Includes five premium red wire connectors (high-quality nylon shell & metal spring) for enhanced safety, insulation, and secure wiring. The compact, enclosed design fits neatly into HVAC control boxes or industrial panels, making installation faster, safer, and more reliable
  • Wide Voltage Input Compatibility & Clear Wiring Identification - Supports 120V, 208V, and 240V multi-tap primary inputs (WHT–BLK–RED–ORG) with a 24V AC secondary output (RED–GRN), rated at 40VA. Each lead is clearly identified for fast, accurate wiring, ensuring compatibility with HVAC, furnace, and industrial control systems while maintaining consistent performance across varying voltage environments
  • Stable Output & Precision Performance - Delivers consistent, clean 24V power with a precise no-load voltage range of AC 26.6V–27.5V. Maintains reliable control circuit operation, preventing malfunctions in HVAC systems, relays, and gas valves that depend on steady low-voltage power
  • Industrial-Grade Durability & Materials - Constructed with high-purity copper windings and premium silicon steel core laminations for low energy loss and cool operation. The transformer is oil-impregnated and fully encapsulated to enhance insulation, heat dissipation, and long-term stability. Its rugged build ensures reliable performance and strong resistance to dust, moisture, and harsh industrial environments
  • Broad Compatibility & Trusted Replacement Options - Designed as a reliable replacement for multiple 24V 40VA control transformers used in HVAC and industrial systems. Compatible with Gemline GT446, Supco SXT105, UEI UET105 / UET115, Grainger 6WU91, Jard 4031F, Mars 50203, White-Rodgers GT4031F / 90-T40F3, Armstrong TWF424-40, Source 1 S1-T2404F, Packard PF42440, Robertshaw 620-206 / 620-406 / 620-482, and Honeywell AT140A1018 / AT40A1121 / AT40A1139 / AT40B1214
