FAQ
1
Why choose a resistive and inductive load bank instead of a purely resistive load bank?
A resistive and inductive load bank more accurately simulates real industrial loads such as motors, pumps, and HVAC equipment. This enables more realistic generator performance testing under actual operating conditions.
2
What is the advantage of 0.5kW and 0.5kVar load resolution?
Fine load resolution allows engineers to precisely match target power levels, improving testing accuracy and providing smoother load adjustments during commissioning and acceptance testing.
3
What types of equipment can be tested?
The SIRL-250L 250kVA is suitable for diesel generators, gas generators, UPS systems, transformers, power distribution equipment, BESS, and critical power infrastructure.
4
What electrical parameters can be monitored in real time?
The integrated monitoring system displays voltage, current, frequency, active power (kW), reactive power (kVar), apparent power (kVA), and power factor (PF) in real time.
5
Does the load bank support remote operation?
Yes. The system supports both local operation and PC-based remote control through Modbus TCP communication, allowing easy integration into automation platforms.
6
How does the load bank ensure operational safety?
Multiple protection systems—including fan overload protection, low airflow detection, thermal shutdown, MCCB protection, local/remote interlock, and emergency stop—continuously monitor the operating status to ensure safe and reliable testing.
7
Can the load bank perform continuous full-load operation?
Yes. The industrial cooling system and high-quality resistor elements are designed for continuous-duty operation, ensuring stable performance during extended testing periods.
8
Why is an integrated generator tester beneficial?
The built-in 8961 F2 generator tester combines load control and electrical measurement into one platform, simplifying testing procedures while improving efficiency and data accuracy.
9
Is the load bank suitable for outdoor installation?
Yes. The IP54 control compartment, IP55 enclosure, and industrial enclosure design provide reliable protection against dust and environmental conditions, making the unit suitable for both indoor and outdoor applications.
10
Which industries commonly use this product?
The SIRL-250L 250kVA is widely used in generator manufacturing, power utilities, data centers, EPC contractors, electrical contractors, UPS manufacturers, BESS projects, industrial facilities, hospitals, airports, and other mission-critical power applications.
11
Typical product delivery time?
6 weeks.
12
Warranty service?
2 years.
13
Do you provide installation and testing support?
Yes, Rata provides on-site testing services, including equipment installation, configuration, and data logging.
