KM1 Series
Multi-circuit Smart Power Monitor for back panel application
The KM1 platform enables the visualization of power consumption for back panel applications utilizing a master-slave concept. Up to four slave units can be connected to a master unit for simultaneous measurement of electric and non-electric parameters.
- Installation time consistently reduced.
- Mounting space reduced up to 24% compared to traditional monitoring products.
- Reduced number of devices: one platform can measure up to 36 circuits.
- Wiring reduced due to high speed innerbus communication and the power supply voltage from the master.
- Customizable platform for any applications
- Integrated Energy classification due to customizable internal thresholds
- High precision measurements even for currents below 5% of the nominal value.
- No VT required / Up to 7 pulse inputs accepted to collect also non electrical information
- Equipped with temperature input
- Free configuration tool KM//KE1 settings
- Dual system monitoring with one unit
