Bidirvolt builds custom load bank systems that turn power and cooling uncertainty into measurable test data before data centers, generators, UPS systems and critical infrastructure go live.
Bidirvolt rack mounted load banks simulate IT rack power and heat load before servers are installed. They support data center commissioning, liquid-cooled rack testing, CDU checks, PDU validation, UPS load testing.
Each system can be configured around rack space, kW rating, voltage, phase, frequency, cooling method, control interface, and reporting requirements. That makes the load bank useful for engineers who need test data, not just a temporary electrical load.
The right rack mounted load bank depends on the rack power profile, test duration, cooling method, and commissioning records your team needs to hand over.
| Power rating | Configured by kW or kVA per rack, per module, or per test group. Typical liquid-cooled rack units can be sized around high-density IT rack simulation requirements. |
|---|---|
| Electrical input | Voltage, phase, frequency, current, breaker size, and connector type are matched to the rack PDU, test panel, temporary source, or commissioning distribution board. |
| Cooling method | Air-cooled, liquid-cooled, or hybrid configuration depending on whether the project must release heat into the room or transfer heat into the CDU liquid loop. |
| Rack configuration | Rack U height, depth, cable access, coolant connection position, and service clearance are reviewed before the design is finalized. |
| Control and reporting | Local HMI, PLC logic, Modbus RTU/TCP, PC software, remote operation, data logging, and Excel/PDF report export can be configured for commissioning records. |
Send kW, voltage, rack size, cooling method, test duration, and report requirements for a configuration review.
Request ConfigurationA rack mounted load bank applies a controlled electrical load inside or near the IT rack footprint. Commissioning teams use it to prove power paths, rack density assumptions, cooling behavior, and monitoring points before live IT equipment arrives.
Portable and floor-standing load banks are useful for many power tests, but they do not always represent the physical constraints of an IT rack. A rack-based test setup keeps the load closer to the final operating condition.
This is especially useful when the project needs short cable paths, repeatable load steps, controlled airflow or coolant connections, and clear data from each rack position.
A rack mounted load bank can support equipment-level checks and integrated systems testing. The sequence should be planned with the commissioning authority, electrical contractor, cooling team, and controls team.
Connection, communication, alarms
Confirm rack position, power connection, communication, emergency stop, and protection alarm status before applying load.PDU, UPS, switchgear response
Apply staged loads and record voltage, current, frequency, load percentage, timestamps, and alarm events.Flow, temperature, pressure
Use sustained heat-load simulation to track inlet and outlet temperature, coolant flow, pressure, delta-T, and leak alarm state.Generator, UPS, thermal stability
Keep load active during transfer or failover tests, then hold the required load for trend logs and final acceptance records.Planning a full data center test? Review the related solution for liquid-cooled commissioning and high-density rack validation.

| Test target | Load bank role | Data to record |
|---|---|---|
| Rack PDU and feeder | Apply the planned rack load and confirm feeder stability. | Voltage, current, load step, breaker behavior, alarm status. |
| UPS and generator transfer | Keep load active while the backup power system transfers or recovers. | Transfer time, voltage dip, recovery behavior, event log. |
| CDU and liquid loop | Simulate rack heat load through the liquid-cooled interface. | Flow, inlet/outlet temperature, pressure, delta-T, leak alarm. |
| Commissioning report | Export repeatable data for handover and client review. | CSV, Excel, PDF, trend charts, alarm logs, screenshots. |

Hold load for the required duration and record thermal, electrical, and alarm behavior for handover.
Choose the load bank format based on where the heat must go, how much rack space is available, and whether the test needs to validate the CDU loop.
| Load bank type | Best for | Cooling method | Data center fit |
|---|---|---|---|
| Air-cooled rack load bank | Basic rack power checks and short-duration IT load simulation. | Heat is released into the room through fans and airflow. | Useful where room HVAC can absorb the heat and liquid cooling is not under test. |
| Liquid-cooled rack load bank | CDU commissioning, liquid-cooled server simulation, and high-density rack acceptance. | Heat is transferred directly into the CDU liquid circuit. | Best match for liquid-cooled data center projects and CDU validation. |
| Containerized load bank | Large site-level generator, UPS, or grid acceptance testing. | Usually air-cooled and placed outside or in a dedicated test area. | Good for total facility capacity tests, but not a direct replacement for IT rack/CDU validation. |

Send Test RequirementsA rack-mounted load bank applies a controlled electrical load at rack level. In data centers, it helps simulate IT equipment before servers are installed, check power distribution, support cooling validation, and collect commissioning records.
A portable load bank is usually moved around the site for general electrical testing. An IT rack load bank is configured around rack space, rack power density, short connection paths, and repeatable test positions.
Yes. A rack-mounted load bank can be configured for liquid-cooled or hybrid testing when the project needs CDU checks, coolant connection review, temperature tracking, flow validation, or high-density rack heat-load simulation.
Useful inputs include kW or kVA rating, voltage, phase, frequency, rack size, cooling method, load step resolution, test duration, control interface, reporting format, and any PDU, UPS, generator, CDU, or BMS integration points.
They can. Bidirvolt can configure PLC/HMI control, Modbus RTU/TCP, PC software, remote operation, data logging, and Excel or PDF report export depending on the project requirements.
