Ultra-Compact Piezoelectric Linear Amplifier Supplies Power to Nanopositioning Actuators Mar 6, 2008
Piezo nanopositioning specialist PI offers the miniature E-831 OEM (add-on) piezo driver module (piezo power supply)
-- a very compact, cost-effective, single-channel, 4-quadrant power amplifier for low-voltage piezoelectric nanopositioning actuators (LVPZTs).
Small, Yet High Performance
The minute driver module (50x30x14 mm) is a high-precision amplifier and provides an output range of -20V to 120V, peak currents of 100 mA and 12 W peak power for dynamic linear operation or fast switching applications. The E-831 amplifier is well protected by two current limiters and a temperature sensor. The small size makes it an ideal add-on for space-constrained applications. The product is the smallest in PI's line of high-voltage and low-voltage linear PZT amplifiers.
High Reiability, Ideal for OEMs
It provides very high reliability tested in thousands of piezo motion control applications in the field. All of PI’s amplifiers can be controlled through a 0 to 10 V input and are compatible with NI D/A converter cards. PI also offers LabView™ Drivers for easy control and a special resolution enhancing software (HyberBit™) for National Instruments DACs.
The E-831 amplifier is short-circuit proof with both a low-speed current limiter of 50 mA and a high-speed (8 msec) current limiter of 100 mA. When the case temperature rises above 70 °C (can be reached after a few minutes with maximum current) an internal temperature sensor shuts down the output stage until the temperature drops below 60 °C. This operation mode is in-dicated by the active-high TEMP-OFL TTL status line.
PI is the industry leader in ultra-precision motion control devices for nanoscale manufacturing, test and research applications.
