PULS
Pulse Dimension Q is a series power supply with very high performance. The efficiency is high over a wide load range, which results in reduced power consumption and longer life regardless of load current. An average efficiency is 93.8% with a peak value of 94.6%. The power loss at idle is only 12 W.
The bonus power provides 50% extra reserve with retained 24 V dc (60 A) which is an advantage when connected loads have high starting currents and to bridge temporary current peaks. The bonus power is limited to 4 seconds to avoid constant overloading of the power supply and wiring. In addition to the bonus effect leave the unit a very high short-circuit current (for a number of milliseconds) that helps to secondary fuses. If the overload remains after 4 sec. Ports end in the so called, hiccup mode. When the output voltage drops below 21 V dc shut the unit by the end of the 18's. And then make a new start attempt. If the overload / short connection is gone restarts the power supply automatically. If the overload / short circuit persists, the unit output current of approx. 2 sec and then again turn off.
Heavy transient ensure operation also in very störrik electrical environment and also has QS40.244 active inrush current protection, which means a very low starting current, even if the unit has been in operation for a longer time. Especially useful for redundant / parallel-connected systems.
Simple diagnostics via DC-OK relay that falls on the output voltage deviates more than 10% from the set value, a green LED indicates DC-OK, the red LED indicates overload.
The unit can also be remote controlled for on / off function, three different connection options available. Can be used instead of expensive DC contactors when you need to break up the 24 VDC side. Note. remote control function has no safety circuit and therefore should not be used in the security context.
Active PFC reduces power consumption and harmonics close to zero. Moreover, the current distribution in the phases were much more even at the voltage asymmetry.

The power supply 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, for example. engines. How often you can use the bonus effect depends on the application. With the below chart and formula estimated the repeat time available for each individual application. The bonus power is available as soon as the power supply is started and after a short circuit
Bonus power | Work cycle | |
Po | Nominal load current | |
Ppeak | Peak current | |
To | Time between bonus effect | |
Tpeak | Peak current time | |
Work cycle | Tpeak/(Tpeak+To) | |
To= | Tpeak-(duty cycle)*Tpeak)/work cycle | |
Ex. Peak current (Ppeak) 50 A = 125%. Peak time is 3 seconds. Nominal load current (Po) is 30 A. 30 A = 75% of In. According to the diagram, the working cycle about 0.45. To = 3 - (0.45 * 3) / 0.45 = 3.6. Maximum repeat time of bonus power is 3.6 seconds. |
