WEHO SP-9000 Series: 9000W Intelligent Programmable DC Power Module with Advanced Modbus Telemetry

The WEHO SP-9000 is an elite, high-capacity switching power supply engineered to deliver an immense 9000W of precise DC power. Operating at peak 100% capacity on 195-265VAC inputs (and 50% capacity on 95-190VAC), it provides a comprehensive lineup of DC outputs from 24V up to 220V, boasting a staggering maximum current of 337.5A (on the 24V model). Achieving up to 93% peak energy efficiency, this module is built for total automated system control. It features ultra-wide output adjustability, native RS485 Modbus communication, and supports highly customizable hardware interfaces including a 12V/0.5A auxiliary supply and dry-contact alarm signals. The rugged 432 x 179 x 242 mm enclosure weighs 12.5 kg, delivering exceptional power density for heavy industry.

Differentiated Advantages

The SP-9000 separates itself from conventional high-wattage power supplies through its highly customizable fault-logic and deep integration capabilities:

Programmable Surge Tolerance (5-Second Delay): Unlike standard industrial units that instantly shut down during current spikes, the SP-9000 features a user-programmable over-current logic. Operators can set a specific over-current threshold with a 5-second delay. This uniquely allows the system to absorb massive startup surges from heavy inductive motors or capacitive loads without triggering a disruptive system-wide reset.

Absolute Zero-to-Peak Tuning: It breaks the mold of static converters by offering extreme linear adjustability. Both output voltage and constant current can be meticulously dialed in from absolute zero up to their maximum over-ratings (e.g., 0-242V continuous tuning on the 220V model). This provides the surgical precision required for highly sensitive electrochemical processing, EV battery formation, and rigorous R&D stress testing.

Customizable Industrial Telemetry: Designed for seamless SCADA and PLC ecosystem integration, it pairs its RS485 Modbus protocol with customizable hardware feedback. With bespoke options for dry-contact “Power Good” alarm signals (≤36V, 0.1A) and high-level remote switching, it allows facility engineers to monitor power health in real-time, drastically reducing the need for expensive third-party relays and secondary wiring in OEM control cabinets.
