Converting standard 220VAC or 110VAC line voltage down to a stable 18VAC (or 12VAC) secondary output at 600mA, it features high-permeability silicon steel EI laminations, pure copper windings, and vacuum-varnished insulation. Designed for continuous-duty operation, it provides robust dielectric isolation and over-voltage surge resistance to protect sensitive downstream high-voltage generator modules and microcontroller assemblies.\n    \u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 3: Performance \u0026 Verification (P\u0026V) Table --\u003e\n  \u003cdiv style=\"margin-bottom: 24px;\"\u003e\n    \u003ch3 style=\"font-size: 15px;
