The Trumeter panel-mounted power meter is designed for use on mains circuits, potential transformers and current transformers. Its multi-measurement capability of active and reactive power makes it ideal for a wide range of power monitoring applications and one of the most flexible power meters for electrical monitoring. For single-, split- and 3-phase applications Measures Active (W), Reactive (VAr) and Apparent (VA) power Displays electrical parameters on large, backlit LCD display Features two independent opto-isolated digital outputs plus one analogue 4-20mA output Includes MODBUS® RTU communication as standard Provides clear indication of electrical circuit performance User-programmable scale and custom alarm messages display critical parameters and immediately alerts operators when a parameter is out of range Programmable Current Transformer (CT) and Potential Transformer (PT) ratios.
