In this study we present flux-calibrated integrated spectra in the range 3800-6800 angstrom for 10 concentrated southern Galactic open clusters. Using the equivalent widths of the Balmer lines and comparing the cluster spectra with template spectra of Galactic star clusters with known parameters, we derive both foreground interstellar reddening values and age. For 5 open clusters these two parameters have been determined for the first time, while for the rest of the sample the results show good agreement with previous studies. The age and reddening distributions of the present sample of relatively faint open clusters match those of open clusters with known parameters in the same Galactic sectors.
