This power electronic transformer converts 220V to 12V and improves power quality. It delivers full power with a large allowance, ensuring stable output voltage and silent operation. The unit 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 more stable and flexible power transmission. Condition: Weight: 35-83g / 1.2-2.9oz Power: 20-50W, 60W, 120W, 160W (Optional) Adaptation range: Suitable for halogen lamps, supports up to 6 x 20W lamp beads. For more than 6 lamp beads, a higher wattage transformer is required. Selection method for electronic transformer: 1. Choose a transformer with the same power rating as the original lamp. 2. Select based on the total power of all lamp heads combined. For example, if the fixture has 5 x 20W or 10 x 10W lamp beads, the total power is 100W; a 105W transformer is recommended. Using an 80W transformer may cause failure. The selected transformer should have a power rating 5-20W higher than the total lamp bead wattage to extend service life and maintain brightness. Avoid selecting a transformer with excessively higher wattage, as this may slightly reduce brightness. Wiring information: Input (red wire) IN: 220-240V; Output (gray and white wires) OUT: 12V.
