Product Detail

Electrical Power Quality Monitoring Equipment of Office Buildings for Energy Management Features: a.) Number of input channels Max. 24 channels/device (configurable as voltage or current input) b.) Measured values: - instantaneous value of voltage - instantaneous value of current c.) Calculated values - RMS voltage - RMS current - Apparent power - Active power - Reactive power (incl. capacitive/inductive indication) - Power factor d.) Averaging period for calculation: 1 min. e.) Built-in GSM module for realizing GPRS communication using different protocols (FTP, http, SNMP) with capability of SMS sending function, special warnings as required and defined by the customer f.) Built-in flash memory to prevent data loss (min. 16MB NOR flash) with microSD support g.) Large number of configurable alarm possibilities (power cut, overcurrent, overvoltage, capacitive/ inductive reactive energy is over the threshold value, etc.) according to the customers needs h.) Upload periods of calculated values to remote server: 10 min. 24 hrs. (configurable) i.) All parameters and the firmware can be updated remotely via the main wireless communication interface (GPRS/WiFi) j.) Protection - Voltage measurement overload (1 min.): 1.5 Vn - Voltage isolation: 2kV RMS (1 min., 50Hz) - Pulse overload capability: 1kV (8/20us) - Thermal protection - Housing: IP65 Optional functional: Saving time domain functions of current and voltage (all measured instantaneous values are stored) in case of power cut or other alarm events (min. 0.2s /10 period/, max. 5 sec, according to the sampling frequency and the number of input channels) Specification: - - - - Item | Parameter | Channels | A,B,C phase voltage A,B,C phase current | Measurement Range | Voltage 0100V ,220V.380V(customized).
