The TRF MT1818-1.11 Standard Transformer is a robust mains power transformer designed to provide dual 18VAC secondary outputs for linear power supplies, audio amplifiers, industrial control systems, instrumentation, automation equipment, and other electronic applications. With a 40VA power rating and dual 18V secondary windings rated at 1.11A each, it delivers reliable, isolated AC power for medium-power electronic circuits.
The dual isolated secondary windings make this transformer ideal for creating split-rail ( 18V) power supplies, making it well suited for audio amplifiers, operational amplifier circuits, industrial controllers, measurement equipment, and other applications requiring symmetrical voltage rails. The secondary windings can also be connected in series or parallel where appropriate to accommodate different voltage and current requirements.
Built for dependable long-term operation, the MT1818-1.11 offers excellent electrical isolation between the primary and secondary windings, helping protect connected equipment while providing stable voltage output. Its durable construction ensures reliable performance in commercial, industrial, OEM, and educational environments.
The TRF MT1818-1.11 is an excellent choice for engineers, technicians, equipment manufacturers, and electronics enthusiasts requiring a high-quality transformer for demanding power supply applications.
