Key Product Features
Triple-Mode Control (Local / Remote / Intelligent): Offers maximum operational flexibility. Users can choose Local control via the cabinet panel, Remote control via an external remote control box, or Intelligent control via PC software. A hardware interlock switch ensures that only one mode is active at any time, completely preventing operational conflicts.
One-Key Load/Unload: Both manual and software controls support preset-power loading. Users simply set the target power value and press the master switch; the load bank engages smoothly at the exact preset value, eliminating load fluctuation during power transitions.
Comprehensive Local Metering: The local control panel is equipped with precision instruments displaying real-time 3-phase voltage, 3-phase current, active power, frequency, and more.
Product Advantages
Enhanced Accessibility Features: Designed for operator convenience, the control panel includes an integrated lighting switch (for low-light environments) and a reserved single-phase AC220V/50Hz power socket, providing temporary power for laptops or other field devices.
Flexible Communication Interfaces: Intelligent control utilizes a photoelectric-isolated RS485 interface for superior anti-interference and stable communication. Optional USB or RS232 connectivity is also supported via converters.
Dual Load Patterns (Manual & Automatic): The software supports simple manual input loading or complex automatic multi-stage sequences (e.g., 0%→25%→50%→75%→100%→110%) with user-defined durations for each step.
Parallel Operation Management: When multiple load banks operate in parallel, the software can centrally manage the entire system, displaying and recording parameters for each individual unit as well as the combined system performance.
Professional Data Export: All curves and graphs are exportable as .doc files, while raw test data is saved as .xls reports, both fully printable for documentation and compliance.
Product Advantages
Unmatched Operational Flexibility: The addition of a Remote Control Box allows operators to safely control the load bank from a distance, away from the heat and noise, while the Intelligent PC mode enables fully automated, unattended testing.
Superior Signal Stability: Photoelectric isolation on the RS485 communication line provides exceptional resistance to electromagnetic interference, ensuring reliable data transmission even in electrically noisy industrial environments.
Operator-Centric Design: The built-in panel lighting and 220V auxiliary power socket demonstrate a focus on real-world usability-allowing technicians to power their laptops and work comfortably in dimly lit equipment rooms, containers, or outdoor sites.
Rapid Fault Diagnosis: The software visually monitors system status and, in the event of an abnormal protective shutdown, clearly displays the specific trigger reason (e.g., over-temperature, fan failure), drastically reducing troubleshooting time.
High-Resolution Data Capture: With a minimum data collection interval of just 1 second, the system captures fast transients and steady-state behaviors with high fidelity.
Turnkey Reporting: Automated generation of curves (Voltage, Current, Power, Frequency, Power Factor) and tabular data means zero manual compilation-ideal for third-party inspections, factory acceptance tests (FAT), and regulatory compliance.
Application Scenarios
Field Commissioning & Factory Acceptance (FAT): The remote control box and local panel make it easy to conduct standard step-load tests on generator sets and UPS systems directly on the production floor or at the installation site.
Outdoor & Containerized Deployments: The built-in lighting switch and 220V socket are invaluable for technicians working inside ISO containers, marine vessels, or remote telecom stations where auxiliary power and lighting may be limited.
Large-Capacity System Testing: Parallel testing capability allows multiple units to be linked for testing ultra-high-power sources such as utility-scale wind farms, data center backup generators, and industrial turbines.
