Product Introduction
The SIRL-5500L is a high-capacity Resistive / Inductive (R/L) Load Bank specifically designed for testing large diesel generators, UPS systems, data centers, power grids, and Battery Energy Storage Systems (BESS).
The complete system is rated at 5500kVA and consists of two independent 2750kVA sections, which can operate separately or simultaneously to provide up to 4400kW resistive load and 3300kVar inductive load at a 0.8 power factor.
With its containerized design, top-airflow cooling structure, and smart local/remote control system, the SIRL-5500L is ideal for factory acceptance testing (FAT), site commissioning, and long-duration reliability verification.

FAQ
1
Why does the 5500kVA load bank use two independent 2750kVA systems?
The dual-system architecture provides redundancy, flexible capacity matching, and allows maintenance on one section without interrupting operation of the other section.
2
What are the advantages of a resistive/reactive load bank over a purely resistive load bank?
It can simultaneously provide active and reactive power, more accurately simulating real industrial loads such as motors, pumps, and HVAC systems.
3
Why is a top-airflow design used?
Top airflow improves heat dissipation, prevents hot-air recirculation, and is particularly suitable for containerized installations.
4
Why are Ni-Cr alloy elements used?
Ni-Cr elements offer excellent high-temperature resistance, oxidation resistance, and long service life, with operating temperatures up to approximately 1200°C.
5
How is long-term safe operation ensured?
The system includes fan overload protection, low-airflow protection, over-temperature protection, MCCB protection, local/remote interlock, and emergency stop circuits.
6
Does the load bank support remote control?
Yes. It supports Modbus TCP communication via an RJ45 interface for integration with PLC and SCADA systems.
7
What is the load adjustment resolution?
Both resistive and reactive loads have a minimum adjustment step of 1kW / 1kVar.
8
Why are tin-plated copper busbars used?
Tin-plated busbars reduce contact resistance, improve current-carrying capacity, and enhance long-term reliability.
9
Which generator systems can be tested?
Diesel generators, natural gas generators, gas turbines, and microgrid power systems.
10
Can different power factors be simulated?
Yes. Independent control of resistive and inductive loads allows flexible power factor adjustment.
11
Why are 12 industrial blowers installed?
The multi-fan configuration provides sufficient airflow (70m³/kW/h) to maintain safe operating temperatures during high-power testing.
12
What environments is the load bank suitable for?
With IP55 control protection and IP54 enclosure protection, it is suitable for outdoor, high-temperature, and industrial environments.
13
How does the unit adapt to different voltages?
The load bank operates at 480V and can also run at 410V and 380V with proportional power derating.
14
What are the benefits of the modular design?
Modular resistors, contactors, fans, and fuses can be replaced quickly, reducing downtime and maintenance costs.
15
Which industries is this product most suitable for?
Data centers, generator manufacturers, energy storage projects, EPC contractors, power utilities, oil & gas facilities, airports, hospitals, and other mission-critical infrastructure applications.
16
Typical product delivery time?
At least 8 weeks.
17
Warranty service?
2 years.
18
Do you provide installation and testing support?
Yes, Rata provides on-site testing services, including equipment installation, configuration, and data logging.
