Battery power supply
Choosing the battery power supply
Printer usage determines the choice
of battery power supply.
The battery capacity is counted in
ampere-hours (AH) and is deter-
mined by the following factors:
-
print speed
-
black/white-balance
-
supply voltage
-
label size
-
the number of printed labels per
hour
A (constant)
gives the actual consumption when printing in 100 % black (choose
the value from the table which corresponds to the applicable supply voltage).
W (constant)
gives the current which is consumed when the printer is switched on
but without printing taking place (choose the value from the table which corre-
sponds to the applicable supply voltage).
P
ave
= Supply voltage (U) x A(constant) x (black/white-balance in %) + W(constant)
In order to determine which battery that
shall be used P
ave
must first be established.
P
ave
indicates the average power
consumption during printing.
When calculating P
ave
determine the
voltage (U) and the average black/white
balance in %. For most purposes 25 % is
a suitable value. Thereafter, the formula
below can be used.
