Protection functions
output overvoltage protection (32Vdc typ. / 37Vdc max.)
active (input inrush current limiter)
Overload / short-circuit current -- min. 30A (max. 40A) load impedance <50mΩ
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. 34V -- 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.

Benefits
AC 200-240V Input
Width only 70mm
Efficiency up to 94.5%
Very Low No-load Losses
150% (720W) Peak Load Capability
Safe HiccupPLUS overload mode
Easy fuse tripping due to high overload current
Full power between -25°C and +60°C
DC-OK relay contact
Quick-connect Spring-clamp Terminals
3 Year warranty
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 QS20.244 is a device for 200-240V non-public mains only. This supports regional applications and offers additional cost and space savings. If a wide-range unit with PFC is preferred choose the QS20.241. 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. Diagnostics are easy due to the dry DC-ok contact a green DC-ok LED and red overload LED. High immunity to transients and power surges as well as low electromagnetic emission makes usage in nearly every environment possible. 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.
