Engineered for industrial reliability

This DC-DC high-voltage power supply module converts a 12 V input into a precisely regulated 0 to 3 kV output with a maximum current of 5 mA. It is built for engineers and technicians who need stable, low-noise power in demanding environments such as X-ray systems, spectral analysis, semiconductor manufacturing, and particle accelerator research. The metal enclosure provides effective heat sinking and zero EMI emissions, ensuring clean operation around sensitive instrumentation.

Thermals, noise and power draw

The unit accepts an input voltage of 12 V ± 1 V and draws between 400 mA and 1.8 A depending on load, while delivering a reference voltage of 5 V ± 0.05 V for control circuitry. Its linear topology and metal housing dissipate heat without forced airflow, eliminating acoustic noise and electromagnetic interference that could disrupt analytical measurements or imaging processes. Electronic shutdown control allows immediate output inhibition for system protection.

Integration and system fit

A 0 to 5 V control voltage scales the output linearly, enabling straightforward integration into automated test rigs or closed-loop control systems. Standardised connectors and a compact footprint simplify installation inside existing enclosures, freeing valuable rack space for other subsystems. The module is not suited for applications requiring higher output current, adjustable polarity, or AC mains input without additional front-end conversion.

Questions about this item

How do I install the AHV12V3KV5MAW and what is the common mistake?

Connect a 12 V source capable of 400 mA to 1.8 A to the input terminals, then apply a 0–5 V control signal to the CTRL pin; the frequent error is using an input supply that cannot sustain the required current range.

What maintenance or replacement will this supply need later?

The metal enclosure provides zero EMI and acts as a heat sink; keep ventilation paths clear and verify the reference voltage remains within 5 V ± 0.05 V during periodic checks.

What limit appears first during sustained high-voltage operation?

The output current is capped at 5 mA, so any load demanding more will hit that ceiling before thermal or voltage regulation limits are reached.
