Brief introduction
The GF-LCS-DX102X dual lamp controller can achieve dual lamp switching, dual lamp dimming, dual lamp fault detection, and can be combined with the street lamp centralized controller GF-LCS8008-CLC to form a complete dual lamp control system, which is particularly suitable for municipal street lamp applications. The core chip adopts the power line carrier chip independently developed by Beijing Jiafuxin Technology Co., Ltd., combined with professional hardware and software design, making the product easy to implement, wiring free, reliable in operation, easy to maintain, and equipped with a metering module that can measure the voltage, current, power, energy and other data of lamps. It is a high-performance energy-saving street lamp product specially developed to adapt to the Chinese power grid environment. The GF-LCS-DX102X series single lamp controller mainly includes four models: GF-LCS-DL102, GF-LCS-DL102T, GF-LCS-DH102, and GF-LCS-DH102T. The corresponding light sources and functions are shown in the table below.

3、 Main functions
1. Power line carrier communication
The dual lamp controller integrates a power carrier communication module internally, which does not require wiring and can communicate and control with the central controller through existing cables.

Dual light switch control
Integrated with two switches (relays), each supporting on/off control of 1KW lamp load.

3 Dual Lamp Dimming Control
Provide two PWM or two 0-10V analog outputs, which can be used to dim electronic ballasts/LED street lights, etc; Provide two constant power outputs, which can be used to dim inductive high-pressure sodium lamps, etc.

4 Measurement functions
The dual lamp controller contains two current and voltage measurement circuits inside, which collect real-time data such as current and voltage, monitor the working condition of the dual lamp controller load, and can read the load's voltage, current, power (active, reactive, total power), and active energy at any time.

5 alarm functions
Powerful exception handling mechanism, supporting overload alarm, lighting failure alarm, and abnormal light off alarm; Specific nodes can be configured as anti-theft terminals with cable anti-theft function.

6 Protection functions
It has overcurrent protection and overvoltage protection functions.

4、 Technical indicators

5、 Main features
1. Easy to construct and maintain
The dual lamp controller adopts power line carrier technology and street lamp centralized controller communication, relying on existing power cables to achieve communication and control, with simple construction and convenient maintenance.

2 Powerful Exception Handling Mechanisms
Powerful exception handling mechanism, supporting overload alarm, light on underload alarm, and light off abnormal alarm, can accurately determine the fault status of each lamp.

Strong anti-interference ability
The design and production of the controller follow the ISO9000 quality management system. The product adopts circuit design technologies such as anti reverse connection, anti overvoltage, anti current, and optocoupler isolation, which can withstand harsh on-site environmental tests and repeated operation and debugging by on-site personnel.

4 Waterproof and anti-corrosion
The dual lamp controller adopts an aluminum alloy shell and is filled with epoxy resin sealant inside. It has excellent waterproof and anti-corrosion performance, with a protection level of up to IP65, and can adapt to harsh environments such as ultra-high temperature, high humidity and high salt.
