12v电变压器

Main Technical dataOutput voltageAC220V±10%Output frequency50/60Hzoutput voltage wave formmodified sine waveOver voltage protectionDC14.5-15.5VLow input voltage warningDC10.4-11.0VLow voltage protectionDC9.7-10.3VContinues AC output power1200WMaximum AC output power1250WDimensions223*95*53mmWeight748gFuse70A1. Input voltage range: The amount of the value of DC input voltage 24V, allowing range :15-32V The amount of the value of DC input voltage 12V, allowing range :7-14V 2. Peak efficiency:when the input voltage and load rating, the machine efficiency ≥ 95% 3. Battery drain with on AC load(at 12V input):<3.6W 4. Protection Features A. Overheat protection: inverter internal temperature rose to 75 °C, the red light. When the temperature drops, the inverter stops meditation alarm. When the internal temperature reached 85 °C shut out in 3 seconds, red lights. When the temperature drops, the inverter automatically start in 0.1s B. Overload: When the input voltage rating, output current 31-35A when the yellow light within 10-20 seconds, turn off the output, the protection response time ≤ 0.1s. When the load returned to normal range, the inverter will automatically start in 0.1s C. Output short circuit protection: when input voltage rating, load short-circuit, the output off to protect the response time ≤ 10ms, yellow directions. When short-circuit rule, the inverter will automatically start in 0.1s D. Input voltage protection: when input voltage down to 10V output close and lock in the 10s, green micro-light, are not allowed to restart automatically. E. Input over-voltage protection: when input voltage is increased to 24V fixed output of 12V is automatically transferred to the working mode F. Input voltage polarity protection: Input power connection counter (-36V, 1 min), the inverter should be self-protection so as not to be damaged. 5..Electromagnetic Environmental Adaptability A. Shell protection grade: according to QC / T 413 in 1P43 (not powered) B. Electrostatic discharge immunity: 3 (according to 0.5Hz the discharge of the positive and negative 10 times) C. RFEMS: 3 6. Applications: Lighting,Laptop,Games,Portable TV,Hand-held video camera,Digital Cameras,Small music center,Printer,Portable DVD,Battery Charger,Phones ,Electric shaver,Portable CD / MD machines,PDA Pocket PC,Kara OK MP3/MP4/MP5 Etc.
