ENERAL
ESCRIPTION
These PIANO series units are extraordinarily compact,
industrial grade power supplies that focus on the
essential
features
needed
applications.
The
excellent
presents many new and exciting opportunities without
compromising quality or reliability.
The mechanically robust housing is made of a high-
grade, 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.

B FEEDING OADS Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force). This power supply is resistant and does not show malfunctioning when a load feeds back voltage to the power supply.
