Technical Parameters
1. Adopts 8.4-inch (800×600) TFT true color LCD display, advanced embedded system and high-speed DSP processor, and ultra-large-scale field programmable logic device FPGA
2. Waveform fitting of up to 1448 points per cycle significantly improves the amplitude-frequency characteristics and voltage/current transient response of the test system. Voltage transient response 30us, current transient response 20us (national standard 200us). Excellent transient response better adapts to the development direction of new fast microcomputer protection.
3. Uses 20-bit serial D/A converter. Serial D/A has better linearity and accuracy than parallel D/A, greatly improving the accuracy of small voltage and current signals.
4. Voltage source has short-circuit protection, current source has open-circuit protection and open-circuit alarm, output has clipping distortion detection, miswiring judgment alarm self-locking protection, and output waveform dynamic monitoring and display.
5. Unique heat dissipation components and temperature protection detection measures ensure excellent stability and reliability of the power amplifier under high current and long-term operation.
6. Uses 100M network card for data communication between upper and lower computers, high real-time performance of upper computer operation, fast software upgrade of lower computer. Test report upload, remote control, and remote data transmission are faster and more convenient.
7. Any interface can be operated with shortcut keys, friendly interface style, simple and fast operation.
40-220V/0.5A programmable auxiliary DC power supply can independently provide working power for protection devices or other equipment. Ripple coefficient less than 0.1%, accuracy 0.5%.
8. Eight pairs of mutually isolated programmable input contacts, compatible with dry contacts and potential contacts, four pairs of programmable output contacts, suitable for various wiring methods.
9. Interface color can be set according to on-site lighting conditions, providing optimal viewing effect.
10. USB interface is provided for convenient on-site upgrades and downloading test reports via U disk.
11. External mouse and keyboard interfaces are provided to adapt to user operating habits.
12. Can operate both online (with computer) and offline, with complete offline operation functions.
13. Upper computer test software supports WINDOWS 2000/WINDOWS XP operating systems.
