Simply good DIN-rail power supplies

Cost oriented

High reliability. Very attractive price.

With the new PIANO series, PULS-quality DIN-rail power supplies are now available for even the most cost oriented user. Through a fresh and innovative approach, the intrinsic properties of a PULS power supply (high reliability and long service lifetime) have now been introduced into a product that also has significant price advantages. PIANO prices are 20 to 40% below previous model prices.

Despite our low cost requirements, an MTBF of more than 1.4 million hours and efficiencies of 90.5 to 95.2% have been achieved. This innovation was made possible by a clever single-board design, cost-saving polycarbonate housing and a design team that was focused on an intelligent design for manufacturability.

PIANO details

Technical features

To ensure that your application continues to function properly, PIANO includes a DC-OK signal, an operational temperature range of up to +55°C (without derating) and large input and output terminals all within a light and compact housing. The 24V/10A unit, with a width of only 49mm, is the same size as the smallest “new to market” high-end products from other vendors.
