Vibration input voltage range: AC95V to 265V; rated input voltage: AC110V or AC240V 1.5 AMP is the input rated current. 150VA of input power, >88% efficiency (TYP) DC 12V/16V/18V/19V/20V/22V/24V (0.9/+0.8V at range load, 0/+.8V without load) is the output voltage. Current output: 12V–20V (4.5%), 22–24% (3.8%) Ovet voltage protection and overload protection. protection against short circuits. 1000mv ripple noise +/-5% for line regulation and +/-5% for load regulation
