WEHO SP-3000 Series: 3000W Smart Programmable DC Power Supply with RS485 Communication & Parallel Scaling

The WEHO SP-3000 is an ultra-compact, intelligent single-output switching power supply engineered to deliver a robust 3000W of precision power. It features an adaptive wide-input design, operating on 95-190VAC (at 50% load) and 195-265VAC/VDC (at 100% load). Available in diverse DC output configurations from 12V up to 220V , this high-density module achieves an outstanding peak energy efficiency of 93%. Designed for advanced automated systems, the unit is encased in a highly compact 289 x 174 x 69 mm chassis weighing only 3.3kg. It comes fully equipped with an isolated 12V/0.5A auxiliary power supply, a default-on remote control switch, and a dry-contact “Power Good” alarm signal.

Product Competitive Advantages

The SP-3000 breaks the boundaries of traditional power conversion, offering elite-tier integration features for complex OEM ecosystems:

RS485 Bus & Seamless Parallel Expansion: This unit stands out with its built-in RS485 communication protocol and integrated parallel current sharing technology. It can directly communicate with central PLC networks for real-time monitoring, and allows operators to infinitely scale their power grid by safely daisy-chaining multiple units together.

Intelligent Fault Tolerance & Delay Logic: Instead of hard-crashing during an overload, the SP-3000 allows engineers to program a custom 5-second over-current delay. This uniquely absorbs the massive startup surge currents of heavy motors or capacitive loads without triggering unnecessary system shutdowns, vastly improving factory uptime.

Ultra-Wide Linear Adjustability: It provides exceptional, surgical control over your power delivery. Both the output voltage and constant current can be dialed in from near-zero to their absolute maximums (e.g., 0-242V tuning on the 220V model). This makes it a flawless primary source for delicate electrochemical processing, EV battery forming, and high-stress component aging tests.

Exceptional Power Density: Achieving 3000W in a 3.3kg, ultra-slim profile is an engineering feat. Combined with its built-in auxiliary power and alarm relays, it eliminates the need for third-party control modules, saving crucial physical space and wiring costs inside crowded industrial control cabinets.
