CGDL-12 type automatic controller (for thyristor switching control) Overview CGDL-12 controller is for the grid impact shock loads generated by the reactive power reactive power compensation controller dedicated it and fast with non-contact switch, can respond quickly to rapidly changing load response, the system's real-time power factor of stability in the user-specified range. voltage can be stabilized by the end of the grid and improve power quality, improve system stability , improving transmission capacity, reduce power consumption grid, increase the output power and operating economic transformer features: 1, fast response, never played constantly changing power output step of compensating control signal used for the longest time 11mS 2, using the fast Fourier decomposition algorithm to extract only the fundamental reactive power, power factor as the switching control of physical, so it is not sensitive to harmonics. 3, to provide 12 kinds of capacitor capacity encoding method, the greatest degree of adaptation rapid changes in the field of reactive power. 4, to provide PT, CT, metering mode control parameters, users can modify these parameters can be adapted to single-phase, 3-phase 3-wire, 3-phase 4-wire and different voltage levels different current levels of grid system adaptability. 5, to provide a capacitor capacity monitoring function allows compensation device is not running under a fault condition, the fault can be avoided expansion. 6, all control parameters are password protected so that only those who know the password can modify these parameters. 7 providing harmonic protection, undervoltage overvoltage protection. 8, to provide remote communication capabilities, users can use this function remotely modify the control parameters, remote control capacitor switching and remote monitoring and abnormal events are sent to the user-specified mailbox . 9 or mobile phone and other functions, provides manual switching function power capacitor bank, easy installation 10 provides humanized operation interface, intuitive and simple operation Technical Parameters: System: 3-phase 4-wire; 3-phase 3-wire;. single-phase system supply voltage: AC 220V -15% -> +20% Frequency :45-65Hz signal current :0-5A AC input voltage signal: AC 100V Note: Using a higher level of voltage applied voltage transformer voltage built-in virtualization Transformer 1:220 / 100 Note: For 220V input voltage signal can be directly built-in virtual voltage transformer 2:380 / 100 Note: For 380V voltage signal input current can be directly input impedance: <0.05 ohm input impedance voltage: 100V 390K ohm impedance input voltage: 220V-380V 780K ohm Control: active switch signal -12VDC/10mA / road fastest speed of response: 11mS (50Hz) :1-12 road control loop operating temperature range: -20 ℃ - +70 ℃ Communication port: RS485 communication protocol: MODBUS RTU Display: 4 red LED Installation: flush mounted, fixed attachment Dimensions: 140mm * 138.5mm * 138.5mm (L * W * H) Hole size: 140mm * 140mm (Note: the physical dimensions of 138.5mm * 138.5mm) with communication functions hole size: 139 * 139mm Model Selection table control ones opening size Note CGDL-JKW-8 8 138 * 138 digital display CGDL-JKW-12S 12138 * 138 digital display CGDL-JKW-16 16 138 * 138 digital display CGDL-JKW-18 18 139 * 139 with communication CGDL-12 12 113 * 113 LCD * with communication CGDL-16S 16 113 * 113 LCD show
