12V Switching Power Supply

AC input range by switch Protections: Short circuit / overload / overvoltage built-in fan forced air cooling with a cooling fan switch control LED power indicator is 100% full load burn high efficiency and low cost and high reliability guarantee high quality of life of a two-year maintenance free life input parameters Input voltage range: 110ac ~ 220Vac Frequency range: 47Hz ~ 63Hz efficiency (typical): 83.5% for earth leakage current: input to ground ≤0.5mA / input to output ≤0.25mA Second, the output specifications of the DC output voltage: 12V Output rated current: 29.17A Note 1 Rated output power: 350W Output ripple and noise 0 ~ 65 ℃: 180mVp-p output voltage adjustment range Note 2: Rated output voltage ± 10% output voltage accuracy: 1% output voltage Regulation: ± 0.5% output load regulation: ± 1% III Overload protection: in the range of 105 to 150% of rated load power protection, reached the point when the current voltage must be instantaneous shutdown or hiccup state, troubleshooting automatically return to normal voltage protection: 110 to 150 percent within the range of the output voltage of power protection, the internal power supply will limit the maximum output voltage circuit protection: When the output ends connected directly to the power supply should be stopped (after troubleshooting automatic recovery) . Without prejudice to electrical equipment IV Environmental Operating ambient temperature range: -20 ℃ ~ + 60 ℃ Operating humidity range: 20% ~ 90% RH Storage temperature range: -40 ℃ ~ + 85 ℃ Storage humidity range: 10% ~ 95% RH Five other type size: 199 * 90 * 50 (L * W * H) Connection: 9 9500 Screw terminals Weight: 0.9Kg / Taiwan Packing: 20 / box, note 1. Unless otherwise specified, all parameters are at nominal input voltage, rated load, measured at 25 degrees. 2. Ripple noise is the use of 12 # twisted-pair connections, and at 20MHz of bandwidth, parallel 0.1uF and 10uF capacitor.
