Typical applications

1. In IT, the smart PowerPDU 4KS is typically used to measure & distribute electricity in a 19" rack (cabinet) in a data center.
2. The connected appliances can be restarted from the web interface (each output can be switched on / off or power-cycled).
3. Powered devices can be restarted autonomously by PING or Power consumption Watchdog
4. The outputs can be controlled with the Open API (JSON, Modbus/TCP, SNMP, MQTT-flex, Telnet, ...)
5. The device can work with various 3^rd party programs and applications  (Open API)
6. The outputs of several NETIO products can be controlled using the NETIO Mobile 2 app (Andriod & iOS)
7. The outputs of multiple devices can be controlled centrally using the NETIO Cloud service (for a fee).

>> NETIO Usage cases

NETIO PowerPDU 4KS measures electrical parameters on 4 outputs + 1 total channel:
Measured values are displayed in the web administration interface and at the same time are accessible via Open API protocols. NETIO PowerPDU 4KS measures with accuracy better than 1%.

• Output 1
• Output 2
• Output 3
• Output 4
• All output together (power inlet)

A digital input (DI) can be used to control any of the outputs(s) or count S0 pulses. The DI can be connected to a button (dry contact) or used as a S0 pulse counter for reading energy consumption from an external electricity meter.

The DI state and the S0 counter value are shown in the web interface and accessible over Open API.

• Digital input (DI): 1x input (contact) + S0 counter (4 bytes)
• Power for DI: 12V power

NETIO Cloud

This product can be connected to the NETIO Cloud service (100 outputs can be controlled from 1 web screen). NETIO Cloud is an ideal solution for remote control and restarting.
The paid NETIO Cloud service is operated by NETIO products a.s. as a support for manufactured equipment.

• All products manufactured by NETIO products can be connected to NETIO Cloud.
• The user can control connected devices securely via the web from anywhere (HTTPs).
• The first 3 years are free connection to the service thanks to the "Welcome credit".
• NETIO Cloud can be used in parallel with other Open API protocols.
• Secure device communication to the Cloud service (port 8883 - MQTTs - TLS)
• NETIO Cloud has its own Open API, which can be used to control all devices in a specific user account (MQTTS protocol).

NETIO PDUs 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.

• Open M2M API
• Wide operating temperature range (–20°C to +65°C)
• PowerUp state – defined output state after power-up
• PowerUp delay (outputs switched on after a delay)
• Firmware upgradeable over the web, backwards compatibility
• IOC -  Independent Output Control
• ZCS – Zero Current Switching
• Outputs can be switched on/off for a short (configurable) time

An important feature of NETIO PowerPDU 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

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

Delay sequence when switching outputs on

After a power outage, some electrical appliances can be switched on with a delay to avoid overloading and tripping circuit breakers. With the PowerPDU 4KS, use these parameters: “Power-Up state” = ON / LAST, and “Output PowerUp interval” = power-up delay before switching that particular output on.

>> Glossary: PowerUp state

• Each output can have its own schedule
• When a schedule is active, outputs can still be controlled with NETIO Cloud, the web interface and Open API
• Scheduler functionality can be enabled/disabled (not edited) for each output from the NETIO Mobile 2 app.
   
• Scheduler does not need an internet connection. However, a time source is needed – provided over the internet or, for example, by a local ADSL / WiFi router.
• For special usage the Scheduler can be combined with PAB (Power Analyze Blocks):
  • Switching time is based on current sunrise/sunset based on your location
  • Whatever happend, defined output can be switched off on defined time (midnight for example).
  • Ask for more..

WatchDog Ping + Power

PowerPDU 4KS is equipped with WatchDog PING (IP WatchDog) and WatchDog Power consumption (PAB).

• WatchDog Ping continuously monitors whether a given process or a part of a system work as they should. If not, the WatchDog restarts the process. Can be used for all 4 outputs.
   
• WatchDog Power is "Condition" & "Action" (PAB - Power Analysis Block & Rules) based autonomous system. It continuously monitors current (energy) of monitored device powered from any metered power output of NETIO PDU device. Can be used for all 4 outputs.

PowerPDU 4KS / 4PS / 4C comparison

“PowerPDU” designation (form factor) means that the product is intended for IT environment for installation in a 19” cabinet.

Accessories are available from the manufacturer to mount one 4C / 4PS unit (RM1) or two units side-by-side (RM2) into 1U of space in a 19” rack/cabinet. Other accessories allow mounting the product vertically, to the back, or to the side of the cabinet.
