output overvoltage protection (58.8Vdc typ. / 60Vdc max.)
Overload / short-circuit current -- 14.5A continuous current / 19A typ. intermitted current peak value for typ. 1s. Load impedance 50mΩ. Discharge current of output capacitors is not included. / Max. 7A intermitted current average value (R.M.S.) Load impedance 50mΩ
Series / parallel operation -- Buffer units can be added in parallel to increase the output ampacity or the hold-up time. 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. 63V -- 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 today 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 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.
