We analyze the non-isentropic Euler-Maxwell system under small relaxation times for magnetized plasmas and semiconductors. For near-equilibrium smooth periodic initial data, we establish uniform global existence of solutions relative to the relaxation parameter. Crucially, under slow time scaling, these solutions converge globally to the full energy-transport equations as the relaxation time vanishes. Our central innovation provides sharp error estimates between solutions of the non-isentropic system and its energy-transport limit, achieved through novel stream function techniques and enhanced energy methods. This work rigorously bridges these multiscale models while preserving their essential thermo-electromagnetic coupling.
