Purpose-Built HV Module

The AHV12V500V50MAW is a linear DC-DC converter that steps a 12 V supply up to an adjustable 0-500 V rail at up to 50 mA. It targets engineers integrating high-voltage bias into X-ray, spectroscopy, semiconductor or electrospinning equipment where precise, low-noise output is mandatory.

Integration Footprint

The unit accepts 12 V ± 1 V drawing 700 mA to 3 A and is governed by a 0-5 V control signal, with an optional electronic shutdown pin for system-level sequencing. A 5 V ± 0.05 V reference is provided on-board, and the metal enclosure doubles as a heatsink, eliminating the need for external EMI filtering or bulky forced-air cooling in the host chassis.

Sustained-Load Behaviour

Linear regulation topology guarantees zero switching artefacts across the full 0-500 V range, so sensitive detectors see a clean supply during long acquisitions. The rugged enclosure maintains thermal equilibrium without derating the 50 mA rating, and the shutdown control allows safe power-down without voltage overshoot that could stress downstream loads.

Questions about this item

What sustained output current can the module deliver at 500 V?

The module is rated for a maximum continuous output of 50 mA at 500 V.

How much heat or noise should I expect when the unit runs continuously at full load?

The metal enclosure provides heat sinking with zero EMI and no fan, so operation is silent and thermal load stays within the case.

What external control voltage source is required to set the output?

A 0–5 V control signal is needed; the module also supplies a 5 V ± 0.05 V reference that can be used for this purpose.
