STB8883S4-5/STB8883S8-5 Impulse Winding Tester

According to the output number of channels, STB8883 series is consist of 2 models: STB8883S8-5 and STB8883S4-5. STB8883S8-5 is the ideal product for measurements of multiphase coils. The 8 channel of STB8883S8-5 can be programmed and configured as voltage high-terminal, voltage low-terminal and OFF. Any combination of the configuration condition of the 8 channels and maximum 20 test procedures can be achieved. Also, it can test the coils successively in 8 channels. STB8883S4-5 is provided with 4 channels. It is especially developed on the basis of the 8 channels of STB8883S8-5 for customers who need less sweep channels. USB Host, RS232C, USB Device and LAN interface are provided in STB8883 series products for your quick save of the waveforms and remote control of the instrument.
