WM30 Power analyzer for three-phase systems Benefits Description WM30 is a modular power analyzer for single-, two- and three-phase systems. It is made up of a maximum of four components: the main unit that displays measurements on the LCD display and manages 4 alarms, and three accessory modules, one with digital outputs, one with analogue outputs and the other for communication. The digital output module associates alarms with static or relay outputs and/or transmits pulses proportional to energy consumption. The analogue output module associates 0-20 mA or 0-10 V outputs to measured variables. The communication module allows you configure the analyzer and transmit data using a different communication protocol according to the version. • Clarity. The wide backlit LCD display clearly shows the measurements and the configuration parameter values. • Simplicity. An optical port is available for quick analyzer configuration using OptoProg (CARLO GAVAZZI). • Specific software. WM30 can be configured and measurements viewed from UCS configuration software (CARLO GAVAZZI). The software and subsequent updates are free. • Scalability. Three accessory modules can be added to WM30 according to need. This way, the analyzer extends its control capacities and communicates data remotely. • Communication flexibility. The communication module is available in Modbus RTU, Modbus TCP/IP, BACnet IP, BACnet MS/TP and Profibus DP V0 versions. • Fast installation. WM30 and accessory modules are all equipped with detachable terminals. Modules can be quickly installed via the specifically designed fast coupling pins. • Tamper-proof. WM30 configuration access can be locked. Terminals and accessory modules can be sealed. Main functions • • • • • • • Measure main electrical variables and voltage and current harmonic distortions Measure active and reactive energy Measure load operating hours Manage up to 4 alarms Manage two digital outputs (via optional accessory module) Manage two analogue outputs (via optional accessory module) Transmit data to other systems (via optional accessory module) 28/04/2022 WM30 DS ENG CARLO GAVAZZI Controls SpA 1 WM30 Applications WM30 can be installed in any switchboard to control energy consumption, main electrical variables and harmonic distortion. In automation, WM30can use the communication module with Profibus protocol to both communicate data on consumption to supervision systems and manage them independently if installed on a machine. In building, WM30can be installed in existent architectures using the communication module with BACnet protocol (on RS485 or Ethernet).
