Burleigh PZ-70M High Voltage DC Amplifier

The Burleigh PZ-70M High Voltage DC Amplifier delivers stable, low-noise output for driving piezoelectric devices in precision positioning and optical control applications. With selectable voltage ranges up to 1000 V and a 40 dB gain stage, It has the output authority required for high-impedance piezoelectric loads across laboratory and industrial environments.

Technical Specifications

Output Voltage: 0–500 V (Load ≥ 50 kΩ); 0–1000 V (Load ≥ 100 kΩ)

Frequency Response: DC–1 kHz

Gain: 40 dB

Display: 4-digit digital readout

Status Indicator: Limit notification LED

Control: Reset switch

Key Features Dual voltage modes allow selection of output range based on load impedance, optimizing performance across different piezoelectric actuator configurations. The DC–1 kHz bandwidth accommodates quasi-static positioning and moderate-speed servo operations. A 4-digit display provides real-time voltage monitoring, while the limit LED flags output constraints during high-demand operation. Reset functionality enables safe recovery from saturation conditions.

Typical Applications

Precision piezoelectric actuator control

Optical alignment and beam steering

Mechanical positioning systems

Laboratory instrumentation requiring high-voltage piezo drive

Compatibility & Integration Designed specifically for piezoelectric devices with high input impedance. Ensure actuator voltage rating matches the selected output range - do not apply the PZ-70M to actuators rated below the operating voltage. Burleigh piezoelectric actuators use LEMO connectors as standard for amplifier integration. Coordinate power supply specifications with system requirements before installation.
