We present flux-calibrated integrated spectra for 10 concentrated Galactic open clusters located in the fourth quadrant of the Milky Way. The spectra were obtained at CASLEO (San Juan, Argentina) in the visual range. For one of the clusters: BH 202, we present for the first time its fundamental parameters. For the remaining clusters we provide independent information of that derived from colour magnitude diagram studies. Using the equivalent widths of the Balmer lines and comparing the cluster spectra with solar-metallicity template spectra of Galactic star clusters with known properties, we derive both foreground E(B-V) colour excesses and ages for the whole sample.
