Overview
DBK30A Front Panel
DBK30A contains two rechargeable nickel-cadmium batteries and shares the same base dimensions as
other LogBook, DaqBook, and related DBK module products, allowing for convenient stacking with
included splice plates and dual-lock tabs.
The included power adapter converts AC power to 24 VDC for charging DBK30A’s two battery packs.
Automatic charging circuits recharge the internal batteries quickly and safely when connected to the
supplied AC adapters. For trouble-free operation you must fully charge the batteries before use. 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.
