The APM Power Meter is a digital panel meter for single-phase, split-phase and three-phase applications. The user-programmable power meter offers a dynamic three-color display and Modbus connectivity in a compact size.


Trumeter Power Meter

This panel-mounted power meter is designed for use on mains circuits up to 300VAC LN / 600VAC LL and 6A as well as Potential Transformers (PT) supported up to 10,000V and Current Transformers (CT) up to 10,000A. 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.



• Modbus RTU connectivity plus digital and analog outputs as standard for easy system integration.
• Fits into smaller and shallower enclosures than its competitors at just 72mm square and 74mm deep.
• Features a three-color dynamic LCD screen that instantly alerts operators to alarm conditions.
• Supports configuration of a wide range of parameters via software to minimize setup time.
