SITOP modular
3-phase, 48 V DC
■
Overview
The 3-phase SITOP modular are technology power supplies for
sophisticated solutions and offer maximum functionality for use
in complex plants and machines. The wide-range input allows a
connection to almost any electrical power system worldwide and
ensures a high degree of safety even if there are large voltage
fluctuations. The power boost provides up to three times the
rated current for brief periods. In case of overload, you can
choose between constant current with automatic restart or
latching shutdown. The high degree of efficiency keeps energy
consumption and heating in the control cabinet low, and the
compact metal housing also saves space.
