We have considered the model of the phase transition of the second order forthe Coulomb frustrated 2D charged system. The coupling of the order parameterwith the charge was considered as the local temperature. We have found that insuch system, an appearance of the phase-separated state is possible. Bynumerical simulation, we have obtained different types ("stripes", "rings","snakes") of phase-separated states and determined the parameter ranges forthese states. Thus the system undergoes a series of phase transitions when thetemperature decreases. First, the system moves from the homogeneous state witha zero order parameter to the phase-separated state with two phases in one ofwhich the order parameter is zero and, in the other, it is nonzero ($\tau>0$).Then a first-order transition occurs to another phase-separated state, in whichboth phases have different and nonzero values of the order parameter (for$\tau<0$). And only a further decrease of temperature leads to a transition toa homogeneous ordered state.
