Product details
The main technical features of KF-6403 microcomputer relay protection tester are as follows:
Adopting high-performance DSP controller
The core main part adopts high-performance DSP control devices and high-resolution, high-precision D/A conversion devices, which have fast operation speed, strong real-time digital signal processing capability, high output signal accuracy, good stability, low distortion, and can ensure good linearity from small signal output to large signal output.
High power and high reliability switch amplification technology
The power output part adopts advanced switching amplifier technology, which has the characteristics of high reliability, high efficiency, small size, and high output power. The voltage amplifier reaches 0-125V/phase output, the current amplifier reaches 0-30A/phase output, and the maximum output power reaches 300VA/phase.
High output accuracy
The output of each analog channel of the KF-6403 tester can reach level 0.2, ensuring the accuracy of the test results.
■ Complete signal indication
All analog signals, input and output channels have corresponding indicator lights for displaying their usage status.
■ Complete self-protection function
The tester includes a complete self-protection function to ensure that it operates in a safe working state.
Modular design
Each component of the KF-6403 tester is independent of each other, especially each amplifier is an independent amplifier, which can be used for series or parallel output during use.
■ Automatic identification of potential and empty contacts
Provide eight sets of input channels, each of which can automatically recognize switch input signals with point positions and empty contacts.
