RS Components LOGO!Power supplies

April 2018 Electrical Power & Protection

RS Components has announced availability of the fourth generation of LOGO!Power power supplies from Siemens. These new ultra-narrow units have the same design as the Siemens LOGO!8 logic controllers and deliver up to 100 W for distribution boards, as well as being fully compatible with the third-generation range of devices.

The portfolio now includes two additional devices as well as additional functionalities and scope for a range of applications including: industrial automation, such as simple packaging machines, garbage presses, conveyor belts and sorting systems; and in building automation, such as lighting controls, heating control system extensions, or door and gate controls. The series also offers an extended operating temperature range from –25 to 70°C, enabling their use in cold environments.

Offering housing widths of 18 to 72 mm, the compact fourth-generation devices offer a reduced width with respect to the previous generation, which allows more flexible mounting on DIN rails in distribution boards, or directly on walls or ceilings. They can also be mounted side by side with other devices, for example, supplying power to adjacent LOGO! intelligent logic modules.

Providing outstanding energy efficiency both in standby and running operation, the series offers efficiencies of up to 90 percent over the entire load range, and no-load losses of less than 0,3 W. The integrated current monitor also helps during commissioning and servicing: current output can be read out in real-time as a voltage value using a measuring point. The disconnection of cables for conventional current measurement is no longer required and the system continues to be supplied with direct voltage without interruption. The series also offers a diagnostic LED ‘DC OK’ signal to indicate status.
