overview

The YNCS-910H universal protection and measurement device is a digital multifunctional relay that integrates multiple functions such as protection, measurement, monitoring, control, human-machine interface, and communication. It is the most universal and widely used protection and measurement device, which can be applied to the main or back protection of various electrical equipment and lines in non directly grounded power grids with voltage levels below 110kV.

Main features of the device

The working power supply is compatible with 85-264V AC and DC power supplies, with a powerful 32-bit embedded control system, an all aluminum alloy chassis, and a standard circuit breaker operation circuit. (Note that the operating circuit voltage needs to be specified before ordering)
