DIN-Rail family

By taking a fresh approach, the high reliability and long service lifetime properties of PULS power supplies have now been implanted into a product range that provides significant price advantages. PULS says PIANO prices are reduced by up to 40% below previous model prices.

John Tyrrell, MD of PULS UK, says: "Despite the low cost design goals, an MTBF of more than 1.4 million hours and efficiencies of 90.5% to 94.5% have been achieved with a minimum service lifetime of typically 40,000h. These innovations have been made possible by a smart single-board design with cost-saving polycarbonate housing. The result is a compact, highly reliable and competitive supply; the 240W version requires a width of just 49mm on the DIN-Rail.”

These new supplies are purely convection-cooled and can operate from -10°C (some units from -25°C) 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 making installation simple and fast. Furthermore, the PIANO series  features  a  ‘DC-OK’  signal  that  can  be  used  to  monitor  the unit’s output voltage. 

Additional cost saving is made possible for applications where global use is not needed and a nominal input voltage of 200-240V is sufficient. By eliminating the cost penalty associated with a universal input range, products optimised for the higher input range provide a 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.
