A class of charged analogues of superdense star model due to M.C. Durgapal and R.S. Fuloria, is obtained by using a particular electric field, which involves a parameter K. The members of this class are seen to satisfy the various physical conditions e.g. c 2 ρ≥3 p≥0, dp/ dr<0, d ρ/ dr<0, along with the velocity of sound condition dp/ c 2 d ρ<1 and the adiabatic index (( p+ c 2 ρ)/ p)( dp/( c 2 d ρ))>1 for the interval 1< K≤1.73 with the maximum mass 3.2860 M Θ and the radius 18.3990 km. It is interesting to note that the velocity of sound and the ratio p/ c 2 ρ are monotonically decreasing towards the pressure free interface for 1< K≤1.10216 which presents a relevant modelling for massive star like Neutron star or pulsar. In the interval 1< K≤1.10216, the maximum mass and the corresponding radius are given as 1.9672 M Θ and 15.9755 km respectively.
