mW
DBK33
7500 mW
DBK34
5 A-hr in 12 V mode; fused at 8 A
DBK34A
5 A-hr in 12 V mode; fused at 8 A
Use the following procedure and table to calculate the required system power.
1. In the Quantity column (5th), list the number of DBKs of that type in your system.
2. In the Sub Total column (7th), enter the product of column 5 and column 6 (mW).
3. Add the Sub Total column, and enter the sum at the bottom right of the table.
This result is your power requirement in mW.
DBK32, DBK32A, and DBK34 cannot supply +5 VDC. In cases that require +5 VDC, if
the +5 VDC requirement exceeds 500 mW from a LogBook or Daq device, then a DBK33
must be used. Note that DBK33 can supply 1000 mW at +5 VDC.
Note: The DBK34 has an 8 amp fuse, and has a capacity of 5 A-hr when in the 12V mode,
and a capacity of 2.5 A-hr when in the 24V mode.
