Dual‑Output MAO Test Rectifier | 30A‑800V /15A‑300V

Built for diverse laboratory‑based micro‑arc oxidation research, this dual‑output MAO test rectifier delivers two distinct adjustable power ranges to process varied aluminium, titanium and magnesium alloy test workpieces without switching equipment.

    Product Introduction

    Dual‑Output MAO Test Rectifier meets the practical demands of material laboratories running multiple sets of micro‑arc oxidation experiments with different power requirements. In fact, research teams often alternate between high‑voltage low‑medium‑current modes and moderate‑voltage low‑current modes to observe how power parameters influence ceramic coating formation. Even so, deploying two separate rectifier units raises procurement costs and occupies precious bench‑top workspace; accordingly, lab layout planning and multi‑group sample testing efficiency become restricted.

    Rated for dual output specifications 30A 800V and 15A 300V, this dual‑output MAO test rectifier adopts flexible‑range IGBT conversion architecture optimised for multi‑mode MAO lab workflows. Operators can switch between the two power ranges and fine‑tune pulse frequency as well as duty cycle through local control panel to match diverse alloy substrates and target coating indicators. Once lab staff finish wiring and electrolytic cell assembly, researchers can shift test conditions rapidly with no extra hardware rewiring when processing different specimen batches. Meanwhile, integrated arc‑suppression paired with multi‑layer safety protection reacts swiftly to intense spark surges, and this protective feature shields test coupons and internal circuit hardware during frequent mode‑change experimental cycles.

    Core Selling Points for Dual‑Output MAO Test Rectifier

    • Equipped with two adjustable output ranges: 0‑30A 0‑800V and 0‑15A 0‑300V, supporting flexible multi‑condition micro‑arc oxidation lab specimen processing
    • Fast internal range switching avoids tedious cable reconnection when shifting between high‑voltage and medium‑voltage experimental groups
    • Freely tunable pulse frequency and duty‑cycle parameters adapt to varied lightweight‑alloy sample evaluation and coating‑exploration tasks
    • Built‑in arc‑suppression assembly suppresses violent spark discharge, minimising thermal ablation damage to delicate alloy test pieces
    • Air‑cooled fan‑driven design requires no external cooling‑water piping, simplifying installation on standard laboratory workbenches
    • Dual closed‑loop voltage and current control offsets electrolyte impedance fluctuation, enhancing data consistency across multi‑range test sequences
    • Comprehensive protection includes over‑voltage, over‑current, over‑temperature and short‑circuit alarm to guarantee stable long‑term lab‑site operation
    • Supports local panel operation and RS485 Modbus RTU connection for experimental‑data logging, multi‑range parameter storage and complete test‑run traceability

    Product Advantages of Dual‑Output MAO Test Rectifier

    This dual‑output MAO test rectifier adopts high‑adaptability IGBT pulse conversion hardware, and operational efficiency stays above 86% under alternating‑range laboratory test load. Unlike single‑specification rectifier devices, this integrated unit combines two independent working windows within one cabinet; hence, research labs cut equipment investment and save limited bench‑top space.

    Fast‑response closed‑loop feedback compensates subtle electrolyte impedance shifts as ceramic oxide coatings gradually build up on alloy sample surfaces. As a result, test coupons sustain fewer burn‑caused defects under both output ranges, and R&D teams obtain reliable comparative data for cross‑parameter MAO formula research. What is more, onboard memory stores multiple parameter presets for each working range, and operators can load validated test profiles instantly instead of manually adjusting settings for every new test batch.

    Optimised for frequent‑range‑switch MAO laboratory environments, internal power circuits strictly control output ripple across both power outputs. Therefore, it delivers stable pulse energy to generate hard, wear‑resistant ceramic protective layers for various aluminium, titanium and magnesium alloy test components.
