1. Summary
CPL8100A/B is a kind of current probe that can measure both DC and AC current up to 100A (70.7Arms). The band width of CPL8100A is 600 kHz (-3dB), and the band width of CPL8100B is 2MHz (-3dB).CPL8100 series provide two range option of 10A and 100A, the users may choose the correct range according to the current value. The auto zero function make it easy for the users to operate, and it also has power and low voltage indicator as well as overload sound alert. The probe can be powered by battery or external power supply, which makes the measurement a lot more convenient. With standard BNC output port, the probe can connect to any oscilloscope, and it can also connect to multimeter with BNC-banana plug. The CPL8100 series is usually used in power supply , motor drive and power supply.
