Intelligent controller characteristic test instrument

The utility model discloses an intelligent controller characteristic test instrument, which belongs to low-voltage electric appliance test equipment. The utility model aims at providing a test instrument which can simulate the change of a hollow mutual inductor of an intelligent controller, can generate three-phase signals with phase difference, can carry out timing on the delay protection, and can test the communication function. The intelligent controller characteristic test instrument consists of a digital-to-analogue conversion circuit (2), a processor circuit (8), four channel signal output circuits (3), a channel signal interface circuit (4), an intelligent controller operation state detection circuit (5), a communication interface circuit (6), an intelligent controller power supply, a control circuit (7) of the intelligent controller power supply, a keyboard circuit (9), a liquid crystal display circuit (10) and a power supply circuit (1). The utility model belongs to ideal equipment for testing the operation characteristic of the intelligent controller used for a universal circuit breaker.
