DC power supplies from 1.5 kW to 10 MW and linear MOSFET electronic loads to 20 kW+ — built on a rugged current-fed topology.
Every figure below reflects work completed inside one vertically integrated facility — from magnetics winding to final full-load burn-in.
Firmware, SCPI command sets, user I/O and option codes are held consistent across families. Move from a 1U bench unit to a megawatt cabinet without rewriting your test sequences.
MagnaDC uses a current-fed power processing topology in which an inductor, rather than a capacitor, stores energy on the DC bus. The result is inherent short-circuit tolerance, graceful behaviour into reactive and regenerative loads, and full-power operation across a wide voltage window instead of a single nominal point.
MagnaLOAD ALx models sink power through a linear MOSFET stage governed by the MagnaLINK™ distributed DSP platform. Linear operation means no switching noise injected back into the device under test — critical when characterising fuel cells, battery packs, converters or PV strings where measurement fidelity matters.
Start from available rack space, cooling method and required output power. Each series shares the same programming interface, so the choice is mechanical and thermal rather than software.
| Series | Power range | Form factor | Cooling | Best suited to |
|---|---|---|---|---|
| SLx | 1.5 – 10 kW | 1U rack-mount | Air | xGen bench and ATE racks, double pulse DC bus supply |
| SL | 1.5 – 10 kW | 1U rack-mount | Air | Space-constrained production test stations |
| XR | 2 – 10 kW | 2U rack-mount | Air | Higher voltage ranges with generous derating margin |
| TS | 5 – 100 kW | 3U – 16U rack-mount | Air | EV, magnet and electrolysis test benches |
| MT | 150 kW – 3 MW | Cabinet | Air | Wind tunnels, radar, plasma and industrial process power |
| ML | 500 kW – 10 MW | Cabinet | Water | Continuous megawatt duty where heat rejection is limited |
| ALx | 1.25 – 20 kW | Rack-mount | Air | Battery, fuel cell, PV and converter load characterisation |
Higher power is reached by paralleling units under a single master controller; consult the series pages for voltage and current matrices.
Design control, in-house manufacturing and long product lifecycles are what let procurement teams standardise on Magna-Power for a decade or more.
Command sets, protection logic, option codes and analog I/O pinouts remain aligned across families, so validated test software carries forward as power requirements grow.
Ethernet/LXI, USB, RS-232 and isolated analog I/O are standard, with optional IEEE-488 and Modbus TCP. Drive units by SCPI, supplied NI LabVIEW and IVI drivers, or Python.
Stocked common assemblies and in-house machining, magnetics and PCB assembly support 4–6 week made-to-order builds, with selected models available from ready-to-ship inventory.
Tailor performance with high slew rate output, integrated blocking diode, water cooling, and the DBx high-stability module for low-drift magnet and metrology work.
Magna-Power designs and builds its instruments at its headquarters in Flemington, New Jersey. Engineering sits beside the production floor, which shortens the feedback loop between a field observation and a released design improvement.
The same instrument family supports laboratories, defence programmes and high-volume production lines. These are the workloads our applications engineers see most often.
Stiff, low-ripple high voltage DC bus supplies for double pulse testing of SiC and GaN switches, with blocking diode options to protect against inductive kickback.
Traction inverter, on-board charger and pack-level validation, pairing programmable supplies with linear MOSFET loads for bidirectional cycling profiles.
High-stability current regulation with the DBx module for dipole, quadrupole and steering magnet supplies where drift budgets are measured in parts per million.
Megawatt-class air and water-cooled systems delivering sustained arc-heater power with coordinated master/slave current sharing.
PPPE software drives I-V curve, irradiance and temperature sweeps so inverter maximum power point tracking can be characterised repeatably.
Rugged current-fed conversion tolerates arcing, short circuits and highly dynamic loads typical of pulsed RF, coating and electrolysis systems.
From two-person startups to Fortune 500 primes, aerospace laboratories and research universities on six continents.
Inductive DC bus energy storage limits fault current naturally, giving short-circuit and arc tolerance without sacrificing regulation.
Full rated power is available across a broad voltage and current window, so one model often replaces several fixed-point supplies.
Programmable over-voltage and over-current trips, thermal and interlock monitoring, and documented fault reporting over the digital bus.
Factory repair in New Jersey backed by regional service centres for the EU, UK, Australia, New Zealand, China and Taiwan.
“To do what Magna-Power does with one power supply, we would have needed three from the other guys. On top of that, Magna-Power was less expensive, so the bang for buck and size was excellent.”Paul K.Lockheed Martin
“Below is the scope capture from the XR connected directly in place of the previous supply. We were amazed. I am impressed with the build quality of the unit — chalk one up for Made in the USA.”Tom S.QinetiQ
“High quality products from Magna-Power. I have worked with other manufacturers and faced different problems such as EMI noise, but no problem with Magna-Power.”Amin S.University of Houston
“Beyond being a vendor of great products we use every day, we look up to Magna-Power as the gold standard of a domestic power electronics manufacturer.”Hanan F.Alencon Systems
“All my questions were answered thoughtfully and we had full confidence in our purchase. The power supply has been handling every load we throw at it without so much as a hiccup.”Adam S.Blue Robotics
“I have two Magna-Power supplies in my lab. I love them: reliable, precise, wonderful equipment.”Marcelo S.Colorado School of Mines
