Profile:
The device is directly connected to the external laptop or desktop computer for operation, convenient and fast, stable performance.
The output end has always adhered to the use of high-fidelity, high-reliability modular linear power amplifier, rather than switching power amplifier, good performance. It will not cause high and medium frequency interference to the test site, and ensure the smooth waveform from large current to small current.
Features:
High performance host: The output part is controlled by DSP, the operation speed is fast, the real-time digital signal processing ability is strong, the transmission frequency band is wide, and the high resolution D/A conversion is controlled. The output waveform precision is high, the distortion is small and the linearity is good. A large number of advanced technology and precision components and materials are used, and professional structural design is carried out, so the device is small in size, light in weight, full in function, easy to carry, can be started to work, and flow test is very convenient.
Strong software function: can complete a variety of large and complex calibration work with high degree of automation, can easily test and scan a variety of protection set values, fault playback, real-time storage of test data, display vector graphics, online printing reports, etc. Convenient for three-phase differential protection testing.
With independent dedicated DC power output: with one 110V and 220V dedicated DC power output.
Complete interface: The device has a USB communication port, which can communicate with computers and other external devices.
Perfect self-protection function: reasonable design of heat dissipation structure, reliable and perfect hardware protection measures, with power soft start function, software for fault self-diagnosis and output lock and other functions.
