Protection functions
output overvoltage protection (30Vdc typ. / 32Vdc max.)
active (input inrush current limiter)
Overload / short-circuit current -- min. 60A (max. 70A) 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 the DIMENSION QSeries DIN-rail power supplies are the extremely high efficiencies and the small sizes which are achieved by a synchronous rectification and other technological designs. The QS40.244 is a device for 200-240V mains voltages. Large power reserves of 150% 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 emission makes usage in nearly every environment possible. The integrated output power manager and input fuses 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 DC-OK LED and the red overload LED. A large international approval package for a variety of applications makes this unit suitable for nearly every application.
