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.

Cortocircuito When the constant current is entered and the voltage is lower than 10%of the rated voltage,the output is shut down and locked after 1 second,and recovers after restarting.
Over current The user can set the over-current value to delay the oufput for 5 seconds and then shut down the output,and then resume after restarting.
Sovrapressione Users can set the overvoltage value to shut down the output voltage,and restore after restart.
Sovratemperatura Shut down the output,automatically recover or restart after the temperature drops.
