SFD-12 group screen analog circuit breaker

• SFD-12The intelligent analog circuit breaker is adopted by our company on the basis of the original analog circuit breaker51A new type of product developed from a microcontroller. Due to the use of a new type of microcontroller and program control, the accuracy of the entire machine has been improved. A 4U chassis can be used to form a simulated circuit breaker screen through a standard cabinet, adding0-220VAdjustable DC stabilized power supply greatly facilitates users and is a device for testing relay protection devices. This product has the characteristics of innovative design ideas, reliability and durability, convenient wiring, small size, and light weight. It is a commonly used equipment for testing relay protection devices. This product has the characteristics of innovative design ideas, reliability and durability, convenient wiring, small size, and light weight. It can be used in conjunction with various microcomputer based relay protection testing devices to complete the experimental and testing work of complete sets of relay protection devices for various voltage levels in the power system relay protection department, ensuring the integrity of the complete set of relay protection devices and improving the calibration quality of the devices.
