Current mode configuration
The same PCB can be config-
ured for current mode heating.
It is needed to remove the
Jumpers JV1 and JV2 and to
introduce the Jumpers JC1
and JC2. It could be also usefull
to add a resistor RDC in paral-
lel to CDC because in this con-
figuration after initial start-up
you could have some striations
(visible dark rings) on the lamps
for a short period (a few min-
utes) particularly when the lamp
has been off for some time and
is cold. The value should in the
order of 100kOhm 0.5W.
We suggest the use of the Bal-
last Designer software to deter-
mine the values of the compo-
nents to use in this configura-
tion.
