WM20AV63H Carlo Gavazzi Power analyzer for three-phase systems

WM20 is a modular power analyzer for single-, two- and three-phase systems. It is made up of a maximum of three components: the main unit that displays measurements on the LCD display and manages two alarms, and two accessory modules, one with digital 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 communication module allows you configure the analyzer and transmit data using a different communication protocol according to the version.  System and phase variables (4 x 3 digits): V L-L, V L-N, A, W/var/VA, PF, Hz Active and reactive imported and exported energy meters (10 digits) Calculate the average and maximum system and phase power values Calculate current and voltage THD (total harmonic distortions) up to the 32nd harmonic Calculate load operating hours Rotating pages function Auxiliary power supply Two virtual alarms Backlit LCD display and touch keypad Optical port Detachable terminals Sealable terminal caps Configuration via keypad or UCS configuration software Filter to stabilize displayed measurements
