Power Analyzer

Product Details:

Three-phase smart power analyzer with built-in advanced configuration system and LCD data displaying. Particularly recommended for the measurement of the main electrical variables. WM30 is based on a modular housing for panel mounting with IP65 (front) protection degree. Moreover, the analyzer can be provided with digital outputs that can be either for pulse proportional to the active and reactive energy being measured or/and for alarm outputs. The instrument can be equipped with the following modules: RS485/RS232, Ethernet, BACnet-IP or BACnet MS/TP communication ports, pulse and alarm outputs. Parameters programming and data reading can be easily performed by means of WM3040 Soft.

Product Details:

Carlo Gavazzi Energy Management systems provide information so that operators can identify consumption trends and take corrective actions. Analysing the power profile operators can also aggregate loads and so negotiate more favorable terms with the utility company. Real-time power consumption monitoring also allows a site manager to anticipate overload conditions that would, for example, trip a circuit breaker. Alarm thresholds can be set to warn managers if preset limits are reached. Carlo Gavazzi Energy Management equipment meets the requirements of commercial buildings, Industry and production facilities, services and infrastructures.

Features:

• Wide range of power quality meters, energy meters, and transducers
• Fast installation, programming and display information reading
• Easy communications with PLC or PC control systems to provide plant-wide monitoring
