Introduction to JY-3/1 Voltage Relay (English)
The JY-3/1 voltage relay is a specialized monitoring device designed for DC power supply systems, featuring dual-circuit voltage detection capability. Its primary function involves supervising the control bus voltage (180-240V range) for both over-voltage and under-voltage conditions, while simultaneously monitoring the under-voltage status of auxiliary circuits (charging circuit and closing bus) within 180-360V range. The relay employs electromagnetic mechanism with transparent housing for operational visibility, allowing visual inspection of internal components and setting parameters. Equipped with adjustable potentiometers for voltage threshold customization and status indicator lights, it provides reliable performance in power system protection applications. The contact system demonstrates stable switching capacity up to 50W under 250V DC/5A conditions. This product suits various DC power distribution scenarios requiring precise voltage monitoring and protection functions. 81115
