active (input inrush current limiter)
Overload / short-circuit current -- min. 3.5A (max. 4.2A) load impedance <25mΩ
Series / parallel operation -- Power supplies can be paralleled to increase the output power. The output voltage of all power supplies shall be adjusted to the same value (+/-100mV) in Single use mode with the same load conditions on all units
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.

The most outstanding features of this Dimension Q Series DIN-rail power supply are the high efficiency and the small size which are achieved by a synchronous rectification and further novel design details. The QSeries is part of the Dimension family existing alongside the lower featured C-Series. With short-term peak power capability of 150% and built-in large sized output capacitors these features help start motors charge capacitors and absorb reverse energy and often allow a unit of a lower wattage class to be used. High immunity to transients and power surges as well as low electromagnetic emission makes usage in nearly every environment possible. The integrated output power manager a wide range input voltage design and virtually no input inrush current make installation and usage simple. Diagnostics are easy due to a green DC-ok LED and red overload LED. Unique quick-connect spring-clamp terminals allow a safe and fast installation and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.
