RCD load is a kind of nonlinear analog load, which can be used to test the power generation unit of data center, UPS and other power supply equipment, to understand the real working ability of the nonlinear load such as computer and network equipment. Through accurate detection of power output and quality of power supply, it can avoid driving load or pollution to power grid in actual use, so as to ensure the safety of power supply.

Product features

With the development of digitalization and networking in modern society, rectifying loads such as computers and network devices are widely used. The load composed of rectifier and filter circuit has nonlinear characteristics, and its resistance is not constant. It has higher requirements for the output range and stability of the power supply equipment. Therefore, for the data center backup generator, network power supply UPS and other power supply equipment, the analog load with nonlinear characteristics must be used to test the peak factor and other parameters.
However, the traditional RLC analog load is based on the linear load, which can not simulate the change characteristics of the nonlinear load, and it is difficult to test the actual performance of the starting power unit, the UPS in the data center and the network power environment. Only by using RCD nonlinear load can we make the most accurate judgement of the output power and power quality of the power supply equipment. At present, there are still no mature technical specifications and application cases in this field.

The principle of its circuit is shown in the following diagram：

This product can be widely used in data center, network communication, finance, insurance, school and other fields such as backup generator, UPS power supply detection and maintenance, fill the market gap.

Main functions and parameters：

1. The nonlinear load of RCD is composed of resistive load, capacitive load and analog impedance resistor. The impedance of the load can be adjusted by the input analog impedance of an independent circuit. The load power can be nonlinear loaded.
2. The power factor of the load reference is 0.7, and the power factor can be adjusted in the range of 0.2-1 through the free combination of active power and reactive power.
3. The rated voltage and rated power of the load can be customized according to the needs of users.
4. After loading, the voltage, current, active power, reactive power, power, power factor, frequency and other parameters can be measured, and the user can be used to test the peak factor.
5. Through harmonic analysis, the 2~50 harmonic content and total harmonic content of voltage and current can be detected, and the quality of power supply under the condition of nonlinear load can be detected.
6. Load with multi-function measuring instrument, can display voltage, current, power, power factor, frequency and other parameters.
7. Through computer software control load, automatic test can be realized, and test data can be displayed, recorded and managed.
8. All test data can be stored in the software database, and can be Querying Historical test data at any time, exported to Excel and other general format files, and support printing.
9. The load has multiple protection functions, such as overvoltage, overcurrent, overheating, fan abnormal and so on. The load can be automatically unloaded when the load is dangerous. It can also be forced to unload by manual stop switch.

The product is customized according to the customer's request.
