Contactor series delivering reduced energy consumption

A new series of AC/DC coil compatible contactors is available from Schneider Electric, through RS Componenets. Schneider has upgraded its TeSys D range with the TeSys D Green range that features lower energy consumption and AC/DC coils, meaning every coil can be energised with either AC or DC current.

Making it easy for customers to upgrade and gain the improved energy efficiencies, the new range is backward compatible with all current TeSys D accessories and support products and offers consistent low-energy contactors that handle 9 to 80A, and cover control voltages from 24 to 500V AC or DC.

Designed to take up less space in machines and electrical cabinets, the range offers a number of advantages. For example, low control current leads to lower energy consumption with a reduced coil power of just 0.5W at 24V DC, making a major contribution to the energy efficiency of a machine. In addition, a special contactor product that handles 40 to 65A and can connect directly to PLC control, as the device can be driven by a common 24V DC / 500mA static output, means that a relay interface is no longer required.

Meeting the SEMI F47 standard, the range offers higher resistance to voltage surges and grid disruptions to provider higher uptime. The contactors also offer reduced contact bounce as the devices retain the same high resistance to shock and vibration as the TeSys D range.

Other advantages include a constant closing and opening time, regardless of voltage fluctuation, delivering reliable repetitive actuation. Also, when maintenance is required one TeSys D Green can replace many standard contactors.
