Performance characteristics
u Flexible combination of voltage and current output The output can reach 6-phase voltage and 6-phase current, which can be combined to achieve conventional 4-phase voltage, 3-phase current type, 6-phase voltage type, 6-phase current type, and 12-phase output mode, which can be compatible with traditional output modes. This kind of test method can also conveniently carry out the three-phase transformer differential test and the factory power quick cut and standby automatic switch test.
u Operation mode The device is directly connected to a laptop or desktop computer for operation, which is convenient and fast, and has stable performance.
u New high-fidelity linear power amplifier The output end has always insisted on using high-fidelity, high-reliability modular linear power amplifiers instead of switching power amplifiers, with excellent performance. It will not produce high- and intermediate-frequency interference to the test site, and it ensures that the waveform is smooth and accurate in the whole process from large current to small current.
u The output part of the high-performance host adopts DSP control, with fast calculation speed, strong real-time digital signal processing ability, wide transmission frequency, and high-resolution D/A conversion control. The output waveform has high precision, low distortion and good linearity. Adopting a large number of advanced technology and precision components and materials, and carrying out a professional structural design, the device is small in size, light in weight, full-featured, easy to carry, and it can work after booting, and the flow test is very convenient.
u The software has powerful functions. It can complete various large-scale and complex calibration tasks with a high degree of automation. It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, and print reports online. The 6-phase current can facilitate the three-phase differential protection test, and the 12-phase output can be used for the automatic switching test of the factory power supply.
u It has an independent dedicated DC power output. There is a 110V and 220V dedicated adjustable DC power output.
u Complete interface The device has an RS232 port, which can communicate with computers and other external devices.
u 完善的自我保护功能 散热结构设计合理,硬件保护措施可靠完善,具有电源软启动功能,软件对故障进行自诊断以及输出闭锁等功能。
