The device tester machines -20

The device tester machines  -20M designed to test and control ampere-second characteristics of circuit breakers alternating current of industrial frequency in the range of 20A-20kA, measurement and recording of current and time passing through the circuit breaker, then AB. Can be used as a regulated source of alternating current to 20kA in power circuits low impedance.

For ensure the electrical safety of personnel, the output conductive circuit galvanically isolated from the mains supply.

Value the voltage on the output tires  -20, when fully open thyristor the key is not greater than 7V, which is beneficial to the contacts automatically switches in the cut-off is significantly reduced wear when multiple trials.
