A single Multi-Mon metering device can accommodate any combination of single- or multi-phase inputs for up to 36 current inputs. This permits configuration of up to three dozen single-phase, 18 two-phase, 12 three-phase, or other load combinations up to the device’s maximum input capability.
No external power supply is needed; Multi-Mon’s three phases and neutral are fed by the measured voltages. Measuring a compact 5.0” (127mm) H x 12.0” (304.8mm) W, Multi-Mon offers a choice of DIN rail mounting inside the branch circuit panel or an optional steel enclosure for mounting adjacent to the panel.
Available in delta and wye configurations, solid- and split-core current sensors are available from 100 to 1200A and are ordered separately due to the unit’s many possible current sensor and phase combinations. The standard communications protocol is Modbus RTU via RS-485 but Modbus TCP/IP via Ethernet is available optionally. The device is also compatible with E-Mon Energy™ software via EZ7 protocol for automatic meter reading, energy billing, load profiling and providing power quality information.
