As soon as the input is turned off, the output capacitor will be discharged and the voltage will dissipate according to the curves in Fig. 8-2. The lighter the load, the longer the hold-up time. Half the load means twice the hold-up time. The hold-up time depends on the load characteristic. The curves below show the hold-up time for a load with a resistive and a constant power characteristic. The hold-up time is defined as the period of time when the input is turned off and until the output voltage falls below 72V –15% (61.2V). This value is defined in the IEC61131-2 as the lower limit for the supplying voltage. -15% Hold- up Time Zero Transition Output Voltage Intput Voltage Fig. 8-2 Hold-up time vs. input voltage 72V 36V 54V 42V VOUT 66V 48V 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.5 6.0 6.5 7.0 7.5 8.0 5.0 8.5 9.0 13.3A, constant power load, typ. 13.3A, resistive load, typ.
