Both the host computer test software and the touch screen embedded in the equipment can set and monitor the detection process, monitor the charging status and fault information in real time, simulate various types of faults, and test the charger's response to faults.
The high-power load box is mainly used for performance testing and aging of online high-power, inverters, switching power supplies and diesel generator sets in electric power, shipbuilding, radio and television, telecommunications and other departments and manufacturers. Unified segmented power input, energy-consuming working mode, and forced air-cooling heat dissipation greatly ensure the reliability of constant power discharge. Produced with independent intellectual property rights of new power-consuming components, it has high power density, no red heat phenomenon, and automatic overheating Protection function, when the fan is not rotating, overheating and burning will not occur. It has a long safe life. The whole machine adopts a modular design, is simple to operate, and can be maintained easily. Parameters such as voltage and current can be tested according to customer requirements, which is suitable for large customers. Power AC power equipment provides scientific detection means. ■The discharge power can be combined and set at will through the operation panel according to the performance parameter testing requirements.
■Simulate the occurrence of resonance in AC power equipment, and effectively and accurately detect the anti-islanding protection function of the grid-connected inverter.
■Test the working efficiency, full load operating output power and load capacity of various inverters.
■Simulate various complex working environments and detect the comprehensive working performance of the inverter in various environments.
■For inverters with two different output specifications, , and , both can accurately and easily debug the occurrence of resonance points and meet the anti-islanding test. This is the first of its kind in China. Resonance test settings include inductive power consumption and capacitive power consumption. At resonance, theoretically the inductive and capacitive reactive powers cancel each other out and the reactive power is reduced.
