FM Focus Power Ethernet launches the PE Socket
British start-up Power Ethernet has introduced an innovative and technologically advanced solution that creates a reliable wired computer network without the usual complexity and associated time and cost of running Ethernet cable.
Called the PE Socket, the device uses Power Line Communications (PLC) to transmit IP network information, used by computers, CCTV cameras, air conditioning systems and digital signage, over your building’s original power wires. Expanding a building’s
computer network to meet modern connectivity demands is often no mean feat, requiring expensive Ethernet cable runs or a reliance on wireless networking, which can rarely offer a robust connection for multiple users.
The PE Socket is designed to address these issues, offering a reliable connection that is not affected by signal-degrading walls – and because it replaces a British double- gang power socket, fitting into a standard 35mm deep back box, the need to damage or modify a building’s walls or floors in order to run new cable is negated. This saves man hours, material and redecoration costs.
By integrating a four-port managed PLC Ethernet switch into a highly aesthetically pleasing flush-mountable socket, Power Ethernet implements
a robust computer network into the electrical fabric of a building. Installation is as simple as replacing a current power socket, and can be undertaken by any electrician without specialist networking knowledge.
Previously a concern for PLC, the PE Socket’s advanced filtering components minimise the effect of any electrical noise on the circuit and therefore delivery the maximum available bandwidth, while the design incorporates over 100 additional electronic components over a typical PLC adapter in order to improve the network quality as well as the durability of the unit.
PE Sockets are available from a number of leading electrical wholesalers. For further information including stockists, call 0845 0044445 or visit

New Range of air compressors launched by FPS A new range of variable-speed air compressors from FPS Compressors is claimed to represent a significant step in maximising energy efficiency. Called the Galileo range and manufactured by Power System Group, the new machines differ from standard variable speed compressors by using direct drive, permanent magnet motors and sophisticated controls to bring significant gains in energy efficiency.
Normal variable speed compressors are fitted with an asynchronous or induction type electric motor that is usually paired with a frequency controller or inverter. This arrangement can be very useful in saving power when compared to the on/off regulated compressors which are still in frequent use. This well-known arrangement however, whilst being a step forward from older technology, is less energy efficient during periods of low demand and very high demand. During low demand the speed of the motor is reduced and at low
speed the induction motor becomes less efficient. When demand is at its highest the energy losses in the inverter also penalise efficiency.
The new Galileo compressors are based on the proven PS-DV Series platform of variable-speed compressor with highly efficient compressor air end, direct drive and sophisticated controls. The adoption of a new generation permanent magnet motor however brings further gains in energy efficiency to what are already very efficient machines.

The specially designed synchronous motor, using permanent magnets, provides several benefits over asynchronous motors. These include the avoidance of extra field current normally required to generate the magnetic field in the rotor, very high flux density, high and constant torque, higher power factor and efficiency across a very wide range of operating speeds. These factors make Galileo models highly efficient, delivering further savings of around 9-12% when compared to other variable speed compressors.
There are over 25 models in the Galileo range, offering a wide range of performance, from 9 kW to 180 kW with operating pressures between 7.5 bar and 13 bar and with capacity from 1570 L/min to 30,000 L/min.
