CLIFF will also be using Productronica to launch a new range of locking 2.1mm and 2.5mm DC plugs and sockets which have been introduced in response to increased market demand for secure power connections.
Delta Electronics unveil 3-Phase 960W DIN rail power supply
Delta Electronics has enhanced its popular CliQ II DIN Rail Power Supply series with the addition of a new 3-Phase 960W power supply. The model DRP024V960W3BX provides 24V output with a full corrosion resistant aluminium body that can withstand up to 30G Shock test according to IEC 60068-2-27 and operates over a wide temperature range from -25°C to +65°C.
Tackling EMC in medical power supplies requires innovative design
All modern power supplies are of the switched-mode type, as these are smaller and more efficient than the old linear types. Switched-mode supplies, however, generate electromagnetic interference, both conducted and radiated, and require the incorporation of EMI filters.
Making sense of heat recovery
Mechanical ventilation and heat recovery systems are becoming increasingly necessary as we near the Zero Carbon goals for dwellings by 2016. In this ES Design magazine article, Mike Farrer, Technical Director of Stadium Power, highlights the need for the highest possible efficiency power sources to perform over a wide operating window.
Was Edison Right?
A new movement in the US is seeking to bring back DC power distribution at the building level, which can help reduce power losses. Sally Ward-Foxton discovers more in this interesting article from ES Design magazine.
