// Overview

An intelligent, rack-optimized server simulation system designed for the rigorous commissioning of data center infrastructure and the precision testing of high-capacity cooling units.

The DT-RM-LBK-12 is engineered to mimic the real-world thermal dissipation of high-density server hardware, providing a high-accuracy environment to validate AC 230V/415V power loads.

Built to standard rack dimensions for seamless facility integration, the unit features multiple adjustable power levels to facilitate granular assessments of server room wiring, load capacity, and temperature rise. With a focus on industrial stability and high power accuracy, this equipment ensures that your precision air conditioning and power distribution systems are fully optimized for high-demand operational environments.

Technological Breakthroughs

Rack-Optimized 6U Form Factor
Engineered for seamless integration into standard data center enclosures, this highly compact 6U chassis measures approximately 431mm × 500mm × 268mm. Weighing only 25kg and equipped with heavy-duty front panel side handles and a smooth scratch-preventive bottom surface, it is purpose-built for agile, single-operator field deployment.
Flexible 7-Step Load Segmentation
Provides highly adaptable load testing across a 12kW maximum capacity, featuring a granular 7-step segmentation block (1kW, 1kW, 2kW, 2kW, 2kW, 2kW, 2kW). Each phase is perfectly balanced at 4kW across an AC 230V / 415V three-phase configuration with a true unity power factor (PF = 1) and a full-load accuracy of $\le \pm 3\%$.
Plug-and-Play Server Interface
Equipped with a clean, low-profile rear panel connection hub featuring 6× standard IEC-C14 power sockets. This configuration mirrors actual high-density server power draw paths, allowing engineers to connect directly to standard rack power distribution units (PDUs) without custom cabling arrays.
Industrial-Grade Material Architecture
Built to withstand extended, high-temperature load testing cycles. The internal heating elements leverage nickel-chromium alloy resistance wire protected by a stainless steel casing and integrated stainless steel fins for superior heat dissipation. All internal cabling is constructed from premium high-temperature resistant, multi-core flame-retardant flexible cables matched with Class F insulation.
Smart Airflow & Fan Redundancy
Features a specialized front-intake and rear-exhaust airflow design that perfectly replicates standard server thermal exhaust profiles, with completely sealed side panels. The cooling system is powered by an array of 4 cooling fans engineered with active fault tolerance—allowing the system to maintain stable, continuous operation even if one fan experiences a field failure.
Robust Mechanical Safeguards
Equipped with manual miniature circuit breakers (1P MCBs) for zero-stick, arc-free load stepping. System protections include an automated overcurrent trip, an integrated cooling fan interlock that requires Phase A to power the fans before a load can be engaged, and a 80°C over-temperature sensor that triggers immediate local buzzer alarms and a visual fault light.

Application Scenarios

High-Density Server Thermal Simulation
  • Airflow Optimization: Replicates the exact front-intake and rear-exhaust airflow profiles of active IT equipment to test row-level precision air conditioning performance.
  • Containment Validation: Allows commissioning engineers to safely simulate actual server heat generation to prove the efficiency of hot/cold aisle containment setups prior to actual server population.
01
Rack-Level PDU & Circuit Capacity Verification
  • PDU Load Balancing: Connects directly to rack power distribution units using standard rear-panel IEC-C14 inputs to verify circuit stability, branch monitoring calibration, and three-phase power balancing (4kW per phase).
  • 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
Redundant Cooling Path Failover Analysis
  • N+1 Fan Testing: Evaluates how the server environment responds during localized heat rejection anomalies, utilizing the unit’s active fan fault-tolerance mechanism to keep testing live during a single fan failure event.
  • Continuous Stress Testing: Leverages robust nickel-chromium elements and F-class insulation parameters to execute long-duration, continuous-operation thermal testing without data center degradation.
03
Safety Interlock & Alarm Sequence Validation
  • Startup Sequence Verification: Tests critical infrastructure control protocols by validating the unit’s fan interlock mechanism, ensuring that auxiliary systems follow the mandatory safety order of operations.
  • Emergency Threshold Audits: Safely tests localized monitoring alerts and site alarm relays by exercising the load bank's integrated 80°C over-temperature audio/visual alarms and manual MCB overcurrent trip features.
