RE 30111/09.05
Meaning of the DIL switches
1)
Doubling of the maximum output current doubles the
adjustment range and the set biasing current.
2)
For f = 100 Hz, DIL switches S25, S26 and
S27 must be set to the “ON“ position.
3)
Up to component series 5X
Adjustment range of biasing current using potentiometer “Zw“
(R130):
I
max
= 800 mA → I
b
= 0 to 300 mA
I
max
= 1600 mA → I
b
= 0 to 600 mA
( ) valid for VT-VSPA1-1, component series 10
When switch BR22 is operated, the biasing current increases
by 50 mA or 100 mA.
Note (X):
Before commissioning the amplifiers, make sure that the DIL
switches on the printed-circuit board are set according to the
relevant application.
Adjustment options inedependent of the valve type (command value 2 and ramp time)
