Audited Supplier Relay protection tester/Relay protection comprehensive test device
Main feature
Flexible combination of voltage and current output: the model has a standard 4-phase voltage and 3-phase current output, which can be easily carried out a variety of combined outputs for various types of protection tests. Each phase voltage can output 120V, current three and can output 120A, the fourth phase voltage Ux is a multi-function voltage item, can be set to 4 kinds of 3U0 or check the voltage period, or a voltage value of the case output.
Easy to operate: the device panel is equipped with trackball mouse, optimized keyboard and large-screen TFT LCD display, built-in Chinese Windows platform operating software. Boot can be used, easy to operate.
Dual operation mode: In addition to stand-alone operation, the device can also be connected to an external laptop or desktop computer for operation, the two ways of function is consistent, the real dual operation mode.
New high-fidelity linear power amplifier: The output has always adhered to the use of high-fidelity, high-reliability modular linear power amplifier, rather than switching power amplifier, excellent 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.
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. The device is small in size, light in weight, full in function, easy to carry, can be started to work, flow test is very convenient.
Powerful software: 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.
With independent dedicated DC power output: The device has one 110V and 220V dedicated adjustable DC power output.
Complete interface: the device panel has its own keyboard and mouse, which can be operated on a single machine, or external keyboard and mouse can be operated through the keyboard and mouse interface; It also comes with two USB ports and RS232 ports for communication 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.
Light and small highly integrated single machine and integrated structure: a large number of high-tech carefully designed ultra-light small structure, making the whole machine small and lightweight.
