ACME Electric TB181143 Transformer

ACME Electric TB181143 is a TB Series Open Core & Coil Industrial Control Transformer that converts 120/240 V AC mains to a 12/24 V DC secondary. This single‑phase, 100 VA transformer operates at 50/60 Hz and is designed for control circuits in industrial equipment, supplying a DC control voltage derived from a standard AC supply. The primary winding accepts 120/240 V AC, and the secondary delivers 12/24 V DC, enabling direct interfacing with DC relays, timers, and other low‑voltage control devices in automation and instrumentation applications. With its open‑core and coil design, the TB181143 is intended for mounting in electrical enclosures or on panels where windings and terminations are accessible for wiring and service. The 100 VA rating indicates its capacity to power modest control loads without excessive voltage drop when operated within the specified frequency range of 50–60 Hz. As a single‑phase transformer in AC mains environments, it remains a practical choice for applications that require a compact, DC‑output control supply sourced from a standard 120/240 V source.
