Introduction:
The UHV-1200 Microcomputer Relay Protection Tester features a highly flexible combination of voltage and current outputs, supporting up to 6-phase voltage and 6-phase current channels. It allows users to configure various
output modes, such as the conventional 4-phase voltage and 3-phase current setup, 6-phase voltage output, or combined 6-phase and 12-phase output modes. This design ensures compatibility with traditional testing
methods and also facilitates advanced applications such as differential testing of three-phase transformers, fast bus transfer tests, and backup auto-reclosing verification.
The high-performance main unit employs DSP control in its output section, providing fast processing speeds, strong real-time digital signal processing capabilities, wide transmission bandwidth, and high-resolution D/A
conversion. This ensures high waveform precision, minimal distortion, and excellent linearity in output signals.
Through the application of advanced technologies, precision components, and materials—along with a professional structural design—the device achieves a compact and lightweight form factor without compromising
functionality. It is fully portable, easy to set up, and convenient for on-site or mobile testing applications.
