Product Description
These PIANO series units are extraordinarily compact, industrial grade power supplies that focus on the essential features required in today’s industrial applications. The excellent cost/performance ratio presents many new and exciting opportunities without compromising quality or reliability. The mechanically robust housing is made of a high-grade, reinforced moulded material, which permits the units to be used in surrounding temperatures up to +70°C. Since typical industrial applications do not require multiple mains inputs, the reduction to a regional input voltage range (AC 200 240V) simplifies the circuitry and has significant advantages for reliability, efficiency and cost. The integrated DC-OK signal makes the unit suitable for many industry applications, such as process, automation and many other critical applications where preventive function monitoring can help to avoid long downtimes.
