The 11800 chroma ripple current tester is a precise tester designed for lifetime testing of electrolytic capacitors. It has a digital control function for constant ripple current output and constant peak voltage output (Vpeak = Vdc + Vac_peak). This makes lifetime testing of electrolytic capacitors easier and more reliable. And the Chroma 11800 uses excellent output gain technology to reduce power consumption and internal temperature rise. For long-term testing applications, it can reduce the cost of electricity and it runs with high stability. The Chroma 11800 is exactly the right solution for testing an electrolytic quality assessment.
