook products,
allowing for convenient stacking. Note that stacking can be easily accomplished with the included splice
plates.
The power adapter (included) converts AC power to 24 VDC for charging DBK30A’s two battery packs.
Automatic charging circuits recharge the internal batteries quickly and safely. The charged battery runtime
depends on the current load and mode of operation.
An internal slide switch (SW2) determines the unit’s mode. The two modes are:
• 14 VDC Mode (default)
• 28 VDC Mode
You should check the power requirements of each component in your system, and then
verify that the power source can provide sufficient power to meet your runtime
requirements.
Fully charge DBK30A’s batteries before use.
