1.Description:
   It is a 150W Inverter 50Hz/60Hz DC12V to AC 110V 220V Adjustable Power Supply Module Voltage Converter.

2.Feature:
  1>.Welding free, input terminal using 7.62 terminal, high frequency AC output using blue 301 terminal, DC output 7.62 terminal (directly loosen the terminal top screw, insert the wire, screw)
  2>.The voltage can be selected arbitrarily, through the jumper cap, no welding is requiredLarge output power
  3>.If the fan dissipates heat, the board can output 200W. The board uses a double-sided circuit board.

3.Parameter:
  1>.Input Voltage: DC12V
  2>. Output Voltage: 110V/200V/220V/280V
  3>.Output Wave Form: High frequency square wave or DC(un-filtered)
  4>.Output Power: 150W (When higher than 100W, please use cooling fan)
  5>.Current with 12V interface (No-load): 250mA
  6>.Working Frequency: 27kHz
  7>.Onboard Chip: ST SG3525A
  8>.FET:YPI7575C
  9>.Protection: No protection
  10>.Work Temperature: -25℃~85℃
  11>.Work Humidity: 5%~95%RH
  12>.Size:66*61*30mm

4.Cautions:
  1>.We recommend connect to "DC Output", because normal electric units are using normal rectifier. If connected to the "High Frequency AC Output", rectifier will heat up fast and damaged, diode will be destroyed;
  2>.This board has high frequency square wave AC output and DC output, so it can not drive inductive electric devices (such as motor, fan, resistor capacitor volt step-down units, small LED lights, etc);
  3>.When connected to small loads (phone chargers, DVD, etc), we recommend conect to lower voltage output, like 200V;
  4>.When working at high load (higher than 100W) or for long time, please use larger heatsink and fan for cooling;
  5>.Please do not mistake polarity. Need sufficiently big current for power supply and power cable;
  6>.No overload, No shorted at the output;
  7>.When output is high frequency and there is no load, the testing result with a multi-meter will be higher than actual.
