Industrial High-Voltage Power Module

This DC-DC converter steps a 12 V supply up to a regulated 0‑500 V rail with a maximum output of 20 mA. It is built for engineers and technicians who need a compact high‑voltage source for scientific or industrial equipment. The metal enclosure provides shielding and heat dissipation for stable operation in demanding environments.

Control Voltage Sets Output

The output voltage tracks a 0‑5 V control signal, so the module delivers 0‑500 V proportionally to the input command. A 5 V reference with ±0.05 V tolerance ensures repeatable regulation, while the electronic shutdown pin allows instant disabling without cycling the main supply.

Integration Requirements

The unit requires a 12 V source capable of supplying 250 mA to 1.2 A depending on load. Standardised connectors and a compact footprint let it fit into existing racks or custom chassis. It frees designers from building discrete high‑voltage stages for X‑ray, spectroscopy, electrophoresis or thin‑film deposition systems.

Questions about this item

How does the 0–5 V control voltage translate into the 0–500 V output on this module?

The CTRL input accepts 0–5 V and the output follows linearly from 0 V to 500 V, so the full 5 V signal commands the maximum 500 V.

What input current should I budget from a 12 V source when the module delivers its maximum 20 mA at 500 V?

At full load the unit draws up to 1.2 A from the 12 V rail, while idle or light-load conditions sit near 250 mA.

What physical mounting provision does the metal enclosure of this AHV12V500V20MAW module provide?

The metal enclosure serves as both EMI shielding and a heat-sinking surface, allowing direct chassis mounting for thermal transfer.
