Outline

0MPM 330 Power Meter is a digital type power meter that can accurately measure 3-phase electricity.
0A high performance exclusive DSP chip and MPU are adopted for accurate measurement; interface with the system is possible using the embedded communication function; the 3-row high luminance FND display provides high visibility and displays the current measurements in real-time; and the product can be easily installed in place of the existing analog type watt-hour meter as the external shapes are same. Three-phase and single-phase can be easily converted, and the product is galvanic isolation treated to have strong resistance to external surge and noise.

Functions and features

• High speed and high accuracy are ensured by adopting a DSP chip exclusively for power measurement.
• The stability of the product is ensured by embedding switching power.
• Diverse information is displayed and high visibility is provided by embedding 3-row high luminance FND and LED.
• Three-phase and single-phase can be simply converted.
• Galvanic isolation treatment is done to cope with external noise and surge.
• Values can be changed by directly changing them on the front panel (CT/PT ratio, etc.)
• One-to-one replacement is possible as the external shape is same as that of the existing analog type measuring instrument.
• CE certification
