Low frequency iron core transformer inverter drive board. This board input DC, 24V, output AC24V or DC, 12V, output AC12V Input: DC 24V, maximum 30V / DC 12V, the maximum undervoltage protection value is about 8V, the maximum is 15V Output: AC Output waveform: square wave Output frequency: AC 50HZ Output power: 100W without fan There is a fan to diipate 200W, Output current: 10A, pay attention to the need for fan cooling Input reverse connection protection: not afraid of input reverse connection Dimensions: 9.6*3.9*1.8 cm Please string your own fuse for 12V input, 100W string 10A fuse, and 20A fuse if there is a fan to diipate 200W Choose a suitable transformer according to your own needs. Generally, you can choose a power greater than 15W for 10W. It is more suitable to choose 150W for 100W output, and it needs to be larger than the actual power used. 1. Leakage inductance transformers cannot be used on this board, such as microwave oven transformers, paging stations, and transmitters on the launching station. Several silicon steel sheets are inserted between the two primary and secondary stages of this type of transformer, and there is no-load current and power consumption. Very high. 2. The self-winding transformer is not suitable for this board. Most of the self-winding transformers are not up to the standard because the number of turns is not up to the standard. After connecting the drive board, the no-load current is huge and the drive board is burned out. 3. It is strictly forbidden to connect the high frequency transformer to this board, otherwise the drive board will be damaged Package 1x full bridge 50HZ bridge inverter drive DC to AC module
