1 unit, 2 roles: An energy saving monitor and power equipment meter
The PR720 is a Switch Board mount power monitor that accurately meets two needs: power equipment metering and energy saving monitoring.
It supports embedded installation in facilities that promote energy saving such as switchboards and generators in factories, buildings, offices, schools, and large stores.
- Easy-to-read bar graph display, and numeric display of any 4 elements simultaneously
- Multi-measurement centralizes conventional analog meters into a single unit
- Switchable from single-phase 2-wire to 3-phase 3-wire, with a universal design supply voltage that shares both AD and DC
- Demand monitoring function comes standard for efficient monitoring of power demand
- Communication function supports a variety of networks
* VJET signal conditioner is required for Ethernet connection.
*920 MHz wireless connection requires the UPM or UTA with a wireless function.

Details
Multimeter and 4 element simultaneous display
Display any 4 measuring elements and together on the LCD.
Simultaneously monitor measured values from three-phase circuits such as three-phase current/voltage. One unit can replace multiple meters, greatly reducing cost, space, and wiring.
Also measures reactive power, demand current, demand power, and other values, and comes with pulse output and communication output functions.
Improved visibility
Easy-to-read bar graph display, and numeric display of any 4 elements simultaneously.
Compatible with conventional 110-square mechanical meters. No need to redesign the mounting panel.
Power monitoring even more efficient with demand alarm and communication function
Increased power monitoring efficiency by condensing these functions into a single unit: watt hour integral pulse output, alarm output of demand current/demand power, RS-485 communication (Modbus), and others.
Universal
Power supply: 100–240 VAC and 80–143 VDC (both AC and DC uses)
Input specifications: Use parameters to switch between single-phase two-wire, single-phase three-wire, and three-phase three-wire
