Switching power supplies play a critical role in power conversion and delivery within industrial automation. HONGPOE converts 110 V, 220 V AC, as well as 200 V, 380 V, and 440 V AC (3-phase) or wide-range DC inputs (280–380 V DC, 440–650 V DC) into stable DC voltage with high precision and low ripple, reliably powering core equipment such as PLCs, sensors, servo drives, industrial robots, and HMIs. Compared with traditional linear power supplies, switching power supplies offer higher efficiency, smaller size, and lower heat generation, and are better suited to harsh industrial environments with severe grid fluctuations, strong vibration, high temperature, and dust. They also feature built-in multiple protections against overvoltage, overcurrent, and short circuits, along with a highly anti-interference design.

July 2024, a company based in Lyon, France, selected HONGPOE switching power supplies for the Abu Dhabi rail transit project, with 380VAC input and 4500W / 72V output. Facing local extreme high temperatures exceeding 65°C, HONGPOE's technical team engaged in in-depth communication with the customer to fully understand the on-site operating conditions. By adopting high-temperature, long-life power components, an enhanced airflow convection cooling design, and reserving sufficient power derating margin, the power supplies were able to deliver stable, full-load operation under sustained high temperatures. This solution not only overcame the challenges of high-temperature application but also ensured reliable power delivery to the core systems of the rail transit project.

In the Montreal Advanced Physics Laboratory project in Canada, the client needed to power a high-power precision device with 36,000 W of highly stable electricity, imposing exceptionally stringent requirements on voltage regulation headroom and continuous load capacity. Rather than adopting a single massive power supply, we innovatively deployed twelve 3,000 W switching power supplies and used the built‑in synchronization signal on each unit to seamlessly parallel them, building a super power system delivering 36,000 W. This solution not only perfectly met the client's power and regulation redundancy needs, but also delivered outstanding performance over the subsequent 60‑day heavy‑load operation with zero momentary interruption, bringing the project to a successful delivery. This practice strongly validates the exceptional current‑sharing capability and absolute reliability of HONGPOE’s multi‑unit parallel solution in top‑tier scientific research scenarios
