HVA1230

Overview

The HVA1230 is a miniature, bipolar, zero-crossing high voltage amplifier from the HVM Technology HVA series. It operates from a 12VDC input and produces an output voltage ranging from 0 to ±3000V in response to a 0 to 5V programming input. The device features excellent linearity, current sourcing and sinking capabilities, and an enable pin for controlling the internal high voltage generator. It is housed in a space-saving encapsulated package designed for PC board mounting.

Procurement Notes

Verify the specific model suffix against the manufacturer's official documentation to confirm input voltage requirements and output voltage range. Ensure that the procurement specifications align with the electrical characteristics defined in the datasheet, particularly regarding load regulation and output ripple. Confirm compatibility with the intended application environment, including operating temperature ranges and packaging requirements.

Selection Notes

Select the HVA1230 when a 12VDC input supply is available and an output voltage up to ±3000V is required. Consider this model for applications needing bipolar output with zero-crossing capability and precise control via a 0-5V programming signal. Evaluate the need for current sourcing and sinking capabilities and ensure the operating environment falls within the specified temperature range.

Part Context

The HVA1230 belongs to the HVA series of high voltage amplifiers manufactured by HVM Technology. This series includes models with 5V or 12V inputs and output voltages of ±1kV, ±3kV, or ±6kV. The series is characterized by its compact size, ease of use without external components, and proprietary resonant converter design for low noise and high reliability.

FAQ

What is the function of the Enable pin on the HVA1230?

The Enable pin is a logic-controlled input where a logic low signal enables the internal high voltage generator.

How does the HVA1230 handle output voltage relative to the programming input?

The output voltage is proportional to the programming voltage (0 to 5V), producing negative full scale to positive full scale output, and is independent of the input power voltage.
