Features: 3.Input voltage: AC110V 50Hz/60Hz; Output voltage: AC12V; Power factor: 0.99; Rated power: 60W/80W/105w/160W (maximum power)4.Wiring method: red is AC110V input; white is AC12V output (the output is high-frequency voltage and cannot be measured with a multimeter).5.Using high-grade coils, it has the advantages of high power factor, low temperature rise, no noise, and no flicker.6.Commonly used in crystal lamps; low-voltage lamps; chandeliers; ceiling lamps; bean bladder lamps; grille spotlights; mirror headlights; aisle lights; wall lamps, etc.Note:1. The white wire is the output wire, do not connect it as the input wire.2. The load wattage shall not be higher than the transformer wattage (60W).3. The product can only be used with resistive loads (12V), such as halogen lamp beads or heating wires.4. The output of the transformer is high frequency 28 k Hz to 40 k Hz. The multimeter cannot measure the voltage. You must use an equivalent 12V halogen lamp to test. As long as the lamp bead lights up, it is good.Specifications:Material: PlasticColor: BlackBrand name: BQLZRSize:60W Transformer: 60x30x25mm/2.36inchx1.18inchx0.98inch (LxWxH)80W Transformer: 81x37x24mm/3.18inchx1.45inchx0.94inch (LxWxH)160W Transformer: 105x48x27mm/4.13inchx1.88inchx1.06inch (LxWxH)105w Transformer: 81x38x27mm/3.18inchx1.49inchx1.06inch (LxWxH)Weight: 355 gPackage include:1 x Transformer 60W1 x Transformer 80W1 x Transformer 105w1 x Transformer 160W
