Q1: Can this load bank simulate GB200 / GB300 rack heat flux 1:1?
A1: Yes. It can reproduce the exact power consumption and heat flux of GB200 / GB300 NVL72 GPUs 1:1, matching the real rack thermal profile for pre-acceptance testing without physical GPUs.
Q2: Does it support AC415V Line / 230V Phase three-phase power system?
A2: Yes, it supports 415V Line / 230V Phase 3-phase power. 400V/230V version and 480V(277V phase) customized option are also available.
Q3: Can multiple load banks be paralleled for multi-rack cluster testing?
A3: Yes. Multiple units can be synchronized and paralleled to simulate multi-rack GPU cluster load for large-scale data center verification.
Q4: Can it auto generate acceptance test report for data center project?
A4: Yes. The system automatically records test data and exports editable acceptance test reports (CSV/PDF) for data center project handover.
Q5: Is on-site commissioning service available overseas?
A5: Yes. We provide overseas on-site commissioning, training and technical support; remote online commissioning is also available as an alternative.
Q6: What is the step resolution of load adjustment?
A6: Standard load step resolution is 1kW. Custom finer step resolution can be configured upon request.
Q7: Does it support remote control via MODBUS / TCP/IP?
A7: Yes, MODBUS-RTU and MODBUS TCP/IP are built-in. It supports remote load setting, real-time data reading and alarm monitoring.
Q8: What is the cooling method of this rack load bank? Air cooling or liquid cooling?
A8: Air cooling is standard. Liquid cooling version is available for high heat density GB300 rack simulation on request.
Q9: What is the maximum continuous operating time at full load?
A9: It supports 24/7 continuous stable operation under rated full load.
Q10: Can it simulate dynamic load fluctuation for power failure & UPS switching test?
A10: Yes. It supports programmable dynamic load profiles, step/ramp load changes to simulate power outage and UPS transfer switching tests.
Q11: What protection functions are built-in (overheat, overcurrent, overvoltage, emergency stop)?
A11: Built-in protections include over-temperature, over-current, over-voltage, under-voltage, fan failure and emergency stop. It will automatically cut off load once alarm triggers.
Q12: What is the delivery lead time for standard & customized models?
A12: Standard models: 4–6 weeks. Customized liquid cooling / special voltage models: 8–12 weeks, subject to project specification.
Q13: Can the heat distribution match the actual GPU layout inside the rack?
A13: Yes. We design the internal heat distribution and air outlet layout to replicate the thermal distribution of real GPU arrangement inside the rack.
Q14: What data parameters can be recorded during the test?
A14: It records voltage, current, active power, apparent power, power factor, temperature, operating time and alarm logs.
