YNAS-500 DC Switch Ampere Second Characteristics Tester

Based on the current situation of testing the ampere second characteristics of DC protection devices, our company has launched a DC circuit breaker ampere second characteristic testing system that is suitable for on-site use in substations, easy to carry, and highly automated. It can provide a testing method for the action characteristics of DC protection devices for operation and maintenance departments, verify the action characteristics and level coordination of DC protection devices, in order to improve the reliability of DC system operation and ensure the reliable operation of the power grid.
YNAS-500 DC Switch Ampere Second Characteristics TesterSuitable for ampere second characteristic testing of rated current 1A~500A DC circuit breakers, and can be used for ampere second characteristic testing of 6A~150A DC fuses.
