Medium Capacity Electrolyser power supply for PEMProduct parameters :
HRP0X00PLow Voltage & High Current Output: Delivers 5,000–8,000A current with a voltage range of 200–800Vdc, fully optimized for PEM electrolysers’ low-voltage, high-current-density operation.
Ultra-Low Ripple Control: ≤1% current ripple minimizes polarization losses, enhancing electrolyser efficiency and longevity.
3-Level IGBT + Interleaved BUCK Topology: Achieves ≥97% peak efficiency, significantly reducing energy costs.
Grid-Side Power Factor: ≥0.99 with ≤3% current harmonic distortion, meeting stringent grid integration standards.
100ms Rapid Response: Adjusts power/current curves in real-time, seamlessly syncing with renewable energy fluctuations for off-grid/microgrid applications.
Smart Liquid Cooling System: IP54-rated protection ensures stable operation in extreme environments (-35°C to +60°C), extending lifespan by 30%.
Multi-Mode Control: Supports constant current, voltage, or power modes for complex PEM operational requirements.
Process Interlocks: Deep integration with Balance of Plant (BOP) systems for real-time electrolyser monitoring and safety assurance.
Fault Recording & Diagnostics: Millisecond-level anomaly detection and root-cause analysis improve maintenance efficiency by 50%.
