Optimised for bench‑top material research tasks, this 30A 750V air‑cooled single‑pulse MAO power supply outputs accurate single‑pulse energy to form durable ceramic protective films on aluminium, magnesium and titanium alloy test samples inside laboratory environments.
30A 750V Air‑Cooled Single‑Pulse MAO Power Supply addresses high‑voltage pulse power demands for plasma electrolytic oxidation studies, where sharp pulse waveforms directly decide ceramic coating quality and test reproducibility. In fact, ordinary general‑purpose power units cannot generate the steep pulse edges required by MAO plasma reactions, and they tend to build up excess heat during hours‑long continuous test cycles. Since micro‑arc oxidation creates instant high‑voltage plasma discharge, effective air‑cooled thermal management remains essential to keep consistent operating temperature and prevent output shift across different test batches.
Rated for 30A 750V working output, this 30A 750V air‑cooled single‑pulse MAO power supply adopts compact air‑cooled thermal construction with no external water chiller needed, which greatly simplifies deployment on space‑limited lab workbenches. Operators adjust pulse frequency, duty cycle, current and voltage parameters via local control panel to match different alloy substrates and target ceramic coating performance targets. After wiring connection and parameter setup, research teams can run repeated micro‑arc oxidation trials for small‑size alloy specimens. Meanwhile, multi‑level electronic protection reacts quickly against over‑voltage, over‑current and short‑circuit risks, and this protective mechanism protects test samples and internal circuit assemblies throughout long‑time experimental operations.
This 30A 750V air‑cooled single‑pulse MAO power supply adopts high‑speed IGBT switching components, and overall unit efficiency stays above 86% under regular experimental loading. Unlike water‑cooled MAO power supplies that need matched circulating water facilities, its air‑cooled mechanical layout cuts auxiliary hardware investment, so research groups can carry out oxidation tests without complicated site reconstruction.
Fast closed‑loop regulation stabilises single‑pulse output status as ceramic oxide layers grow on alloy surfaces. As a result, treated test pieces show smaller coating thickness deviation and fewer surface defects, and researchers can obtain highly comparable experimental data from separate test groups. Moreover, onboard memory stores multiple groups of process parameter presets, and users can recall verified parameter profiles instantly instead of manual setup for every new test batch.
Optimised for micro‑arc oxidation laboratory‑grade research scenarios, internal control circuits keep pulse‑output fluctuation within a narrow tolerance across full adjustment ranges. Accordingly, it provides stable driving energy to produce uniform, wear‑resistant ceramic coatings for diverse small‑format alloy test workpieces.
