Netio PowerPDU 8QS, 8x IEC-320 C13 switched and metered PDU

Features of the NETIO PowerPDU 8QS

ZVS (Zero Voltage Switching)

ZVS (Zero Voltage Switching) means switching the 110/230VAC output when the immediate voltage is zero.
ZVS is a good solution for switching on/off devices such as switching power supplies.
ZVS is not suitable for controlling inductive loads (transformers or motors), as it increases the probability of relay damage when such types of loads are frequently switched on/off.
NETIO products without energy metering support ZVS (Zero Voltage Switching) when switching 110/230V relay outputs.
ZVS is sufficient relay switching technology for most load types, such as switching power supplies in IT solutions.



IOC (Independent Output Control)

Independent Output Control function of the NETIO device uses an independent system that ensures a stable operation of the output even if the main system is being restarted, updated, or is booting.
Thanks to IOC, the controlled output can power devices that, for technical reasons, must be powered without interruption (such as servers). The output control is completely independent from the WiFi or LAN communication subsystem.



PowerUp State

The PowerUp State parameter (sometimes also called Cold start) defines the behavior of the 110/230V power output during the first milliseconds to seconds after powering up the device, before the LAN/WiFi communication with a master system is established.
For some applications, it is important to set the correct state of a power output immediately after power is turned on (or restored). With servers in particular it is important to avoid undesired momentary switching.
Possible settings for NETIO device
• On
• Off
• LAST state restores the last state before the power was disconnected



Electrical measurements – only PowerPDU 8QS

PowerPDU 8QS measures relevant electrical parameters on the first Output and all outputs together.
