Omron KM-N2 and KM-N3 power monitors

Omron’s KM-N2 and KM-N3 power monitors offer a choice of both panel-mounted installation and DIN rail mounting for control panels.

The KM-N2 offers numerous advantages, such as high precision power measurements for inside control panels and a 9-digit, seven-segment display. The lettering used is large and white for added brightness and improved visibility. It accepts all international voltages and can function with either single- or three-phase connections using 2-, 3- or 4-wire circuits. Up to four standard current transformers can be connected to one unit.

The KM-N3 can precisely measure up to four circuits per unit with an IEC class of 0.5S. It features a large, easy-to-read white and green LCD for efficient visibility. Each power monitor can detect incorrect wiring connections and has special mechanisms for countering RF noise generated by inverters. RS485 is provided for communications to a central monitoring system, using Modbus RTU or CompoWay/F protocols.

The KM-N units are part of a series of black panel components that have a consistent look and feel. All panel components within the range are DIN rail mounted with a retentive clamp and have a footprint with a common height of 90 mm. This simplifies wiring, improves heat dissipation in the panel and removes dead space that occurs when adjacent components have varying heights.
