Key features

Non-Linear Load Simulation: Replicates rectifier-based loads using R, C, D modules to match real-world grid distortion.

High-Precision Adjustment: Offers fine-resolution load regulation with 0.01kW step for resistive/capacitive components.

Wide Voltage Compatibility: Supports single-phase (120V/220V) and three-phase (380V/400V/690V) inputs with 50Hz/60Hz.

Unbalanced Load Control: Adjusts each phase separately to simulate unbalanced conditions and test DUT stability.

Dynamic Transient Simulation: Enables rapid load switching in milliseconds to verify dynamic response of generators and UPS.

Multi-Protocol Communication: Integrates RS485, Ethernet, and USB for remote control and automated test system integration.

Comprehensive Protection: Includes over-temperature, over-current, over-voltage, short-circuit, and reverse-polarity protection.

AI-Powered supplier vetting

SummaryVILVA demonstrates R&D, customization, ODM, OEM, quality-control, and production capabilities. It reports new products within the past year, 12 years of R&D engineer experience, two production lines, and procedures for service capability, corrective actions, complaints, traceability, and quality assurance. The supplier holds or reports ISO9001:2015, CE, CQC, CCC, national high-tech enterprise, specialized-innovative enterprise, and innovative enterprise certifications. However, it reports no overseas warehouse, showroom, agent, or branch, and no SDK availability. Financial information is recorded as zero for the stated periods, so financial credibility cannot be positively established from the supplied data. Customer-specific cases are not identified, although the supplier states it provides OEM services for well-known brands.

Supplier typeThe supplier presents itself as an integrated R&D, production, and sales enterprise, with ODM services, OEM services for well-known brands, and two production lines. Its operating model and service offerings are explicitly described, supporting classification as a manufacturer with R&D and OEM/ODM capabilities.

CertificationsThe supplier reports ISO9001:2015 quality management system certification, CE, CQC, CCC, and several enterprise-status certifications. However, supplier management system certification is separately listed as NIL, so the positive assessment is limited to the certifications explicitly reported.

After-Sales capabilityThe supplier has documented procedures and records for service capability, corrective and preventive actions, and customer complaints, along with quality assurance, traceability, and maintained quality-control instructions. It lacks overseas warehouses, showrooms, agents, and branches, which limits demonstrated overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year, customization and ODM capability, 12 years of total R&D engineer experience, and an integrated R&D and production model. It does not have an available SDK, but the reported product-development and R&D evidence supports a positive assessment overall.

Production capacityThe supplier operates two production lines and describes a production base within an industrial park with an integrated industrial-chain model. It also reports average lead times within 15 workdays to one month in both off-season and peak-season fields, but the available information does not quantify capacity or output.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service availability, directly supporting broad customization capability.
