The hydrogen power supply series comprises ACDC and DCDC IGBT models, both featuring water cooling, a wide regulation range of 10%–110%, and parallel operation capability. The ACDC variant suits largescale centralized windsolar electrolysis (200–5000 Nm³/h), while the DCDC variant is tailored for distributed offgrid PV applications (200–1000 Nm³/h). Backed by our integrated R&D, manufacturing, sales, and service, we ensure reliable performance across diverse hydrogen production scenarios.
