| Core Upgrade: AFV-P Series New Generation, Redefining the Experience with "Powerful Performance + Lightweight Design" |
| To meet the testing needs of R&D and quality assurance across multiple scenarios, the new-upgdrade AFV-P programmable AC power source is 50% lighter, making it more portable and easier to handle. It features a new active PFC (Power Factor Correction), reducing apparent power by approximately 32.7%, saving energy while ensuring stable power output. With an expanded voltage range of 0–350V and power output from 800VA to 6kVA, it aligns with IEC standard testing requirements and supports a wide range of applications, including industrial equipment and explosion-proof lighting—delivering full-strength performance! |
| Targeting Industry Demands, Empowering Multiple Fields with Technology |
| The upgraded AFV-P series complements products such as Programmable DC Power Supply ADG-L and ADG+ lines, collaboratively powering implementations in multiple fields. By addressing the key testing challenges of various industries, we have introduced targeted solutions to achieve seamless integration of technology into practical solutions. |
| ? Smart Appliance Testing: Single Unit Compatible with Global Power Grids, Enabling Efficient and Seamless Dual-Standard Compliance. |
| As the smart home market continues to expand, the quality and safety of smart appliances are receiving increasing attention. Rigorous and standardized testing has become essential to ensuring product reliability. The AFV-P programmable AC power source features a wide output voltage range of 0–350 V and an adjustable frequency range of 5–2000 Hz, making it fully compatible with GB/T 4706.1-2024 and the IEC 60335 series standards. With low distortion, versatile communication options, and the ability to complete multiple tests in a single run, it helps companies reduce costs and risks while ensuring high-efficiency compliance and product safety. |
| ? EMC Certification Testing: Accurately Managing Harmonics and Flicker to Ensure Smooth, Hassle-Free Compliance |
| Leveraging the AFV-P programmable AC power supply’s low-distortion waveform output (≤0.3%) and precise power disturbance simulation function, it complies with standards such as IEC61000-3-2 and IEC61000-3-3. It is suitable for harmonic and voltage flicker tests in EMC certification, meeting the testing needs of equipment across diverse industries, and helping products efficiently pass EMC certification for rapid market launch. |
| ? Industrial Fan Testing: Overcoming Harmonics and Inrush Currents to Meet Multi-Standard Verification. |
| Comprehensive fan performance testing—covering airflow, pressure, efficiency, and more—when using traditional power sources is often affected by issues such as harmonic interference, startup inrush, and data distortion. The AFV series high-power programmable AC power supplies deliver a precise solution with ≤1% low-distortion clean output, soft-start current stabilization, and ramp mode simulation to handle complex test scenarios. Aligned with multiple national standards, they offer an all-in-one approach to ensure compliant and highly accurate fan testing, helping users efficiently complete performance verification. |
| ? AI Server Testing: High-power and Fully Programmable Solutions Designed for the Next-Generation Voltage Requirements. |
| In the AI era, AI servers must handle extremely high computational demands, driving power architectures toward higher voltage levels. While 48V DC is currently the mainstream for chassis power, 54V and 400V solutions are gradually being adopted, and the future of 800V architectures will be essential to support increasing power consumption. The ADG-L programmable DC power supply meets present testing requirements, while the high-power ADG+ programmable DC power supply can support future 800V and 1.8 MW-level power needs, offering advantages such as high-power capacity, full programmability, and safety compliance features. |
| ? Electric Vehicle PTC Testing: Supporting High-Voltage and Large-Scale Testing to Handle the Harshest Scenarios |
| Amid the surge of electric vehicles, the demand for PTC heater performance testing has intensified, with high voltage, multi-unit synchronization, and precise stability becoming key requirements. The ADG+ series high-power DC power supply provides an accurate solution: supporting ≥800V high voltage, three-unit synchronized testing, with 300 kW output power in a single unit and ultra-high 2000V voltage. It delivers low ripple (≤0.05%), high accuracy (≤0.1%), and background noise as low as 0.2%. Equipped with multiple protections and dedicated software, it adapts to various testing scenarios while remaining easy to operate, making PTC heater testing both efficient and reliable. |
| 2026 Vision: Relentless Innovation, Fueling the Next Wave of Industrial Transformation |
| In 2026, Preen will continue to focus on upgrading its core products, keeping pace with industry trends, and expanding into more application scenarios. At the same time, it will deepen global market partnerships, providing superior power solutions to support the growth of customers worldwide and jointly create new value for the industry. |
