GE 66951 LET 75W-24-R – 75W 120V to 24V Electronic Step-Down Transformer

The GE 66951 (LET 75W-24-R) is a professional-grade 75W electronic transformer designed to step down 120V line voltage to a safe 24V AC output. Featuring a potted aluminum case for superior thermal management and a dedicated grounding wire, this transformer is 100% dimmable and engineered for maximum reliability in 24V low-voltage lighting systems.

Smarter Technology for Longer Life

GE Lightech transformers are built with field-effect transistors, allowing for a more compact footprint and higher efficiency than traditional bipolar models. The LET 75W-24-R features Auto-Thermal Regulation, which protects your system by proportionally dimming output voltage if internal temperatures exceed 90°C. Coupled with a self-preserving 125°C thermal cut-off, this transformer is designed to run cool and quiet in even the most demanding residential or commercial installations.

Key Features

• Quiet Operation: Triac dimmer compatibility ensures zero acoustic noise.
• High-Efficiency Design: Achieves up to 95% efficiency at full load for reduced energy waste.
• Compact & Durable: Rugged aluminum casing (1.25" W x 2.5" L) for easy integration into tight fixtures.
• Standard Compliance: UL Listed (E164062) for peace of mind and safety.
