1. Introduction
1.1 Product description.
The 1A100 is a unique piezo actuator driver with no position sensor processing electronics on
board.
It consists of a precision high voltage amplifier, AC power supply, insulation transformers,
rectifiers, and voltage regulators. All this is compactly packaged in a 4-part aluminum case that
has the surface connected to ground through the AC cord.
The MOSFET amplifier is protected from excessive common mode and differential mode
voltages.
On the front panel the device offers manual control as well as an analog input for user control.
The level indicator can used to estimate the voltage applied to the piezo.
All front panel connectors have the outer side connected to ground (GND).
The HV output connector will deliver up to 150V (only positive polarity) on the center pin.
For applications where PC control is necessary we recommend the use of a D/A card to
generate the analog input voltage. Suggested manufacturers are Capital Equipment
Corporation (CEC), Keythley Instruments and National Instruments (NI).
The same front panel input can be used to drive the 1A100 directly from a function generator.
If the driving signal is bipolar the corresponding amplified negative part of the output will be
“clipped”. See the Operation paragraph for details.
The amplifier is pre-calibrated and has a gain factor of 30 in DC and quasi DC operation.
On the rear panel the user has access to the AC power plug and the ON / OFF switch.
The fuse is located inside the box.
The amplifier is delivered with this manual, power cord and a LEMO to blunt end cable.
Extension cables and adapters can be ordered separately.
