This 220V to 12V electronic transformer efficiently converts household voltage for low-voltage halogen lamps, featuring selectable power output from 20W to 160W. Optimized circuit design ensures stable voltage transmission with zero noise operation, compatible with dimming systems and remote controls. Compact lightweight construction (35-83g) enables easy installation in confined spaces. Features overload protection and 5-20W power buffer design to extend lifespan of connected lamps. Includes clear input/output wiring labels (red for 220-240V AC input, gray/white for 12V DC output). Specifications: Power Options: 20-50W/60W/120W/160W Maximum Load: Supports up to 6x20W halogen bulbs Safety Margin: Requires 5-20W higher rating than total lamp load Certification: CE/RoHS compliant
