Our range of Resistive Load Banks
The resistive load bank is a precision test instrument that simulates purely resistive electrical equipment. It generates a precisely controllable pure active load by consuming electrical energy. It is specially used for safe and stable load testing, aging testing and performance verification of power equipment such as generators, UPS, and photovoltaic inverters in laboratories or on-site. Its core advantage lies in providing simple and reliable resistive load simulation without harmonic interference and power factor shift, ensuring that the test results truly reflect the load capacity, efficiency, voltage drop, temperature rise and steady-state working characteristics of the equipment under full-load pure resistive conditions.

Resistive Load Banks FAQ
1
What Load Bank Packages Do You Have?
Our resistive load banks offer a wide range of specifications. For power, we have models from 100kW to 8000kW (covering common application needs like generator set type tests and factory inspections). Voltage supports 400V and 6.3/10.5kV, with frequencies at 50Hz or 50/60Hz. Dimensions and weights vary by power (e.g., 100kW model:11009001000mm,~320Kg). We also provide "turnkey project" solutions—covering equipment supply, installation, and full - process support for seamless deployment.
2
What design features make your resistive load banks suitable for different environments?
Our resistive load banks (e.g., the 5000kW model for power plants) feature a container - type design for robust structure. The cooling system uses horizontal air intake and vertical air exhaust, plus a top air - guide hood—allowing operation even in rainy weather. These designs ensure adaptability to various environmental conditions, from indoor factories to outdoor power plant sites.

5
Why is a resistive load bank the preferred choice for generator testing?
In generator testing, a resistive load bank can:
（1）Accurately simulate real power consumption；
（2）Support 25% / 50% / 75% / 100% graded loading；
（3）Verify the generator's voltage, frequency, and thermal stability under full load；
（4）Also, it avoids carbon buildup problems caused by long-term light-load or no-load operation of the generator, making it the most basic and reliable load type for generator testing；
6
Are resistive load banks suitable for continuous operation and aging tests?
Excellent.
Resistive load banks have a simple structure, linear load distribution, and offer:
（1）Long-term continuous operation capability；
（2）Stable thermal performance；
（3）Low failure rate
They are commonly used for durability and aging tests of industrial power supplies, power generation equipment, and power systems.
7
Can resistive load banks meet the needs of applications with different voltage and power ratings?
Yes. Resistive load banks typically support:
