Zero Current Switching (ZCS) ensures that a relay contact is closed at the zero crossing and opened at the precise moment when zero current flows through it. This has a number of advantages for smart power devices using relay switching techniques. With less potential harm from inrush currents, there is less wear on the relay itself and greater protection for connected switch mode power supplies (SMPS). There is also significantly reduced electromagnetic interference from repeated switching On/Off. Opening a relay contact when the current is zero is important for inductive loads (motors, transformers) but less so for capacitive loads including switch mode power supplies (SMPS) of the type found in computers, servers and IT network peripherals.
Smart Power Monitoring and Control Devices
A range of smart power monitoring and control devices including power strips, extension leads and power distribution units (PDUs) with smart management features that can be used to monitor a range of metrics including Amps, Volts, Energy Usage and Power Factor either via Ethernet or WiFi. With smart power control devices, individual sockets can be monitored and set for scheduled power-ups/shutdowns and remote reboots. Smart power strips and power cables can be used in a range of applications including remote/home worker computer systems, audio-visual (AV) systems, IT networks, server rooms, datacentres, Internet of Things (IoT), fridge/freezer controls, scientific and test laboratories, and Industrial manufacturing sites. The Smart Power Plugs (BS1363 UK and IEC32) feature WiFi control and management features via a web interface.

PowerBox 3P Smart Power Extensions Units
The PowerBOX 3Px is a smart IoT power socket strip with 3 output sockets and IP/Ethernet connectivity. Each output socket on the power strips can be separately switched ON or OFF using the web interface and/or the NETIO Cloud service. The power strips can be used for applications including IT devices, lighting and audio-visual (AV) systems. The device offers intelligent integration through various protocols including JSON, Modbus/TCP, SNMP, MQTT-flex and Telnet.
PowerPDU Power Distribution Units
PowerPDU-4PS is a basic PDU with 4 IEC320 C13 outlets and individual socket control only. PowerPDU-4KS and PowerPDU-4C are metered PDUs with 4 IEC320 C13 outlets. Each of the outlets can be independently controlled (ON/OFF/RESET/TOGGLE) and provide power and energy measurements including Amps, Watts, kWh, Power Factor, Voltage and Frequency. PowerPDU-4C PDUs can be connected in series to provide multiple sockets outlets.
PowerCable Smart Socket Extension Cables
PowerCable is a single socket smart power strip and is available with one of four interfaces (REST, MODBUS, IQRF or MQTT) and either BS1363 UK, IEC320 or Schuko sockets and plugs. As standard the product is shipped in the UK with UK BS-1363 square pin plugs and sockets to offer an easy ‘plug and play’ installation.
PowerCable models and interfaces include:
- PowerCable-REST 101x has an open API can be integrated with third-party systems using one of three http-based REST protocols: XML, JSON or URL API. This is the base model available above from which the following variants can also be ordered online.
- PowerCable-Modbus 101x is a smart WiFi power socket which can turned ON/OFF via a web interface. Electrical measurements include: Amps, Watts, kWh, Power Factor, Voltage and Frequency and units can be connected in series.
- PowerCable-IQRF 101x is a smart power extension cable that communicates over the IQRF LPWAN network (868 MHz).
- PowerCable-MQTT 101x is a professional WiFi power socket featuring open API for integration with Cloud Internet of Things (IoT) services.
The ‘x’ in the model name ‘101x’ denotes the style of plug with G for UK, S for IEC and E, F and J for different styles of Schuko.
