PULS
Puls Dimension Q is a new generation of power supply unit with very small construction dimensions and many technical benefits. The power supply unit has low inrush current (even with warm starts), active PFC, which provides a power factor close to one, expanded temperature range and active protection against line transients. (Not QS20) The power supply unit has high efficiency, which provides long lifetime both for the unit and adjacent products. Temperature increases in the cabinet are also kept at a low level. Furthermore, there is a relay output (DC OK) that is deactivated when the output voltage deviates more than 10 % from the set value. The bonus power provides an extra 50 % reserve with retained 24 V, which is an advantage when connected loads have high starting currents. The power supply unit has a high short-circuit current that simplifies tripping of secondary fuses. Both the bonus power and short-circuit current are time-limited to 4 seconds to avoid constant overloading of the power supply unit and wiring. QS20.241 If a short circuit lasts longer than 4 seconds, the power supply unit will continue in so-called hick-up mode. The output power is reduced to nearly zero for about 17 seconds. The power supply unit then makes a new start-up attempt for 2-4 seconds. If the short circuit remains, a new pause of 17 seconds is taken. Once the short circuit is remedied, the power supply unit automatically returns to service.For more technical information, consult the general information at the beginning of the power supply section.

Bonus power
The power supply unit has bonus power that enables high power extraction with retained 24 V DC for 4 seconds, which is a major advantage when connected loads have high starting currents, such as the case with motors. How often bonus power can be utilised depends on the application. With the following diagram and formula, the repeat time can be calculated for each application. The bonus power is available as soon as the power supply unit is started and directly after a short circuit.
