KES Plus. KNX Electrical energy meter
Description
Zennio electrical energy meter for single-phase or three-phase systems. It can measure and notify in KNX system, not only the consumed or produced energy (KWh), but also the associated cost according to 6 different tariffs, the CO2 emissions, instant active and reactive power, power factor and other information related with the use of electric energy in the building. Alarms and notifications can be configured as warnings when power exceeds the limits established, for example, to disconnect low priority systems to reduce consumption. In addition, 10 logical functions are added to enlarge the versatility of the automations in KNX system.
Only compatible with Zennio Current Transformers: ZN1AC-CST60 and ZN1AC-CST120
- Suitable for 3-phase installations with neutral, or for three single-phase installations
- Power measurement (W or kW) and Energy with 3 registers
- Currency and CO2 emissions estimation registers
- KNX system clock synchronization is allowed
- Up to 6-tariff cost counters
- Total data saving on KNX bus failure
- Integrated KNX BCU (TP1-256)
- Dimensions 67 x 90 x 36 mm (2 DIN units)
- DIN rail mounting according to IEC 60715 TH35, with fixing 6 clamp
- Conformity with the CE, UKCA, RCM directives (marks on the right side)
