New generation ELC100-M intelligent combination low voltage reactive power measuring & control device
The ELC100-M is an integrated controller designed for reactive power compensation and power distribution monitoring. It combines data acquisition, communication, reactive power compensation, and grid parameter measurement and analysis into a single intelligent unit — controlled via a 4.3-inch HMI display with multi-language switching for better local user experience.
Two variants are available: ELC100-MZ, which uses RS485 communication to connect and control up to 32 EL-series combined low-voltage power capacitor compensation devices; and ELC100 -MD, which uses 12V voltage output control mode, supporting up to 24 control outputs.
Built for reliable industrial operation, the controller works across an ambient temperature range of -25°C to +55°C, up to 2000m altitude, and handles rated voltage of 220V ±20% with THDv ≤5%. Measurement accuracy is tight — voltage ≤±0.5%, current ≤±0.5%, reactive power ≤±2%, and power factor ≤±1% — ensuring precise compensation control.
ELC100 is an integrated controller for reactive power compensation and power distribution monitoring. It integrates data acquisition, communication, reactive power compensation, grid parameter measurement, and analysis.
If this product adopts RS485 communication method (ELC100 -Z), it can connect up to 32 pieces of HY series combined low voltage power capacitor compensation device or select 12V voltage output Control method (ELC100 -D), which can provide 12 or 16 steps Output (only one of the two methods can be selected)
