RK9920-16C/RK9920-32C AC and DC withstand voltage insulation tester
Product description
This series of program-controlled withstand voltage testers are high-performance safety testers designed with high-speed MCU and large-scale digital circuits. The size of the output voltage, the rise and fall of the output voltage. The frequency of the output voltage is safely controlled by MCU, which can display the breakdown current and voltage value in real time, and has software calibration function. It is equipped with PLC interface, RS232C, RS485, USB device, and USB Host interface, which can easily form a comprehensive test system with a computer or PLC. . It can quickly and accurately conduct comprehensive safety measurements on household appliances, instruments, lighting appliances, electric heating appliances, computers, and information equipment.
Application field
Comprehensive safety measurement for automation system testing, household appliances, transformers, motors, electrical equipment, electric heating appliances, lighting industry, new energy vehicles, and electronic components
Performance characteristics
1. 480×272 dots, 5-inch TFT-LCD display
2. Fast discharge and arc detection function
