Dantech Electronic Engineering, the UK manufacturer of specialist power supplies and ancillary equipment designed for security applications, has launched a new range of MultispanTM PoE + Ethernet Switch products.

Providing PoE+ 30W power and Ethernet transmission for up to four IP devices, the new Dantech ‘Multispan’ solutions consist of a dedicated Multispan PoE power device and a separate dedicated Cisco switch, within a single secure enclosure. An installer can choose to locate the Multispan device either at the network endpoint or midpoint.

Using the Cisco 10/100/1000 Gigabit full-duplex unmanaged switch, one network uplink and up to four IP devices (i.e. surveillance video, access control, or intercom) can be connected over Cat5 UTP cable. With no network configuration required, the connectivity saves installation time and money, according to the manufacturers.

In addition to the standard Multispan PoE + Ethernet Switch model, to guard against mains power outages, the device is also available with integrated battery backup. The MultispanUPS versions maintain both the PSU and Ethernet switch, and for a typical 5W load, the 10Ah battery model will supply continuous power for 100 hours. These models are suitable it’s claimed to prevent any power and IP transmission supply failures, and the associated time-consuming IP end-device re-boot issues.

Tim Scott, Director at Dantech Electronic Engineering, says: “Responding to demand from customers, Dantech has engineered a flexible solution to enable installers to provide combined PoE & Ethernet transmission for a range of IP applications, and locate it at an end or midpoint of their choice. Along with the delivery of ultra-robust and secure power, for complete peace of mind, we chose Cisco technology for the Ethernet switch component due to the company’s world-famous reputation for reliability, making them our ideal technology partner.”

The range of four-port combined PoE+ power and Ethernet switch products is available in indoor (including rackmount) and outdoor enclosures. Visit
