The NETIO PowerDIN ZK3 combines a 3-channel energy meter and a 3-output power controller in one 6-module DIN-rail device. Meter and switch a 3-phase load — or three independent circuits — from the distribution board, and send the data to KNX, BMS or energy-management platforms over LAN or WiFi.

Key Features

  • 3 switched and metered outputs, max 16 A each, with Zero Current Switching (ZCS)
  • Works as a 3-phase 400 V (3 × 16 A) controller or as 3 independent 230 V / 16 A channels
  • Per-channel metering: A, W, Wh, True PF, phase shift, energy in/out, reverse energy, plus V and Hz — accuracy better than 1%
  • 2 digital inputs with S0 counters and 12 V supply; NETIO T1/TH1 sensors supported
  • LAN (RJ45) and 2.4 GHz WiFi
  • Scheduler, Ping & Power WatchDog and Conditions & Rules
  • Open API: JSON, XML, MQTT-flex, SNMP v1/v3, Modbus/TCP, Telnet, URL API, HTTP(S) Push

Integration & Control

Read measurements and control outputs from the built-in HTTPS web interface, the NETIO Mobile 2 app (iOS/Android) or the optional NETIO Cloud service (subscription). Feed energy data to KNX, BMS and energy dashboards over Modbus/TCP, MQTT, SNMP or HTTP/JSON.

Typical Applications

  • Sub-metering and control of 3-phase equipment
  • Energy monitoring of three separate circuits from one DIN device
  • Load shedding and peak-demand control in commercial panels
  • Adding energy data to KNX and BMS projects over Modbus/TCP

Certifications

No UL/NRTL listing stated by NETIO — verify local code requirements before specifying in US installations. Installation by a qualified electrician only.

FAQ

What is the difference between the ZK3 and the ZP3?
The ZK3 meters each channel with better than 1% accuracy and uses ZCS; the ZP3 switches only.

Can it integrate with KNX?
Yes — through a KNX gateway, logic module or visualization server that supports Modbus/TCP or MQTT.
