Description

Summary

Single output: Power 9000W

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

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.
