OEM Mingri Current-limiting Protector System Main Unit Supplier, Manufacturers

The current-limiting protector system main unit includes the CPU main control unit, alarm unit, communication unit, and display unit. By connecting to on-site current-limiting protectors, it can accurately receive power data transmitted from the current-limiting protectors. Through calculation and analysis, it determines whether values exceed standards. If values exceed thresholds, it triggers an audible and visual alarm. The current-limiting protector system main unit features a 6-inch LCD screen for displaying real-time on-site measurement data, performing historical data queries, system time settings, alarm parameter configurations, and other operations. The operation interface is simple and user-friendly. It adopts a wall-mounted installation method.

Main Components

1. Central Processing Unit (CPU) Functions as the "brain" of the system host, responsible for processing and analyzing all data received from field protectors, and making judgments and responses based on preset logic.

2. Communication Unit Responsible for data exchange with on-site current-limiting protectors. Common communication methods include RS485 bus, following protocols such as Modbus-RTU.

3. Display Unit Used to intuitively display system operation status, real-time data, alarm information, and historical records, facilitating viewing and operation by management personnel.

4. Alarm Unit When abnormalities are detected, it issues alerts through audible and visual means to draw management personnel's attention.
