ZENNIO ZIO-KESP KES Plus - KNX electricity meter

Zennio's KES Plus is an electrical energy meter designed for single-phase or three-phase systems, ideal for energy management and monitoring in KNX systems.

Key Features

• Support for 50 and 60 Hz frequencies.
• Compatibility with single-phase and three-phase systems.
• 3 independent input channels to monitor up to three independent single-phase lines or a three-phase line.
• Measurement of power and energy, cost and CO2 emissions in up to 3 registers (one total and two partial).
• Up to 6 tariff meters for estimating the cost of energy consumption.
• 4 alarms for excess power and low power.
• Up to 15 notifications of different situations: overvoltage, undervoltage, excess consumption, energy generation, economic cost, CO2 emissions.

Monitoring and Notification Features

The KES Plus allows you to configure alarms and notifications such as alerts when power exceeds established limits, for example to disconnect low priority systems and reduce consumption.

Measurement Parameters

• Power measurement unit [W, VaR/kW, kVar].
• Energy measurement unit [W·h, Var·h/kW·h, Kvar·h].
• Nominal power per phase [[1... 30000] [W]/[1... 30] [kW]].
• CO2 ratio [1... 30... 255]: hundredths of a kilogram of CO2 emitted per unit of consumption (0.01 kgCO2/kWh).

Logical Functions and Synchronization

The device includes 10 customizable, multi-operation logic functions, as well as synchronization with an external KNX clock and periodic “still-alive” notifications.

Configuring and Sending Data

• Sending mode for energy [Disabled/Periodic/With change in value/Periodic and with change in value].
• Period between cyclical mailings [[10... 255] [s]/[1... 255] [min/h]].
• Minimum time between consecutive submissions [10... 255] seconds.
• Minimum value change required to send the next value [[10... 30000] [W]/[1... 30] [kW]].

The KES Plus connects to the KNX bus through the connection terminals and requires the use of Zennio current transformers (ZN1AC-CST60 and ZN1AC-CST120).
