This is easy to use and high accuracy relay testing kit. It can be used either for relay testing or for calibrating purpose.
S10A is a type of relay tester controlled by SCM (single chipset machine). It is portable, and easy to use. This tester can apply to the tests not only on operating value and operating time of AC/DC relays, but also on complex voltage blocking directional over current, zero sequence over current, low-frequency load shedding and other protection functions of low voltage line micro-processor based protection and whole group transmission of high voltage line micro-processor based protection, and on starting value, quick-break value, harmonic blocking value and manual synchronization of micro-processor based transformer differential protection.

Feature:
3*10A, 3*150V
