HS874 intelligent analog circuit breaker (with power supply)
Technical Parameters
1. Overview
HS874 intelligent analog circuit breaker is a new product developed by our company based on the original analog circuit breaker using 51 single-chip microcomputer. Because the new single-chip microcomputer adopts program control, the accuracy of the whole machine is improved. The addition of 0-220V adjustable DC regulated power supply greatly facilitates users and is an indispensable equipment for testing relay protection devices. This product has the characteristics of novel design, reliable and durable, convenient wiring, small size and light weight. It is a common equipment for testing relay protection devices. This product has the characteristics of novel design, reliable and durable, convenient wiring, small size and light weight. It is used in conjunction with various types of microcomputer-type relay protection test devices to complete the experiment and detection of complete sets of relay protection devices of various voltage levels in the relay protection department of the power system, ensure the integrity of the complete set of relay protection devices, and improve the calibration quality of the device.
