WARNING!
General
Precautions
♦
All insulation of leads connected to output terminals should have at least a 300V rating.
♦
Do not use clip leads in the conne
ctions
. They are very dangerous for high
-
voltage work.
Acceptable Load Types
♦
This
Amplifier
is designed to drive ca
pacitive loads o
nly. Do not use with resistive loads.
The driver
will only work properly when a capacitive load is connected to the output.
♦
Never connect an inductive or a resistive load to the unit. This would cause a short
-
lived
high
-
current pulse at
the output
and would damage the
unit.
Short Circuit Damage
♦
Although the
VF
-
150
OEM
is protected against a shor
t
circuit on the output, it is
recommended that a short circuit condition be avoided.
♦
Never connect an "earth ground" lead (e.g., an oscillosc
ope ground lead) to the output
terminal. This
can cause high
current
at the output
and
possible
damage to the unit.
♦
If the u
ser desires to observe
the
output signals
using a voltage meter or an oscilloscope, the
user must ensure that the meter or
oscilloscope has an in
put impedance of at least 1 M
Ω
.
Smaller
input impedance
s
could
damage the unit
.
RECOMMENDED OPERATION
Intended Use
DSM’s
VF
-
150
OEM
is intended to drive
piezoelectric (capacitive)
loads
of the following types:
•
O
perating range
–
100 to +10
0
V
•
O
perating range
–
4
0 to +200
V
•
O
perating range
–
3
0 to +1
5
0
V
•
Operating range
–
20
to +120
V
E
xternal power
supply determines configuration.
The input rail voltages should both be
5 to 10
V
olts
beyond the operating range
. For example if
-
30 to +150
V
olt
operation is requred
,
typical
rail voltages
would
be
-
40
and
+160
V
olts
.
Two modes of operation are supported; the output
voltage can be set using an analog input voltage with nominal gain of 58, or the output voltage
can be set using a
serial communication interface. Operation is decribed in more detail, below.
