AC test load cabinet RCD programmable AC test load dummy load dummy load RCD cabinet nonlinear load is a nonlinear load simulation can be used to test the data center generators, UPS and other power equipment, to understand its belt nonlinear computers, network equipment and other real ability to work load. By accurately detecting the output power of the power and quality, it can not drive the load can be avoided in actual use or pollution on the grid to safeguard security of electricity supply. With today's digital society, network development, computer, network equipment and other rectifier load it has been widely used. These have the load rectifier filter circuit nonlinear characteristics, the resistance is not constant, higher output range of power supply equipment, stability requirements. Therefore, the data center back-up generators, UPS and other power supply network equipment, must be used with non-linear characteristics of the simulated load, debug detect its crest factor and other parameters. However, the conventional RLC analog load based on linear load, you can not simulate nonlinear load change characteristics, it is difficult to test the generators, UPS in data centers, network power environment in actual performance. Only use RCD non-linear loads, in order to make the most accurate judge the quality of the output power and power supply equipment. According to GB / T 7260.3-2003 "uninterruptible power supply (UPS) - Part 3: Method of specifying the performance and test requirements" and other relevant national standards, through in-depth research and testing to determine the design specifications and parameters of the standard RCD load developed The new RCD simulated load. I. Product Overview RCD load is a nonlinear load simulation can be used to test the UPS power supply, power inverter, etc., to understand their real ability to work non-linear loads computers, network equipment and other belt. By accurately detecting the output power of the power and quality, it can not drive the load can be avoided in actual use or pollution on the grid to safeguard security of electricity supply. With today's digital society, network development, computer, network equipment and other rectifier load it has been widely used. Load these rectifier filter circuit with nonlinear characteristics, the resistance is not constant, higher output range of power supply equipment, stability requirements. So the network UPS power supply, power inverter and other power supply equipment must be used with non-linear characteristics of the simulated load, debug test its crest factor and other parameters. But the traditional analog load RLC based on linear load, can not simulate nonlinear load change characteristics, it is difficult to test the UPS power supply, power inverter, etc. in the data center, web tension power environment in actual performance. Only use RCD non-linear loads, in order to make the most accurate judgment on the output power and power quality power supply equipment. According to GB / T 7260.3-2003 {uninterruptible power supply (UPS) - Part 3: Method of specifying the performance and test requirements} and other relevant national standards, through in-depth research and testing to determine the design specifications and parameters of the standard RCD load developed The new RCD simulated load.
