Dual Voltage Input with Flexible AdjustmentSupports AC 110V120V and 220V240V inputs. Lower power models (12V 1A5A, 12W60W) feature automatic voltage adjustment, while higher power units (12V 10A60A, 120W600W) include a side-mounted selector switch for easy manual voltage setting. High-Current Output with Wide CompatibilityDelivers stable DC 12V output with current options from 10A to 50A (120W600W), ideal for LED strips, car audio systems, CCTV cameras, and other 12V devices. Note: resistive loads like LEDs can use full power; motor-driven devices require consideration of higher startup current.
