The short- term duration is hardware controlled by an output power manager. This BonusPower® is repeatedly available. Detailed information can be found in chapter 24.1. If the power supply is loaded longer with the BonusPower® than shown in the Bonus-time diagram (see Fig. 6-2), the max. output power is automatically reduced to 240W. **) Discharge current of output capacitors is not included. ***) This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. It is not guaranteed value which can be achieved. The typical value is about 56.8V. Peak current capability (up to several milliseconds) The power supply can deliver a peak current which is higher than the specified short term current. This helps to start current demanding loads or to safely operate subsequent circuit breakers. The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will be discharged and causes a voltage dip on the output. Detailed curves can be found in chapter 24.2. Peak current voltage dips typ. from 48V to 42V at 10A for 50ms, resistive load typ. from 48V to 42V at 20A for 2ms, resistive load typ. from 48V to 36V at 20A for 5ms, resistive load Nov. 2011 / Rev. 2.1 DS-QS10.481-EN All parameters are specified at 48V, 5A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0 Germany 7/27 |
