The RCD Load Bank is a high-precision special load equipment integrating resistance, capacitance and differential control technology. It optimizes the dynamic response performance on the basis of RLC loads and realizes fast dynamic adjustment and accurate differential control of load parameters. The equipment can simulate complex dynamic working conditions such as grid transient fluctuation, sudden load change and harmonic disturbance. It is mainly used for dynamic performance testing and stability verification of high-end power equipment, precision inverter power supplies, smart grid equipment and power quality control devices. It can accurately capture equipment transient response parameters, making up for the shortcoming that conventional load banks cannot simulate dynamic non-linear loads, and is suitable for high-precision testing scenarios such as high-end scientific research, power quality inspection and precision equipment R&D.
