RCD Non-linear Load - Direct Supply by Shenzhen Tuowode RCD Non-linear Load Manufacturer
RCD Load
Product Overview RCD Load Nonlinear Load - Direct Supply by Shenzhen Tuowode RCD Load Nonlinear Load Manufacturer The RCD Load is a type of nonlinear analog load composed mainly of resistors (R), capacitors (C), and diodes (D). It can be used to test the actual working capacity of power supply equipment such as data center generators and UPS systems when they are carrying nonlinear loads like computers and network devices. By accurately measuring the output power and quality of the power source, it can prevent the equipment from failing to drive loads or causing pollution to the power grid in actual use, thereby ensuring power supply safety. It simulates typical nonlinear loads such as electrified railways, steel mills, ports, and aluminum electrolysis plants; as well as new nonlinear loads such as photovoltaic and wind power generation, electric vehicles, and energy-saving products.
Product Features◇Controlled by a touch screen and PLC, with corresponding upper computer operation software;◇Load power can be freely combined according to performance testing requirements, with step increments from 0.01k to full-scale power, allowing for continuous adjustment;◇The load base power factor is 0.7, enabling adjustment of power factor within the range of 0.3-1 through the free combination of active and reactive power;◇Can simulate field operation waveforms and power conditions, with harmonic, reactive, and active currents pre-set and automatically operated;◇Can simulate three-phase, two-phase, and single-phase loads;◇Three-phase loads are independently adjustable, allowing for unbalanced operation or operation in different modes;◇Measurement data can be uploaded to a PC and the process recording and storage of the testing process data can be achieved;◇Simulates transient load changes and allows for continuous adjustment of the amplitude of impulse loads;◇Features panel operation or remote control;◇Utilizes a new type of resistive element with high power density and no red heat phenomenon, the whole unit consists of a resistive load (R), a capacitor (C), and a diode (D);◇Comprehensive protection functions include AC over/under voltage, output overcurrent, DC over/under voltage, short circuit, and overtemperature;◇Equipped with a 7-inch LCD touch screen control and LCD meter display.
Product Principle
It is primarily composed of three parts: resistor R, capacitor C, and diode D.
