Magna-Power Electronics has expanded its SLx Series programmable DC power supplies with new high-voltage 1U models rated at 2000 Vdc, 2500 Vdc, and 3000 Vdc. The company says the new units deliver up to 3000 Vdc and 10 kW in a standard 1U rack-mount enclosure (1.75″ x 19″ x 24″) with fully floating outputs.
The new high-voltage models are offered across six power levels from 1.5 kW to 10 kW. Magna-Power positions the launch as an extension of the SLx Series platform introduced in 2023, pushing beyond the original product line’s 1000 Vdc ceiling. With these additions, Magna-Power says the SLx Series now spans 5 Vdc to 3000 Vdc and up to 250 Adc, covering 171 models and over 60,000 configurations. Output isolation is standard across the SLx Series, supporting floating operation at full rated voltage.
Magna-Power lists target applications including double pulse testing for SiC and GaN wide bandgap semiconductors, high-voltage power converter testing, capacitor charging and forming, high-voltage DC cable testing, and power delivery for tethered vehicles, including ROVs.
On the power stage and control side, Magna-Power says the SLx Series uses a current-fed power processing topology with SiC power devices, aiming for inherent fault current limiting and surge immunity. The xGen MagnaLINK distributed DSP digital control architecture provides 16-bit programming resolution for voltage, current, and power, with programmable slew rates on all three parameters. Published regulation and stability figures include ±0.04% line regulation for voltage, and ±0.005% (100 ppm) 8-hour voltage stability at 25° C.
For integration, every SLx Series model includes dual USB ports (front and rear), RS485, and SCPI and Modbus command sets with over 60 documented commands. A 26-pin D-Sub connector provides eight digital outputs, four digital inputs, four analog outputs, four analog inputs, and a dedicated high-speed 2 kHz analog input. Optional industrial communications include EtherCAT, EtherNet/IP, PROFINET, CANopen, LXI TCP/IP Ethernet, and Modbus-TCP, each with full command-set support and device description files. MagnaCTRL software is included, with LabVIEW and IVI drivers available.
Magna-Power also describes a parallel scaling option: up to 16 SLx Series units can be connected in parallel via its digital-hybrid master-slaving architecture using dual MagnaLINK communication ports, allowing a single setpoint to coordinate output and protections across the group. Safety and serviceability features listed include hardware emergency stop, programmable over-voltage, over-current, and over-power trips, and a rear-mounted LED diagnostic matrix intended for field troubleshooting without opening the enclosure.
Configuration options for the high-voltage models include the +WC sealed water-cooling enclosure for ventless operation, the +RUG ruggedized option tested to select MIL-STD-810G and RTCA DO-160 shock and vibration specifications, and the +FP1 blank front panel for system integration. Input power is specified as three-phase AC from 208 Vac to 480 Vac, 50-60 Hz, with single-phase active PFC input also available on the 1.5 kW and 2.6 kW models. Magna-Power states the SLx Series is CE, UKCA, and RCM marked, RoHS and REACH compliant, and certified to EN61010-1.
The company says the new high-voltage SLx Series models are designed and manufactured at its 73,500 sq-ft facility in Flemington, New Jersey, and that every unit is fully tested, calibrated, and burned in before shipment. Magna-Power says the models are available now with build times of 4-6 weeks, sold direct or through its distribution network in over 40 countries.
