Multi Function Three Phase Programmable Electric Power Meter Digital LED Ammeter Voltmeter

Features: 1. Multi function power meter measurement for three phase voltage, current, active power, reactive power, power factor, grid frequency, active energy and reactive energy. 2. The signal can be directly input from the current and voltage transformer, and the input parameter ratio can be set by virtue of field programmability. 4. Good accuracy, strong stability, four buttons design, enables the instrument to achieve convenient and flexible use. 5. LCD digital display with high brightness presents three phase current or voltage value stimutaneously. 6. Premium ABS housing, excellent flame retardant properties, easy wiring. 7. Suitable for complete monitoring and management on the electrical parameters of various incoming loops and large capacity distribution output loops.
