output overvoltage protection (31Vdc typ. / 34Vdc max.)
NTC (input inrush current limiter)
Overload / short-circuit current -- 9.8A continuous current / 9.2A typ. intermitted current peak value for typ. 60ms. Load impedance 50mΩ. Discharge current of output capacitors is not included. / Max. 3.5A intermitted current average value (R.M.S.) Load impedance 50mΩ
Series / parallel operation -- Power supplies can be paralleled for redundancy to gain higher system availability. Redundant systems require a certain amount of extra power to support the load in case 1 power supply unit fails. The simplest way is to put 2 power supplies in parallel. This is called a 1+1 redundancy. In case 1 power supply unit fails the other 1 is automatically able to support the load current without any interruption
Back-feeding loads max. 35V -- The unit is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is ON or OFF. The absorbing energy can be calculated according to the built-in large sized output capacitor.

These PIANO series units are extraordinarily compact industrial grade power supplies that focus on the essential features needed in todays 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. The unit is equipped with an auto-select input voltage stage for 100-120V and 200-240V mains systems many safety approvals and a wide operational temperature range which makes the unit applicable for global use. The addition of a DC OK signal makes the unit suitable for many industry applications such as process control factory automation or many other critical applications where preventive function monitoring can help to avoid long downtimes.
