Current Relay Test Kit Micro Computer Protection Relay Tester Single Phase Relay Tester

Flexible combination of voltage and current output: With standard 4-phase voltage and 3-phase current output, it can conveniently perform various combination outputs for various types of protection tests. Each phase voltage can output 120V, and the current triple can output 120A. The fourth phase voltage Ux is a multifunctional voltage item, which can be set to four types of 3U0 or detect the same voltage, or output in the case of a certain voltage value.
Single machine operation convenience: The device panel is equipped with a trackball mouse, optimized keyboard, and a large screen TFT LCD display, with built-in Chinese Windows platform operation software. Ready to use upon startup, easy and fast to operate.
Dual operation mode: In addition to single machine operation, the device can also be connected to a laptop or desktop computer for operation. The two modes have the same function and are truly a complete dual operation mode.
New type of high fidelity linear power amplifier: The output end has always adhered to the use of high fidelity and high reliability modular linear power amplifiers, rather than switch type power amplifiers, with good performance. It will not cause high or intermediate frequency interference on the test site, and ensures excellent waveform smoothness and accuracy from large to small currents.
High performance host: The output part is controlled by DSP, with fast computation speed, strong real-time digital signal processing ability, wide transmission frequency band, and control of high-resolution D/A conversion. The output waveform has high accuracy, low distortion, and good linearity. A large number of precision component materials have been used and specialized structural design has been carried out, resulting in a small volume, light weight, full functionality, and convenient portability of the device. It can work immediately upon startup, and the flow test is very convenient.
Strong software functionality: It can complete various large-scale and complex verification tasks with high automation level, conveniently test and scan various protection settings, perform fault replay, store test data in real-time, display vector maps, print reports online, etc.
Equipped with dedicated DC power output: The device is equipped with a dedicated adjustable 110V and 220V DC power output.
Rich contacts: with 8 contact inputs and 4 empty contact outputs. The input contact is compatible with the null contact and the 0-250V potential contact, which can be intelligently and automatically recognized.
Complete interface: The device panel comes with a built-in keyboard and mouse, which can be operated on a standalone basis. It can also be operated through external keyboard and mouse interfaces; It also comes with two USB ports and RS232 ports, which can communicate with computers and other external devices.
Perfect self-protection function: Reasonable heat dissipation structure design, reliable and complete hardware protection measures, with power soft start function, software self diagnosis of faults, and output locking function.
Lightweight and highly integrated single machine and integrated structure: It adopts a large number of high-tech and carefully designed lightweight structures, making the entire machine small and lightweight.
