SP-15000 : 15000W AC to DC Adjustable Switching Power Supply With PFC

The WEHO SP-15000 is an ultra-high-capacity single-output switching power supply engineered for heavy industry and smart manufacturing, delivering a colossal 15,000W of continuous power. Featuring an adaptive wide-voltage input design (95-190VAC at 50% load / 195-265VAC at 100% load), it provides a versatile lineup of DC output configurations from 30V up to 220V. As a true industrial-grade smart power supply, it supports smooth, linear adjustment of both voltage and constant current from absolute zero to peak, achieving an outstanding energy conversion efficiency of up to 93%. Housed in an ultra-high-density chassis, the SP-15000 deeply integrates the RS485 Modbus communication protocol, an isolated 12V/0.5A auxiliary power supply, and a dry-contact alarm (Power Good) interface, serving as an all-in-one energy hub for complex automated systems.

Input voltage: 95-190VAC(output current 50%)195-265VAC(output current 100%)

Differentiated Advantages

The SP-15000 completely disrupts the traditional high-wattage power market, utilizing its extreme density and smart IoT integration to replace legacy systems:

Extreme Power Density (Cabinet Replacement): Traditionally, achieving 15kW required purchasing bulky, parallel-connected multi-unit cabinets. The SP-15000 leverages an advanced topological architecture to condense 15,000W of immense power into a single ultra-high-density module. This not only saves invaluable control cabinet space for OEM clients but also completely eliminates the complex wiring costs and current-sharing failure risks associated with multi-unit arrays.

Full-Scale Absolute Zero Tuning: Unlike standard industrial power supplies limited to narrow ±5% fine-tuning, the SP-15000 grants engineers absolute control. Both output voltage and constant current thresholds support ultra-wide, smooth linear adjustment starting from true zero. This unprecedented dynamic range allows it to effortlessly handle highly demanding applications like large-capacity battery formation, heavy-duty electrolysis, and extreme high-voltage aging tests.

Native “Industry 4.0” Integration: Abandoning the traditional “black box” isolated power approach, the SP-15000 acts as an active digital node. Powered by its native RS485 Modbus protocol, it seamlessly integrates into SCADA and advanced PLC central control systems. Paired with customizable dry-contact alarm feedback and high-level remote shutdown capabilities, facility centers can monitor underlying power health in milliseconds, enabling true digital energy management for “lights-out” unmanned factories.

Shock-Resistant Smart Fault Defense: When facing instantaneous startup surges from heavy machinery—such as massive induction motors or giant capacitor banks—the SP-15000 exhibits exceptional resilience. During momentary over-current events, the power supply intelligently transitions into constant current mode to absorb the surge, rather than triggering a catastrophic system blackout like lower-end units. This drastically maximizes the uptime and operational continuity of your multi-million-dollar production lines.
