Precision instrumentation designed for BMS validation, electrochemical lab analysis, and high-power industrial battery emulation.
Why traditional voltage-fed switch-mode power supplies fail under extreme Australian grid transients—and how magnetic inductive bus storage delivers bulletproof endurance.
Traditional voltage-fed programmable power supplies rely heavily on massive electrolytic output capacitor banks to smooth output voltage ripples. When subject to fast load changes, regenerative kickback from traction motors, or short circuits, these capacitors experience massive current surges, leading to premature dielectric breakdown—a frequent issue in mining sites across WA and QLD.
Our proprietary Current-Fed Topology substitutes high-capacity bus capacitors with robust input inductors. The inductor acts as an inherent current limiter, storing energy magnetically rather than electrostatically. In the event of an output short circuit or explosive dynamic discharge, the peak current rise is physically constrained by inductance, rendering the power supply completely immune to dead-shorts.
Australia’s National Electricity Market (NEM) operates under nominal 400V/415V 3-phase AC mains at 50Hz, often exhibiting significant voltage fluctuations in remote regional substations (e.g., Pilbara mine sites or regional solar farms). Our export systems incorporate active power factor correction (PFC > 0.99) and universal wide-input range transformers (380V - 480V AC 3-phase, 50/60Hz).
Furthermore, operating test equipment in interior Australia requires surviving ambient temperatures exceeding 45°C. Our thermal design integrates conservative MOSFET silicone junction rating margins, dual-stage variable-speed cooling fans, and optional closed-loop liquid-cooled heat exchangers (ML Series) to deliver 100% continuous duty rating without thermal derating.

From remote Western Australian mining pits to high-tech defense corridors in South Australia, explore how our programmable DC solutions solve complex engineering challenges.
Australian iron ore giants are transitioning haulage fleets from diesel to ultra-high-capacity battery electric vehicles (BEVs). Testing 800V to 1200V battery packs and dynamic regenerative braking systems requires bi-directional capabilities and high power density. Combining MagnaDC programmable power supplies with MagnaLOAD electronic loads allows engineers to simulate exact uphill haul power draw and dynamic downhill charging curves.
Australia boasts the world's highest per-capita rooftop solar and massive utility PV installations across Queensland and NSW. Inverter compliance under AS/NZS 4777.2 requires rigorous maximum power point tracking (MPPT) testing under rapid cloud-cover irradiance transients. Utilizing our Photovoltaic Power Profile Emulation (PPPE) software, MagnaDC supplies emulate 1500V DC solar array I-V curves with high accuracy and low ripple.
PEM and Alkaline hydrogen production plants demand continuous high-current DC power with minimal Total Harmonic Distortion (THD) to maximize membrane longevity. Our water-cooled ML Series delivers up to 24,000A DC with current-fed power conversion, protecting delicate electrolyser cell stacks against instantaneous over-current spikes and thermal runaways during grid-coupled renewable power fluctuations.
Defense science facilities require low-noise, highly reliable DC power sources to simulate submarine main propulsion battery banks, sonar arrays, and high-frequency radar transmitters. The integrated DBx High-Stability module reduces current drift to under 5 ppm/°C, while full LXI Class C Ethernet compliance enables seamless isolation within secure ATE hardware-in-the-loop (HIL) simulation racks.
Key insights for Australian procurement managers, electrical system integrators, and university researchers.
With coal-fired power plants retiring earlier than forecasted across the National Electricity Market (NEM), battery energy storage systems (BESS) are essential for grid frequency control (FCAS). Testing megawatt-scale battery racks and string inverters demands robust, scalable DC sources that can replicate fast discharge rates without overheating.
Australia produces over half the world’s lithium, alongside massive reserves of nickel and cobalt. Federal policy is actively moving from raw mineral export to domestic refining and precursor battery material manufacturing. This shift requires industrial-grade DC power supplies for electrowinning, electro-refining, and automated cell formation lines.
The adoption of Silicon Carbide (SiC) and Gallium Nitride (GaN) power electronics in Australian EV traction drives requires test systems capable of handling extremely high switching frequencies (dV/dt > 100 kV/µs). Magna-Power’s high slew rate options and low bus inductance allow accurate double-pulse testing without ringing distortion.
