Select from our standard CE-certified dynamic loads, bi-directional simulators, and multi-channel BMS testing platforms engineered for global export.
In the modern power electronics ecosystem, dynamic electronic loads and battery cell simulators are no longer passive energy sinks. They serve as mission-critical hardware-in-the-loop (HIL) validation instruments across automotive electrification, aerospace microgrids, renewable energy storage, and semiconductor test bays.
Global export compliance demands adherence to European safety and electromagnetic standards. Our dynamic loads undergo rigorous testing under IEC/EN 61010-1 (Safety requirements for electrical equipment for measurement, control, and laboratory use) and IEC/EN 61000-6-2 / 61000-6-4 for heavy industrial electromagnetic compatibility (EMC).
This guarantees that fast dynamic load switching—exceeding $di/dt$ slew rates of 10 A/µs—does not inject destructive conductive interference back into the main AC grid or distort nearby measurement transducers.
Unlike standard switch-mode electronic loads that rely heavily on large capacitive banks across the input terminals, our industrial-tier dynamic load instruments leverage advanced Current-Fed Topologies.
By storing energy inductively on the internal DC bus rather than capacitively, current-fed conversion delivers natural short-circuit immunity, extreme tolerance against severe voltage spikes, and instant transient recovery when testing wide-bandgap (SiC and GaN) power switches under aggressive duty cycles.
Modern battery management systems (BMS) and DC-DC converters experience rapid load steps during real-world acceleration or pulse-power operation. Our programmable dynamic loads feature microsecond response times with zero output overshoot.
Engineers can program complex arbitrary profiles, simulating pulse loads, internal resistance (IR) variations, and real-time state-of-charge (SOC) decay with high-fidelity 16-bit DAC control.
Choosing the proper dynamic load or battery cell simulator depends on operational voltage windows, peak dynamic slew rates ($di/dt$), power envelope demands, and thermal rejection environment.

When measuring delicate sensor feedback or low-noise ripple on DC buses, standard PWM switch-mode loads introduce EMI artifacts that skew test results. Linear MOSFET dynamic loads sink current by controlling the gate voltage of power transistors operating in their linear active region.
This yields clean current waveforms with negligible high-frequency switching noise—essential for characterizing micro-ampere standby currents or performing broadband electrochemical impedance spectroscopy (EIS).
Simulating a 800V EV pack requires precise voltage control down to individual series-connected cells. Traditional power supplies cannot safely stack high-voltage floating outputs due to isolation breakdown.
Our 24-channel battery cell simulators feature channel-to-channel galvanically isolated power supplies capable of floating up to 1000V DC. Each channel independently emulates cell voltage, internal resistance, and balancing currents, delivering authentic Hardware-in-the-Loop (HIL) conditions for BMS controllers.
As global industries accelerate electrification and transition toward high-voltage DC architectures, procurement teams must align equipment specifications with emerging technical imperatives.
Commercial electric vehicles, utility-scale battery energy storage systems (BESS), and solar inverters are rapidly shifting from 400V/800V up to 1500V DC topologies to minimize copper losses and elevate system efficiency.
Future-proof procurement strategies mandate dynamic electronic loads rated for continuous 1500V operation with wide constant-power envelopes, enabling single-instrument coverage across broad voltage/current curves.
Silicon Carbide (SiC) and Gallium Nitride (GaN) power devices operate at switching speeds ten times faster than legacy IGBTs. This requires dynamic loads capable of sinking high peak current steps within microsecond windows without inductive voltage ringing.
Advanced dynamic loads incorporate ultra-low parasitic inductance internal busbars and fast analog control loops to mirror SiC converter dynamics accurately.
Smart factories rely on automated test equipment (ATE) controlled remotely via standardized command interfaces. Modern dynamic loads integrate native Ethernet/LXI, USB, RS-232, and optional Modbus TCP or IEEE-488 GPIB interfaces.
Comprehensive Python, LabVIEW, and IVI driver support empowers engineering teams to integrate dynamic load hardware seamlessly into digital twin simulation pipelines and automated factory calibration racks.
From initial circuit design to full-load burn-in testing, our vertically integrated manufacturing ensures unparalleled quality control, compliance traceability, and global export reliability.
