Load banks are categorized as testing equipment that are used to commission, maintain and simulate a typical electrical load / source in order to assess the electrical power source such as a generator, UPS or battery systems. A test environment thus created allows the load bank to accurately replicate and verify the actual or real load that will ultimately be connected to the power source.
Load banks are used to test electrical power output from sources such as generators, UPS & Battery systems while carrying out commissioning and maintenance work. By simulating the actual load engineers can test all required electrical and control parameters before connecting the actual equipment such as computer servers, power generation equipment, Air Conditioning systems etc.
The resistive load bank allows you to test a prime mover and a generator at 100% capacity. This method employs a straightforward process for measuring loads: electrical energy is converted to heat via power resistors, and the heat is dissipated from the load bank by air using high power convection cooling fans.
Resistive Loads banks come in a wide range of options based on their size to the power range required. Here we focus on these 2 resistive load banks
A popular choice used especially in data centres to test the entire power line from the source to the Server bay. Load banks also find a place alongside power equipment such as UPS, Generators for a wide range of industrial activities. From being rack mountable to being portable ( with help of swivel wheels ), they are custom suited to customers requirements.
The Data center industry is growing exponentially with new facilities being built globally. Power consumption in Data centers is also growing and the need for reliable power cannot be under-estimated. Power outages and unreliable power can not only take down expensive equipment, it also leads to loss of revenues due to these outages.
When a new data center is being commissioned or when periodic maintenance / testing of power quality is required – then Data center managers turn to Load banks to help identify potential issues such as faulty electrical components or systems that are bound to fail when the actual power source is applied.
Lower capacity Resistive Load banks in a Rack mountable design can fit a standard server rack and are used to simulate the heat and power consumption of that of a normal server to test potential errors in power without the risk of using expensive servers.
During the process of commissioning a data center, the room design, placement of equipment and the effectiveness of the cooling system in the room has to be tested and verified. This has to happen prior to installation of servers and other equipment. Server mounted Load banks play a very significant role wherein the conditions of production servers can be replicated precisely by varying the electrical load, heat and airflow. Data center managers can validate the cooling system’s ability to manage the designed temperature delta of the production servers.
KWK Resistors is India’s only ISO 9001 Certified Power Resistor Manufacturer to provide a CE certified Rack Mountable Resistive Load Bank. The ALPHA series of Load Banks fit into a standard 6U 19″ Server Rack system or can be also placed as a table-top test equipment device. Powers up to 5kW are available with these series and combinations of these units can provide for higher Power testing requirements where required. Power supply shut-off due to over current and over temperature ensures safe operations during testing and commissioning.
