Load banks
Load banks for reliable power supply performance tests
Load banks, also known as load resistors, are critical devices for testing and maintaining power supply systems. They simulate electrical loads to test the performance of generators, UPS systems (uninterruptible power supplies), emergency generators, transformers and other electrical systems under real operating conditions.
Why are load banks important?
Regular testing with load banks is essential to ensure that critical power systems function reliably and are ready for use in an emergency. This is particularly important in critical infrastructures such as hospitals, data centers and industrial facilities where failures can have devastating consequences.
Advantages of load banks
- Reliability: Regular testing with load banks allows potential problems to be identified early and rectified before they lead to failures.
- Safety: Load banks provide a safe method of testing power systems without the risk of overloading or damaging the actual system.
- Efficiency: Load banks make it possible to maximize the efficiency and performance of generators and UPS systems by testing them under real-world conditions.
What types of load banks are there?
- Resistive load banks simulate pure ohmic loads and are ideal for testing generators and UPS systems under constant load conditions thanks to the use of high-power resistors.
- Inductive load banks add an inductive component and simulate motor loads, for example, making them particularly useful for applications that need to replicate real load conditions.
- Capacitive load banks provide an additional capacitive load and are often used for testing inverters.
- Combined load banks integrate resistive, inductive and capacitive components and provide a comprehensive test solution.
Areas of application for load banks
Generator tests
Load banks are often used to test the capacity and efficiency of diesel and gas power generators. They allow generators to be tested under realistic load conditions to ensure that they can provide the required power in an emergency.
UPS tests
UPS systems must be continuously tested to ensure that they can provide the necessary power in the event of a power failure. Load banks allow these systems to be tested under real load conditions to assess their capacity and efficiency.
Battery tests
Load banks are used to discharge batteries under controlled conditions. This helps to determine the actual capacity and condition of the batteries, which is crucial for planning maintenance work and replacing batteries.
Data centers
Data centers need to ensure uninterrupted power supply. Load banks help to check the load capacity and reliability of emergency power generators and UPS systems and thus ensure the continuous availability of data.
Marine and offshore
In the marine and offshore industry, load banks are used to test the power supply systems on ships and offshore platforms. These tests are important to ensure that the systems function reliably under harsh conditions.
Industrial applications
In industry, load banks are used to test motors, transformers and other electrical equipment. They help to evaluate the load capacity and efficiency of these devices and ensure that they meet production requirements.
Our expertise
We offer a wide range of load banks for various applications and requirements. Our products are designed for the highest quality and reliability and are used worldwide in the most demanding environments. Whether portable load banks from 10 kW for mobile testing or permanently installed systems up to several megawatts for continuous monitoring, we have the right solution for your needs. It is also possible to connect two or more load banks together on the control side in order to provide large outputs.
Another major strength of our load banks is their user-friendliness. The modern touch control directly on the system, via wired remote control or, when integrated into a network, via the user-friendly UI (user interface) developed in-house, allows complex, freely configurable test sequences to be carried out. The measurement results can be saved and visualized directly on the high-resolution display.
