Rack-mounted load bank multi-scenario adaptation selection guide

Here are some guidelines for rack-mounted load bank multi-scenario adaptation selection:

Data center

• Power requirements: Data centers usually have a large number of servers and other equipment. It is necessary to select a rack-mounted load bank with appropriate power according to the scale of the data center and the expected load peak. The power is generally large, ranging from tens of kilowatts to hundreds of kilowatts.

• Accuracy requirements: For power supply testing in data centers, the accuracy requirements are relatively high to accurately evaluate the performance of power supply equipment, such as the accuracy must reach ±0.5% or higher.

• Adjustment method: It is recommended to select a load bank with remote control and automatic adjustment functions to facilitate centralized control and automated testing by computer room managers in the monitoring room.

• Protection level: The data center environment is relatively good, and the general protection level of IP20 or above can meet the requirements.

Communication base station

• Power selection: Determined according to the number of equipment and power requirements of the base station. The power of the load bank of the general base station is between several kilowatts and tens of kilowatts. At the same time, considering the possible expansion needs of the base station, a certain power margin should be appropriately reserved.

• Load type: Most of the equipment in the communication base station is a switching power supply, etc. It is necessary to select a mixed load bank that can simulate resistive, inductive and capacitive loads to more accurately test the performance of the power supply under different load characteristics.

• Cooling method: Since communication base stations are usually located outdoors or in limited space in the computer room, it is recommended to select a load bank with forced air cooling to ensure normal operation in a high temperature environment.

• Reliability: Communication base stations require equipment to have high reliability, so it is necessary to select a well-known brand and reliable rack-mounted load bank to reduce the probability of failure and ensure the stable operation of the communication system.

Laboratory

• Accuracy requirements: Laboratories are used for scientific research and product development, etc., and the accuracy of test data is extremely high. Load banks with very high accuracy should be selected, such as an accuracy of ±0.1% or even higher.

• Load type and adjustment method: It is necessary to simulate various load conditions, so the load bank should have a variety of load types and flexible adjustment methods, including manual, remote control and automatic adjustment, to meet the needs of different experiments.

• Functional diversity: Laboratories usually want load banks to have more functions, such as data recording, analysis, and report generation, so that experimenters can conduct in-depth research on test results.

Industrial production site

• Protection level: The industrial site environment is relatively harsh, with dust, oil, moisture, etc., and load banks with higher protection levels should be selected, such as IP54 or higher protection levels, to prevent dust and water from entering the equipment and affecting its normal operation.

• Power and overload capacity: Select a suitable load bank according to the power of the industrial production equipment, and take into account the overload that may occur during the startup and operation of the industrial equipment. The load bank should have a certain overload capacity and be able to withstand short-term overload without damage.

• Ruggedness and durability: The equipment at the industrial site needs to withstand frequent use and certain vibrations, shocks, etc. Therefore, the rack-mounted load bank should adopt a sturdy shell and structural design, and the internal components should also have good stability and durability.

Ship and offshore field

• Protection level: In ship and offshore environment, equipment faces corrosion problems such as salt spray and moisture, so the load bank needs to have a higher protection level, such as IP65 or higher, to prevent seawater and salt spray from corroding the equipment.

• Load characteristic simulation: The load characteristics of the power system on the ship are complex, and the load bank needs to be able to accurately simulate the load of the ship generator under different working conditions, including sudden load addition and unloading, etc., so it is usually necessary to select a load bank with special load simulation function.

• Vibration and shock resistance: The ship will vibrate and shock during navigation, and the load bank should have good vibration and shock resistance to ensure that it can work stably during the operation of the ship without failure or damage.
