Introduction
The 40K is a fast and versatile galvo scan system, based on moving magnet galvanometers,
with a small and rugged dual channel closed loop diver . The system runs at pretty low voltage,
and can be implemented in almost any existing or new application. With it's driving speed of up
to 60k with the ILDA test pattern, displayed at an angle of 4-5 .
The standard delivery package contains driver , power supply and input cable .The driver
is presetted to the included galvos, but has to be retuned slightly before first use. This can be done
by using the three adjustment trimmers on the driecard. Please note, that the galvos are not set for
maximum speed at small scan angle, but set to a usable angle of 20 at 38Kpps.
The cable
High speed galvanometers demand forspecial cables, which are shielded an separated between
motor and position detector. Cable lengths up to 100cm are allowed. We recommend a cable
length of maximum 50cm.
Power source
Power source is not very critical and has minor influence on speed and quality of the complete
scanner system .Even if a standard transformer with a bridge and caps will do, We
recommends a stabilized or switched power supply. The driver board is able to run between +/-
24VDC to +/-28VDC, at 1A each. Recommended power supply is the PSU with 2x24VDC.
If you use transformer andbridge, then make sure to have minimum 10,000 uFcaps per voltage,
better 40,000 uF, parallel with a 100uF for fast peaks. Do not use extra capacitors at switching
power supplies.
Polaritiy of connecting power tothe driver is important. No warranty if connected incorrect.
The measuring procedure
The 40K was measured with Mamba Black with USB-Box, running at the desired output
speed, using the standard ILDA test pattern. Laboratory power supply at +/-24VDC, room
temperature. Windows PC with Mamba Black , 12/30k ILDAtestframe. It was also tested
afterwards with pangolinLD2000, running thesame test pattern. 5x10x0.7mm mirrorwas used
during measuring period. Tests showed a slight decrease of performance at about 5 by using a
larger 6x11x0.7mm mirror. The galvos where fixed in the standard mounts on an aluminum
baseplate, no forced cooling.
