Low Frequency 50HZ Inverter Drive Core Transformer Board Inverter Accessories Stablized Power Supply

New Low Frequency 50HZ Inverter Drive Core Transformer Board Inverter Acceories Stablized Power Supply

Dimensions: 65*80*35mm

Input voltage: DC12V (8-15V)

This board has no voltage regulation function

Output voltage: The wiring method of the 220-to-12V+12V transformer connected with the center tap is shown in the figure. The 12V terminal is connected to the output of the board. The 220V line input by the transformer has 220V voltage.

Use power: within 300

The frequency of this board will fluctuate due to the input voltage fluctuation (50HZ)

Start voltage: 8V

Undervoltage protection: 7V (need to choose, if undervoltage protection is required, the frequency will fluctuate with the voltage)

The default delivery is frequency stability, no undervoltage protection

Polarity protection: This board has the function of input positive and negative polarity reverse protection

Solder-free terminal: Input and output use solder-free terminal wiring, no need to solder, use screwdriver for wiring

Precautions:

1. The 12V end of the transformer must be a double 12V structure of 12V+12V (the 12V end is a three-wire structure)

2. Single 12V (only two lines at the 12V end) cannot be used.

3. The wiring must be connected to all the wires of the transformer before powering on and testing the machine. Do not power on while connecting.

4. The output of this inverter board is a square wave, which is not suitable for fan motor loads, because the fan motor with a square wave wilenerate heat and buzz. Low speed, etc. Series motors such as hand drills can be used.

5. If you want to output enough power, you need to ensure the input power, small battery, thin input line, small transformer, it is impoible to output high power.

6. Leakage inductance transformers cannot be used for this board, such as microwave oven transformers, paging stations, and transformers on launch pads. Several silicon steel sheets are inserted between the two primary and secondary stages of such transformers, and there is no-load current and power consumption. very high.

7. This board does not support the removed transformer on the UPS

8. The transformers wound by yourself are not suitable for this board. Most of the transformers wound by our friends do not meet the standard due to the small number of turns. As a result, ar connecting the driver board, the no-load current is huge and the driver board is burned out.

8. It is strictly forbidden to connect the high frequency transformer to this board, otherwise the driver board will be damaged
