HVA0510

Overview

The HVA0510 is a miniature, bipolar, zero-crossing high voltage amplifier from HVM Technology. It operates from a 5VDC input and produces an output voltage ranging from 0 to ±1000V in response to a 0 to 5V programming input. The module features excellent linearity and includes an enable pin for controlling the internal high voltage generator. Electrical specifications include a maximum output current of 100µA, steady-state input current under 100mA at no load, and load regulation less than 0.5%. Output ripple at full load is less than 1% of full scale.

Feature Summary

• Bipolar, zero-crossing high voltage output capability
• Integrated high voltage generator and amplifier requiring no external components
• Logic-controlled enable input for power management
• Proprietary ultra-compact resonant converter design

Applications

• Mass spectrometry
• Electrostatic chucks
• Pockel cells
• Electron microscopes

Procurement Notes

Verify the specific model suffix against the manufacturer's official documentation to confirm the exact output voltage rating and input voltage requirements. Ensure that the procurement channel provides genuine products with valid traceability records. Confirm that the delivered units match the electrical characteristics specified in the datasheet, particularly regarding output tolerance and ripple performance under defined load conditions.

Selection Notes

Select the HVA0510 when a 5VDC supply is available and a bipolar output range of ±1000V is required. This model is suitable for applications demanding fast response times and precise control via a low-voltage programming signal. Consider alternative models within the series if higher voltage ranges or different input voltages are necessary for the system architecture.

Part Context

The HVA Series consists of space-saving encapsulated packages designed for PC board mounting. The HVA0510 belongs to the subset of models operating on a 5VDC input, distinct from the HVA12XX series which utilizes 12VDC. The series is engineered for ease of use, integrating dual polarity generation and amplification into a single thermoset plastic enclosure.

Replacement Considerations

Direct replacements must match the 5V input requirement and ±1000V output capability. Verify compatibility with existing PCB footprints and thermal management solutions. Cross-reference pinouts to ensure the enable and program inputs align with the host circuit design.
