| Product Introduction |
GC-DB100 is suitable for AC380V and AC660V low-voltage systems. It adopts a powerful 32-bit processor and advanced 24 bit A/D conversion technology. It integrates measurement, protection, network communication and other functions, and can provide comprehensive protection and control for three-phase asynchronous motors.
This product adopts a modular integrated structure design, with a small volume, compact structure, and easy installation, especially suitable for switchgear, drawer cabinets, and operation boxes.
It can replace traditional molded case circuit breakers, thermal relays, ammeters, current transformers, various signal lights, a large number of intermediate relays and time relays, transmitters, PLCs and other components. It is an ideal product for motor protection in industries such as petroleum, chemical, coal, power, metallurgy, municipal, etc.
| Product Features |
Advanced high-performance industrial grade microprocessors with strong data processing and information storage capabilities, high reliability, and fast operating speed;
High brightness LED display, user-friendly buttons, easy for users to manually set parameters;
Adopting advanced storage technology, the set parameters can still be saved after power failure;
Protection function: The device has multiple built-in protections, which can be easily selected to enable or disable protection, alarm or trip;
The product can expand the "leakage protection" function and detect the leakage status of the motor circuit;
Equipped with event recording function, it can query the latest event record through the panel, facilitating fault analysis of the cause of the event;
Equipped with remote communication function: using RS485 interface and Modbus RTU protocol, measurement and control information, switch status, protection parameters, etc. can be uploaded to the background monitoring host to form a motor control center, achieving centralized management from a distance.
Wide power input function: applicable range of working power supply, AC85V~264V、DC110V~340。
Commonly used for AC or DC on-site power input.
