Project Background
Multiple projects have been implemented at world‑class production benchmark lines of Fortune 500 enterprises. With the rapid growth of AI computing centres, high‑power PSUs (ranging from 3500W to 18000W/27000W) and BBUs (4200W to 8500W) are required to withstand prolonged full‑load burn‑in testing to ensure stable power delivery and backup reliability in data centres. Traditional manual testing methods are unable to effectively address the wide‑power‑range load requirements and multi‑chamber parallel management, which have become production bottlenecks。
Current manufacturing faces these key challenges:
✅ Manual loading/changeover is slow for high‑power production
✅ Inconsistent testing across power ranges hurts reliability
✅ Heat dissipation and temperature monitoring are complex and lagging
✅ Full‑process data is insufficient, lacking Hi‑pot and Calibration support
The client plans an automated burn‑in line integrating chambers with Hi‑pot, Pre‑ATE, Load Share, and Final‑ATE to boost automation and reliability.
First:Equipment Overview and Core Capabilities
1.Equipment Name / Purpose：Burn‑in test equipment for AI server PSU and BBU products.
2.Core Objectives：To perform burn‑in testing for PSUs (3500W to 18000W/27000W) and BBUs (4200W to 8500W)
3.Operating Mode：Utilises either an RGV (Rail‑Guided Vehicle)‑based storage and handling configuration or manual burn‑in cabinets.
4.Testing Features：Dedicated test trays enable shared usage across multiple power ranges, providing load application, temperature control, and voltage/current monitoring.
Second、Test Specifications and Parameters
1.Dimensions：Automated line: 10m (L) × 3.5m (W) × 2.4m (H).
2.Capacity Configuration：60 units per storage chamber; multiple chambers can be connected in parallel.
3.Environmental Control：Temperature maintained at 55°C ± 3°C.
4.Additional Features：In addition to burn‑in testing, Guanjia also provides Hi‑pot, Calibration, Pre‑ATE, Load Share, and Final‑ATE test equipment.
This equipment serves medium‑ to high‑power PSU/BBU and brick power (IBC) manufacturers. It supports burn‑in for PSUs 3.5–18/27kW and BBUs 4.2–8.5kW with shared‑tray loading, temperature control, and voltage monitoring, plus optional Hi‑pot, calibration, Pre‑ATE, Load Share, and Final‑ATE.
Ideal for:
Server/DC power supply makers (VRM, rack PSUs)
5G and telecom power suppliers
ODM/OEM custom power module designers
EMS providers for multi‑brand PSU/BBU manufacturing
