PULS
Puls Dimension Q is a new generation of power supply unit with very small construction dimensions and many technical benefits. The 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. 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% boost with retained 24 V, which is an advantage when connected loads have high starting currents. The unit also 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 unit and wiring. High efficiency provides long lifetime and low temperatures. The power supply unit can be connected for 2-phase operation with Inom up to 40°C. For higher temperatures, the load current must be reduced.
We recommend free space of 60 mm above/under the unit and 15 mm at the sides.
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.
Bonus power | Operating characteristics |
|
|
Po | Nominal load current |
Ppeak | Peak current |
To | Time between bonus power |
Tpeak | Peak current I time |
Operating cycle | Tpeak / (Tpeak + To) |
To | Tpeak - (operating cycle * Tpeak) / operating cycle |
Example: Nominal load current (Po) is 15 A. Peak current (Ppeak) is 24 A = 120%. The peak time is 3 seconds. 15 A = 75% of Inom. According to the diagram, the operating cycle is 50%. To = 3 - (0.5 * 3) / 0.5 = 3 Maximum repeat time of bonus power is 3 seconds. |
