Reliable DIN-Rail Power Supplies for Mid-Market Applications

We now extend our product range to new market segments. Applying new concepts from design to manufacturing, the PIANO series offers reliability, service life-time and efficiency figures usually available only in more expensive products.

The Mean Time Between Failure (MTBF) figures of the PIANO-Series are as high as 1.5 million hours and the minimum service life-time is typically 40,000 hours. Efficiency figures vary, depending on the version, from 90.5% up to 94.5%. The 240W version consumes a width of only 49mm on the DIN-Rail, therefore it offers the same size benefit as the newest and most costly products from other vendors.

Robust even for demanding applications, these purely convection cooled units can operate from -10°C (some units even from -25°C) up to +70°C. Power derating is typically only required above +55°C. The PIANO series is easy to use because it clicks smoothly onto any standard DIN-Rail and includes large-sized terminals which makes wiring simple and effortless. Furthermore, the PIANO series also offers a DC-OK signal that can be used to monitor the unit’s output voltage.

Additional cost saving is possible in applications where global use is not needed and a nominal input voltage of 200-240V is sufficient. By eliminating the burden associated with a universal input range, products optimized for the high range provide a much better cost vs. performance position.

Currently available are 24V/5A and 24V/10A models for input voltages from 200-240V. Additional products suitable for all global input voltages from 100V-240V will be available in Q2/2015. The new PIANO series allows users to save on costs without compromising on the benefits of a reliable, efficient and easy-to-use power supply.
