Cost-efficient DIN-Rail power supply family

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 by our specialist PULS design team focused on an intelligent design for cost-effective manufacturability. 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  series features a DC-OK signal that can be used to monitor the unit’s output voltage.
