8.4 ALTERNATIVE POWER SUPPLY ARRANGEMENTS
The CP130 is designed to be operated from a 9V to 36V voltage source that is capable of supplying
the primary power for the printer.
The electrical specification for the power supply input of the CP130 printer is:
Input Voltage Range:
+9V to +36V (internal over voltage at 37V and reversal protection)
Supply Current Requirement: 50mA
( Printer in Idle Mode )
( typical @24V in ) 1A average ( Printer Printing )
4A peak ( Printer Printing )
N.B. The average and peak current requirements can be adjusted by firmware control codes.
See the Programmer Guide for details.
The recommended power supply input is either a 12V or 24V vehicle battery, this allows the printer to
perform at its best. However, the printer will automatically accommodate any DC input voltage in the
range 9V to 36V. In addition, power supplies with lower current capacities may be accommodated by
varying the internal Power Save parameter. See the Programmers Guide or contact the factory for
more details.
