Power supplies Power supplies Sold by AA Electric 1-800-237-8274 Lakeland, FL • Lawrenceville, GA • Greensboro, NC • East Rutherford, NJ www.A-Aelectric.com Transformers and power supplies are important links in the supply of power to automation systems. They are the core of each and every switch cabinet. A control voltage of 24 V has become generally established around the world as the power supply for all electric modules. But other voltages are still in use. The power supply must be chosen with extreme care, because it is crucial for the reliable functioning of all the components it supplies. Power supplies consist of a transformer that changes an a.c. voltage into an a.c. voltage of a different value. The secondary a.c. voltage is transformed into a pulsating d.c. voltage via a rectifier, and then smoothed by means of a filter circuit. In the case of stabilised power supplies, the output voltage is held constant by a stabilising unit. Weidmüller power supplies have proven themselves over many years in the supply of power to electronic modules. They are CE certified and comply with the requirements of DIN EN 50081-1 and DIN EN 50082-2 (EN 61000-6-2 with effect from 1 April 2002). This means that they can be used in adverse industrial environments, small-scale industrial installations and also in residential areas. Weidmüller offers power supply modules suitable for industrial use: • non-stabilised transformer mains adapters • primary switched-mode regulators • d.c. converters Input voltage to DIN IEC 38 The tolerance band of the standard mains voltage of 230 Vac/400 Vac is extended by ±10% as from 2003. Weidmüller power supplies already satisfy the regulations stipulated in DIN IEC 38. Worldwide use Weidmüller power supplies carry international approvals for worldwide use in many different applications. They are used in mechanical engineering, industrial automation, systems engineering, the power industry, production lines and building technology. Temperature range Power supplies continuously create power loss that is released as heat. This heat is dissipated via a cooling unit and the surface of the enclosure. Depending on type, Weidmüller power supplies can be used in ambient temperatures up to 60°C. Compact design Weidmüller power supplies can be used in restricted spaces due to their compact design and small footprint. This saves space in the switch cabinet and reduces costs.
