output overvoltage protection (45.5Vdc typ. / 48Vdc max.)
active (input inrush current limiter)
Overload / short-circuit current -- min. 40A (max. 47A) load impedance <40mΩ
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. 50V -- 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 QS40.361 DIN-rail power supply are the extremely high efficiency and the small size which are achieved by a synchronous rectification a bridgeless PFC circuit and additional unique design details. Large power reserves of 150% and built-in large sized output capacitors support the starting of heavy loads such as DC motors or capacitive loads. In many cases this allows the use of a unit from a lower wattage class which saves space and money. High immunity to transients and power surges as well as low electromagnetic emissions makes usage in nearly every environment possible. The integrated input fuse as well as the near zero input inrush current make installation and usage simple. Diagnostics are easy due to the DC-OK relay a green DCOK LED and the red overload LED. A large international approval package for a variety of applications makes this unit suitable for nearly every application.
