// FEATURES

Technological Breakthroughs

High-Flow Forced Air Cooling
The unit features an efficient forced-air cooling design utilizing a practical side air intake and side exhaust configuration. This optimized airflow management allows the system to maintain high operational reliability and stability during rigorous thermal load testing cycles
Rack-Optimized Footprint
Engineered to easily maneuver into standard data center cabinet infrastructures, this compact unit features field-ready dimensions of approximately 1400mm × 950mm × 1300mm (L × W × H). Weighing roughly 200kg , it provides the ideal footprint for flexible indoor on-site commissioning.
Intelligent Local & Remote Control
Users can manage testing operations via local control modes using manual panel switches or transition to remote automatic control using a dedicated RJ45 communication interface. The local panel features an integrated display showing real-time three-phase voltage, current, active power, reactive power, apparent power, power factor, and frequency.
Precision Load Adjustments
The system delivers a maximum resistive load capacity of 150kW configured across a highly flexible 8-step block sequence (3, 6, 12, 18, 20, 21, 30, and 40 kW). It achieves an exceptional overall unit load accuracy of ±1% and a display accuracy of 0.5 level , with a three-phase imbalance strictly limited to ≤1%.
Fluctuating-Safe Continuous Operation
Engineered with premium Class F insulation materials , the system is fully rated for uninterrupted continuous operation modes. It includes a specialized one-touch load adjustment feature that allows operators to preset desired power values before engaging the main load switch, completely preventing power fluctuations during step transitions.
Multi-Tier Integrated Safety Protection
Built with a robust interlock control to prevent operational command conflicts , the unit features an advanced safety protection matrix. This includes a one-touch forced unloading emergency stop , automated overvoltage and temperature safety unloading with audible/visual alarms , a fan interlock to prevent loading without power to the fan , and a dedicated chassis grounding terminal.

Application Scenarios

Electrical Performance & Step Testing
  • Power Distribution Validation: Specifically designed to test AC three-phase four-wire 415V / 50Hz power systems, verifying system stability, power factor performance (PF=1), and three-phase balance (≤1%).
  • Transient & Steady-State Analysis: Utilizes the highly granular 8-step resistive configuration (from 3kW up to a maximum of 150kW) to execute precise step-response tests, checking how upstream power supplies handle sudden load changes with an overall unit accuracy of ±1%.
01
Data Centre Integrated Cooling Verification
  • Thermal Load Simulation: Acts as a precise heat-load proxy to test and validate room-level data center cooling infrastructures, including CRAC units and hybrid cooling deployment.
  • Airflow & Containment Testing: The forced-air design with side air intake and side exhaust allows engineers to safely simulate real-world server heat dissipation, proving the efficiency of hot/cold aisle containment layouts before active servers are deployed.
02
Protection & Safety Interlock Validation
  • Control Safeguard Verification: Tests the responsiveness of external control networks and breakers by utilizing the load bank's built-in interlock control switch to prevent conflicting command operations.
  • Emergency Fault Simulation: Safely validates facility-side response times and trip mechanisms during simulated emergency events using the unit's one-touch forced unloading emergency stop, fan interlock protection, and automated overvoltage/temperature trips.
03
Server Rack & CDU Infrastructure Load Testing
  • High-Density Heat Replication: Mimics the exact thermal output of high-density server architectures to stress-test the heat exchange capacities of liquid-cooled IT cabinets and direct-to-chip cooling loops.
  • CDU Capacity Validation: Provides a stable, continuous 150kW thermal load to evaluate the real-world performance, flow thresholds, and heat-rejection limits of specialized Cooling Distribution Units (CDUs) during extended commissioning cycles.
