Description

Feature:

Power: 150W

Input voltage: DC12V

Output voltage: AC 0-110V-172V-200V-220V

Quiescent current: about 0.05A

Output waveform: high frequency square wave

Output frequency: about 20KHZ

Protection: None

Note:

1. This board is a high frequency square wave AC output, so general inductive appliances cannot be used! ! "Such as: motor, electric fan, coil transformer, etc. can not be used"

Another: simple RC and buck small electrical appliances, cheap RC and buck LED lamps may not be used;

2. When the electronic product is connected to the load (LED light, mobile phone charger, DVD set-top box, WIFA, etc.), a fast recovery diode or a low voltage gear such as 110V 172V should be connected in series at the output end;

3. It is recommended to increase the heat sink or external fan to work for a long time when the load is large. !

4. The positive and negative poles of the input power supply cannot be reversed. In addition, the power supply and the power cord must have sufficient current;

5. Because there is no protection output, do not overload or short circuit.

6. Because the output is a high-frequency square wave AC voltage, many general multimeters will not be able to measure or the measured display value is low or high (it is incorrect, not the actual voltage. You can use it with confidence);

Special reminder: the load is an electronic product. It is recommended to output a series of high-frequency diodes on our board and rectify it into a DC output. Because the rectification part of many electronic products such as switching power supplies is a common rectifier used to save costs. The "high frequency AC output" will lead to rapid heating of the rectifier diode in the electrical appliance, damage and breakdown, and short circuit. Eventually, the inverter board will burn out.

The output wiring voltage is as follows:

V0-V2 = 110V

V0-V3 = 175V

V0-V4 = 200V

V0-V5 = 220V

V5-V4 = 20V

V5-V3 = 45V

V5-V2 = 110V

V4-V3 = 28V

V4-V2 = 90V

V3-V2 = 62V
