SP-18000 : 18,000W AC to DC Adjustable Switching Power Supply With PFC
The WEHO SP-18000 is an absolute powerhouse engineered for extreme industrial environments, delivering a staggering 18,000W of single-output power from a single unit. Utilizing an adaptive wide-input architecture, it operates at 50% capacity on 95-190VAC inputs and reaches a full 100% load on 195-265VDC inputs. This flagship model offers a versatile range of DC output specifications, including 30V, 36V, 48V, 60V, and 110V configurations. Beyond raw power, it achieves full-scale linear control, allowing both voltage and constant current to be adjusted smoothly from zero up to their absolute peaks (e.g., pushing up to 480A on the 30V model). Acting as a master energy hub, the SP-18000 deeply integrates an RS485 Modbus interface, an isolated 12V/0.5A auxiliary power supply, and a dry-contact “Power Good” alarm signal.

Application Fields & Advantages
Core Competitive Advantages
Ultimate Single-Unit Density: By outputting 18kW from one module, it directly replaces the need for massive, redundant cabinets filled with parallel-connected lower-wattage units. This entirely eliminates the risk of current-sharing imbalances and frees up critical physical space in OEM control rooms.
Infinite Linear Tuning: Breaking the mold of static converters, it allows operators to fine-tune both the output voltage and constant current thresholds from true zero up to maximum capacity. This transforms the unit from a mere power supply into a highly precise, programmable industrial test source.
Extreme Shock Resistance: Designed with highly resilient protection logic, the unit can seamlessly transition into a constant current mode during instantaneous overloads or short circuits. This enables it to safely absorb the violent startup surges of heavy induction motors or massive capacitor banks without triggering catastrophic system blackouts.
Digital Telemetry Ecosystem: Armed with native RS485 Modbus communication, customizable high-level remote switching, and dry-contact feedback, it allows facility managers to execute millisecond-level monitoring and enable “lights-out” automated control.
Primary Application Fields
Energy Storage & EV Infrastructure: The massive 18,000W capacity and intelligent telemetry make it the ultimate master power gateway for commercial electric vehicle (EV) supercharging hubs and megawatt-class battery charging and discharging arrays.
Heavy Electrochemical Processing: Leveraging its extreme current output—up to an immense 480A—it perfectly serves high-intensity continuous production lines such as industrial hard anodizing, large-scale hydrogen water electrolysis, and heavy-duty metal plating.
Heavy Machinery & High-End Equipment: Provides a shock-resistant, ultra-pure DC power backbone for large CNC machining centers, industrial plasma cutting matrixes, and heavy robotic assembly networks.
