K-Cube Piezo Driver
The way the signal driving the EXT IN input controls the unit depends on the operating
mode. In
open loop
mode, the voltage on the EXT IN input can be used to drive the
high voltage amplifier directly and the output voltage is proportional to the driving
voltage. In
closed loop
mode, EXT IN can be used as a position feedback input,
designed to be driven by an external position reader (such as the KSG101 Strain
Gauge Reader). These operating modes are detailed in Section 5.3. to Section 5.6.
MONITOR
(SMA connector)
– This low-voltage (0 to +10V), output can be used to
monitor the signal at the HV OUT high voltage output. In its most common use, it can
be connected directly to an oscilloscope to observe the waveforms or voltage levels
present at the high voltage output.
3.3.2 Supply Voltage and Current Requirements
Caution
In open loop mode, the EXT IN connector drives the HV amplifier circuit
directly. If an external input is used, the output voltage limits (i.e. 75V, 100V or
150V) can be exceeded.
Note
The KPZ101 has two main, selectable output voltage ranges of 0 to 75V or
0 to 150V, to allow driving piezo actuators with different drive
requirements. (In addition, there is a 100V limit for operation under
software control). Regardless of which range is selected, the input and
output voltage range on the EXT IN and MONITOR connectors is always
0 to +10V full scale.
Note
Thorlabs supply a variety of SMA to BNC and SMC to BNC adaptor and
extension cables. Please see our catalog, or visit www.Thorlabs.com for
