PowerBOX 4Kx | NETIO products a.s.

NETIO PowerBOX 4Kx is a LAN-enabled smart power strip with 4 outputs. Each output socket can be switched on or off individually over the web interface. Integration with third-party systems using various protocols (JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, ...) is easy thanks to the Open API. Electrical parameters (A, W, kWh, TPF) are measured with high accuracy at each output. With the secure NETIO Cloud service, the outputs can be controlled from anywhere.

 

 

NETIO PowerBOX 4Kx can be configured with a web browser (output control, measurements, timer settings, …). Individual outputs can be also controlled using the NETIO Cloud service, the mobile app or the Open API (http JSON/XML, SNMP, Modbus/TCP, Telnet, MQTT and more).

PowerBOX 4Kx is a smart LAN power socket in the form of a power extension cable. A RJ45 Ethernet cable is used to connect to the LAN.

The last letter of the model number indicates one of the three European socket types (4KF – most of EU (German Schuko), 4KE – French type, 4KG – British type). 

Electrical parameters (A, W, kWh, TPF, V, Hz) are measured with high accuracy at each output.

Each output can be switched on and off according to the current time and day of week. The time schedule can be different for each output.

 

Professional product

PowerBOX 4Kx can be used for light industrial applications. The product works in a wide temperature range, supports firmware upgrades over the web, remembers the last socket states before being powered off, allows defining a power-up delay for the outputs, and its relays switch at zero current (ZCS).

 

Typical applications

  1. Each electrical socket can be separately switched on or off from the product’s web interface.
  2. In addition to the other methods of control, each output can be controlled remotely with NETIO Cloud. For each output, NETIO Cloud displays the current consumption in kWh.
  3. The outputs can be metered and controlled with the Open API (JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, , ..)
  4. The NETIO power sockets device can work with various third-party programs and applications (Integration partners & NETIO Drivers).
  5. The power sockets can be controlled using the NETIO Mobile 2 (Android) as long as the app is connected to the same network, or with NETIO Cloud.
  6. Measurements of electrical parameters can be monitored in the web interface or with the Open APII.

 

Open API: Supported M2M protocols

One Open API protocol can be used at a time, chosen from among the supported M2M protocols:

The SNMP protocol can be always used in parallel to other protocols.

Regardless of the Open API used, the PowerBOX 4Kx can be always controlled from its web interface and from the NETIO Cloud service.

 

Customers can use the following ways to communicate with the device:

  1. WEB
  2. NETIO Cloud
  3. One chosen Open API protocol
  4. Mobile app over the LAN (via NETIO Cloud).

Industrial product quality

NETIO sockets are made with quality in mind. Each unit includes a set of supporting functions to ensure reliability and long service life of the product in real-life conditions.

 

ZCS (Zero Current Switching)

An important feature of NETIO PowerPDU 4C is ZCS (Zero Current Switching).

An important feature of NETIO PowerBOX 4Kx is ZCS (Zero Current Switching). ZCS controls the exact time when the mechanical relay contacts close and open. The relay contacts switch the output on or off when the current crosses the zero level. 

  • In the long run, ZCS support reduces the product failure rate due to internal relay damage.
  • Since the relay switches when the current waveform crosses the zero level, negative effects of inrush current are significantly reduced.
  • The ZCS and PowerUp delay functions reduce the chance of circuit breakers tripping when power is restored after an outage.
  • ZCS extends the lifetime of connected equipment; especially in case of frequent on/off switching of devices that are not designed for that (such as switching power supplies).

>> Glossary: More about ZCS

 

PowerUp state

For some applications, it is important to set the power socket state immediately after the device is powered on (or the power is restored after a failure). With some machines it is important to avoid momentary switch-on or switch-off. This parameter therefore defines the behavior of the 110/230V output power socket before the standard communication with a master system starts to work.

  • On
  • Off
  • LAST state restores the last state before the power was disconnected

 

PowerUp sequence (delay)

The PowerUp sequence function (delay) ensures that the 230V power output is switched on with a configurable delay (several seconds) after the power is restored. This can avoid circuit breaker tripping when power is restored after an outage.

The idea is to switch the outputs on one by one with a delay of a few seconds in between in order to avoid tripping the circuit breakers (see Inrush Current). We particularly recommend this function if there are two UPS or several LED lights in parallel in the same circuit.

 

>> Glossary: PowerUp state

 

Scheduler (timed switching of individual outlets)

With the Scheduler (timer) function, each output can be individually switched on or off at specified times and days of week. The switching times are easily configured in a graphical interface.

  • Each output can have its own schedule
  • When a schedule is active, outputs can be also controlled with NETIO Cloud, the web interface and Open API
  • Scheduler does not need an internet connection.
    However, it needs a time source – a NTP server. This can be provided over the internet or, for example, by a local ADSL / WiFi router.

 >> More information about Scheduler function

 

Mobile app

PowerBox 4Kx can be controlled over the local network using the NETIO Mobile 2 app (for Android mobile devices).

  • The mobile app can be used to control several devices and all their outputs.
  • The mobile device must be connected to the same LAN (via WiFi).
  • NETIO Mobile2 can scan the LAN and discover connected devices. WiFi connection to the LAN is required.

 

NETIO Mobile 2 is not available for iOS users. We recommend using third-party apps:

NETIO Cloud

The PowerBOX 4Kx smart power strip can be connected to NETIO Cloud. Control a hundred outputs from a single web screen! NETIO Cloud is an ideal solution for remote control and restarting. The NETIO Cloud service is provided for a fee and supports NETIO products.

  • All devices produced by the NETIO products company can be connected to NETIO Cloud.
  • Thanks to the included “Welcome credit”, the service can be used at no cost for the first 3 years.
  • Devices connected to the service can be controlled securely from anywhere over the Web (HTTPs).
  • NETIO Cloud can be used in parallel with another Open API protocol.
  • Communication with the Cloud service is secured (port 8883 - MQTTs - TLS).
  • NETIO Cloud uses a separate Open API (MQTTS protocol) to control all devices linked to a given user account).

FAQ

Expand all

Is it possible to specify in which state the output (a particular power socket) will be after power-up?

Yes. When the PowerBOX is powered up, all outputs are set according to the configured PowerUp state (On / Off / LAST value). The parameter can be set in the web interface in the detailed configuration for each output.

I forgot the password, how can I reset the product to factory defaults?

To reset the product to factory defaults, press and hold the button next to the RJ45 jack. Keep the button pressed and plug in the product. Still keep the button pressed. About 12 seconds after powering up, the yellow LED flashes 3 times and factory default settings are restored (Load to defaults).

 

For the current procedure, see the supplied QIG (Quick Installation Guide) for the product.
It is available for download at this page as well as included in the product package.

 

The NETIO Mobile app cannot find the NETIO PowerBOX 3Px.

For Android mobile devices, please upgrade to NETIO Mobile 2. For iOS mobile devices, a NETIO mobile app is not available yet. 

 

Can PowerBOX restart a device remotely?

Yes, the “Short OFF” command (accessible for instance in PowerBOX web interface) can switch the power to the device off for e.g. 5 seconds and then switch it on again automatically.

 

Typical applications include the remote restart function, where the user needs to send, over the Web or via the URL API, a command that momentarily switches the output off and then switches it back on. This is typically used to restart a LTE / WLAN modem; the PowerBOX controls the power to the modem. 

Can PowerBOX switch on an output at a specified time?

Yes, PowerBOX 4Kx supports the Scheduler function at each output.
More complex timing patterns can be also implemented in a master system.

 

 

Is it possible to control PowerBOX using an IoT cloud?

Yes. NETIO PowerBOX 4Kx includes an open API. We are continuously publishing ANxx (Application Notes) that describe how to connect the product to various third-party systems.

PowerBOX 4Kx also supports NETIO Cloud.
