note:
1. It is best to connect to the "DC output" because the rectification part of this type of electrical appliance is a common rectifier tube. When connected to the "high-frequency AC output", the rectifier diode of the conductor will be rapidly heated and damaged, and the diode will break down. Eventually the board burned out.
2. This board is high-frequency square wave AC and DC output, so the general inductive electrical can not bring the "motor electric fan coil transformer (such as amplifier audio), simple resistance and pressure drop-type small appliances, cheap resistance to resist buck LED lamps (eg LED night light, straw hat LED light fixture) thermostat type soldering iron, etc.
3. When connecting to a small load (LED lights, mobile phone charger, DVD set-top box, etc.), it is recommended to connect the output voltage to a low point such as: 200V.
4. It is recommended to increase the heat sink or fan to dissipate heat when working for a long time (≥100W).
5. The power supply can't be reversed. The other power supply and power line should have enough current. (There is a thick enough input power line to ensure the output. The converter is low voltage and high current and converts into high voltage and small current. For example, output 100W, input 12V. When the current needs about 9A)
6. Do not overload the output and do not short circuit.
7. The output high-frequency no-load voltage universal meter measurement will show high (is not correct, not the actual voltage, because the multimeter design is designed for 50HZ or 60HZ low-frequency AC, not designed for high-frequency AC, will test results The error is huge, even customers have tested 800V)
8, DC output voltage test problem, because the DC output of this board is not connected to the filter capacitor, plus this type of converter will have a certain spike when changing, the high voltage measurement will occur when the load is high, it is normal.
9, because it is bare board, output high voltage, pay attention to safety when using, can not be placed on the conductive table, such as metal tabletop, away from the battery pile head, to avoid accidental impact, should be connected to the input and output lines, after the switch, check the correct Re-energize.
Switch: The red line on the board is a switch to control the presence or absence of high voltage output.
Input voltage: 12V
It is recommended to use lead-acid batteries (lithium battery power supply and switching power supply, DC power supply type power supply, this type of power supply will cause the tube to overheat and burn out when power supply is insufficient) (8-14V), the output is not regulated, the input must ensure sufficient power (current ), otherwise it is easy to burn out the pipe
