L8833 series microcomputer relay protection tester manufacturer

L8833 series microcomputer relay protection tester

◆? Adopting 8.4-inch (800 × 600) TFT true color LCD display screen, advanced embedded system, high-speed DSP processor, and ultra large scale field programmable logic device FPGA
◆? The waveform fitting of 1448 points per week significantly improved the amplitude frequency characteristics and transient response of voltage and current of the testing system. Voltage transient response is 30us, current transient response is 20us (national standard 200us). Excellent transient response can better adapt to the development direction of new fast microcomputer protection
◆? Adopting a 20 bit serial port D/A digital to analog converter. Serial port D/A has better linearity and accuracy than parallel port D/A, and greatly improves the accuracy of small voltage and current signals.
The voltage source has short-circuit protection function, the current source has open circuit protection function and open circuit alarm function, the output has top cutting distortion detection function, misconnection determination alarm self-locking protection function, and output waveform dynamic monitoring and display function.
◆? By adopting unique heat dissipation components and temperature protection detection measures, the power amplifier has excellent stability and reliability under high current and long-term working conditions.
Using a 100M network card for data communication between the upper and lower computers, the real-time operation of the upper computer is high, and the software upgrade speed of the lower computer is fast. Upload test reports and remotely control and transmit data, making it faster and more convenient.
◆? Any interface can be operated using shortcut keys, with a friendly interface style and easy and fast operation.
◆? 40-220V/0.5A programmable auxiliary DC power supply, capable of providing separate working power to protection devices or other equipment. Ripple coefficient less than 0.1%, accuracy of 0.5%.
◆? Eight pairs of programmable input contacts, null contacts, and potential contacts that are mutually isolated are compatible, while four pairs of programmable output contacts are suitable for various wiring methods.
◆? Can set the interface color in the on-site lighting environment, providingz·uiExcellent observation effect.
◆? Equipped with a USB interface, it is convenient for on-site upgrades and downloading test reports using a USB drive.
◆? Equipped with external mouse and keyboard interfaces to adapt to user operating habits.
◆? It can be operated both online (computer) and offline, with complete offline operation functions.
◆? The upper computer testing software supports WINDOWS 2000/WINDOWS XP operating systems.
