This power electronic transformer converts 220V to 12V and helps improve power quality. It delivers full power with a large allowance, providing stable output voltage and operates silently. The transformer is reliable and practical, compatible with dimming, segmentation, and remote control functions. Its compact size and lightweight design make it easy to install. An optimized circuit matching design ensures stable and efficient power transmission.Specifications: Condition: Weight: 35-83g / 1.2-2.9oz Power: 20-50W, 60W, 120W, 160W (Optional) Application: Suitable for halogen lamps; supports up to 6 pieces of 20W lamp beads. For more than 6 lamp beads, a higher wattage transformer is required.How to choose the right electronic transformer: 1. Match the transformer power to the original lamp's specifications. (e.g., if the original transformer is 160W, select a 160W model). 2. Calculate the total wattage based on the number and power of the lamp beads. (e.g., 5 x 20W or 10 x 10W lamp beads total 100W; select a transformer with 105W). Note: The transformer power should be 5-20W higher than the total lamp bead wattage to extend service life and maintain brightness. Avoid selecting a transformer with significantly higher power, as it may reduce brightness.Wiring Information: Input (red wire): 220-240V Output (gray and white wires): 12VPackage Includes: 1 x Electronic TransformerNote: The model of this product will be shipped at random.
