PowerPDU 4KS

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.

PowerPDU 4KS can be controlled over the local network using the NETIO Mobile 2

• Device can be controlled:
  • on the same LAN (Mobile device is connected to WiFi)
  • Via NETIO Cloud (Mobile device have to be connected to internet)
     
• The mobile app can be used to control several PDU units and all their outputs
• NETIO Mobile2 can scan the LAN and discover connected devices. WiFi connection to the LAN is required.

For the moment, NETIO Mobile 2 application is not available for iOS users. We recommend using third party apps:

• AN39 NETIO and third-party mobile apps for iPhone – iOS (URL API, Telnet, Modbus)
• AN38 NETIO and third-party mobile apps for Android (URL API, Telnet, Modbus)

The switching of outlets can be time-controlled by the Scheduler with a graphical interface. Switching on/off at specific times can be easily configured.

• Each output can have its own schedule, according which the output is switched
• While Scheduler (calendar) is running, the output can be controlled from NETIO Cloud, web interface or Open API
• The Scheduler does not require an internet connection (requires a time source – NTP server – for example a local ADSL / WiFi router)

“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.
