Voltmat Power
In modern power electronics, components must be stressed to their physical limits to ensure long-term reliability. An electronic load power supply plays a pivotal role in acting as a programmable load, absorbing current and testing the behavior of DC power sources, batteries, and converters.
As leading manufacturers based in Shanghai, we engineer our systems to handle the demanding requirements of global testing standards. By integrating switching power supply technology with robust control loops, we supply industrial facilities worldwide with tools that support high efficiency (88-90%), precise digital adjustments, and reliable safety profiles.
Protects personnel and sensitive equipment under hazardous high-voltage test setups.
OVP, OCP, and OTP mechanisms protect electronic loads from catastrophic failures.
Filtered switching topologies decrease ripple noise for precision DUT measurement.
Continuously tested over long burn-in durations to guarantee solid load regulation.
Explore our highly-stable switching regulated power products. Engineered for high stability, efficiency, and industrial longevity.
Our manufacturing processes conform to globally recognized regulations. To maintain our CE Certified status, every power unit is evaluated against severe electrical stresses.
When integrating an electronic load power supply into local test benches in Europe, North America, or Asia, regulatory alignment is non-negotiable. Our CE Certified power systems are fully configured to satisfy the requirements of:
1. Low Voltage Directive (LVD) 2014/35/EU: Ensures the device performs safely within typical high-voltage limits (up to 1000V DC output).
2. Electromagnetic Compatibility (EMC) Directive 2014/30/EU: Guarantees that our high-power switching power supplies do not generate disruptive electromagnetic waves and are sufficiently immune to environmental static discharges.
Local Support & Spares: We offer comprehensive technical coordination, detailed circuit block diagrams, and compliance certificates for your engineers. This simplifies the validation process during custom test bay installations.
A look at our 10,000 square meter professional factory with 15 years of specialization in high-power regulated power supplies.
To guarantee a qualification rate of up to 99.9%, we deploy two full rounds of computer and manual testing on every power supply before packing. Below is the step-by-step manufacturing and verification process managed inside our facility:
Operating out of Shanghai gives us logistical and raw material sourcing advantages. With key electrical component clusters located within a 100-mile radius, we can manufacture customized switching electronic loads quickly and cost-effectively.
Our facility provides a comprehensive end-to-end supply chain path:
Long-distance international shipping demands robust, protective packing configurations to prevent internal component fatigue. We utilize:
Reliable power testing architectures designed for demanding operating environments around the world.
Our high-power safety DC switching power supplies (like the 500V-16000W) are designed for cycle testing lithium batteries, electric vehicle battery packs, and backup UPS arrays. The adjustable voltage and current outputs allow for custom discharge and charge cycles.
Electroplating applications demand continuous, stable DC currents. Our multi-input systems supply high output stability, minimizing thickness variations in electroplated finishes under continuous operation.
Allows developers to simulate solar panel and wind turbine dynamics. By pairing DC switching power units with high-voltage programmable electronic loads, developers can test solar microinverters against real-world grid conditions.
The rapid expansion of electric vehicle (EV) ecosystems, fast-charging hubs, and utility-scale energy storage arrays is driving power electronics to operate at higher voltages. Traditional 600V testing thresholds are shifting to 1000V and 1500V topologies.
Regenerative Energy Recovery: Modern electronic loads are transitioning from heat-dissipating resistive systems to regenerative architectures. This design feeds up to 95% of the absorbed testing power back into the local AC grid, reducing utility costs and heat generation.
Silicon Carbide (SiC) Integration: The adoption of SiC MOSFETs allows switching power supplies to operate at higher switching frequencies. This reduces transformer footprints while maintaining efficiency levels above 90%, even when operating at maximum load capacities.
High-voltage, high-capacity switching systems configured for heavy industrial deployment.
Direct technical explanations to support your procurement selection and system deployment.
A standard DC power supply delivers electrical energy to a device under test (DUT). An electronic load behaves in reverse; it acts as a sink, absorbing current and dissipating power. Some configurations, like bi-directional power systems, combine both capabilities in a single unit.
Each of our product topologies undergoes testing under full-load conditions at a certified laboratory. We verify electromagnetic emission levels to satisfy standard industrial guidelines, while performing isolation and dielectric strength tests up to 3000V AC to meet safety regulations.
Yes. Our standard systems offer output options from 12V up to 1000V, but we also design custom current and voltage configurations to match specific testing criteria. For detailed project requirements, please contact our Shanghai engineering division.
Our power supplies include over-voltage protection (OVP), over-current protection (OCP), over-power protection (OPP), and over-temperature protection (OTP). If any threshold is crossed, the output stage is disabled within milliseconds to protect both the supply and the device under test.
