Puls UK, a manufacturer of DIN rail power supplies, has won Atex approval for a selection of its single-phase Q-series units, allowing them to be used in potentially explosive environments. The units have been tested to EN 60079 - 15 and are approved for use in Zone 2 hazardous systems category 3G. Puls said no electrical changes were necessary to achieve the approval and that the standard had been met by dual conformal coating the internal components of the units. Atex is the framework for controlling explosive atmospheres and the standards of equipment and protective systems used in them. By achieving EN 60079 - 15 approval, Puls UK is now well placed to become a major supplier of power supplies to this specialised sector of the market. First shipments of the Q-series units are expected in the UK in May 2010.

Borri has launched the B50 single-phase uninterruptible power supply (UPS), a cost-effective solution for office and domestic use. The single-phase UPS has been designed to meet smaller back-up needs for applications such as small closed-circuit television systems and electronic point-of-sale and information-technology (IT) applications. The B50 ranges from 600VA to 1.5kVA, with four UPSs in the series. Most desktop computers operate within this power range, making the B50 suitable for preventing a PC from suffering power failures. The B50 is designed with Line Interactive Automatic Voltage Regulation (AVR) technology, which is said to be important to any small UPS. The AVR technology allows the input voltage to fluctuate by as much as -30 per cent to +20 per cent without having to engage the batteries, thus extending battery life. The AVR, combined with spike arrestors, protects a PC against sags and surges, providing a clean and constant supply to the user's IT equipment. The B5...
