7 / 22 page CD5.241 CD-Series DC/DC Converter 24V, 5A 6. HOLD-UP TIME The input side of the DC/DC converter is equipped with a bulk capacitor which keeps the output voltage alive for a certain period of time when the input voltage dips or is removed. The bulk capacitor can be discharged by loading the DC/DC converter on the output side or through a load which is parallel to the input. There is no protection in the DC/DC converter which prevents current from flowing back to the input terminals. If prevention is needed, an external diode should be used. Hold-up Time typ. 11.8ms input 24Vdc, output: 24Vdc, 2.5A, see Fig. 6-1 typ. 6ms input 24Vdc, output: 24Vdc, 5A, see Fig. 6-1 Fig. 6-1 Hold-up time vs. input voltage 0 2 4 6 8 12ms 18 20 22 24 28Vdc Input Voltage Hold-up Time (a) 24V, 2.5A, typ.
