The pseudospin-electron model with tunneling splitting of levels is considered. Generalization of dynamical mean-field method for systems with correlated hopping was applied to the investigation of the model. Within the alloy-analogy approximation the numerical investigations were conducted and electron spectrum was calculated. The dependences of the electron concentrations and average pseudospin values on chemical potential, asymmetry field and tunneling were obtained. It was shown, that in alloy-analogy approximation the model possess the first order phase transition to ferromagnetic state with the change of chemical potential and second order phase transition with the change of temperature.
