PIC240.241C 24V, 10A, SINGLE PHASE INPUT POWER SUPPLY AC 200-240V Regional Input Cost Optimized without Compromising Quality or Reliability. Width only 49mm Efficiency up to 91.4% Full Power Between -10°C and +55°C DC-OK Relay Contact Included 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA These PIANO series units are extraordinarily compact, industrial grade power supplies that focus on the essential features needed in today’s industrial applications. The excellent cost/performance ratio presents many new and exciting opportunities without compromising quality or reliability. Output voltage Adjustment range Output current The mechanically robust housing is made of a highgrade, reinforced molded 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 addition of a 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.
