Pure Sine Wave Inverter Board Mainboard Sine Wave Drive Board 12V/24V/48V/60V 600W/1200W/1500W/2000W Work with Transformer

Specifications:

If the purchase is 12V package, connect 12V a battery to unplug the jumper cap to 12V position, not more than 15V voltage, connect more than 15V to unplug the jumper cap to 24-72V position and adjust the undervoltage overvoltage precision adjustable resistance on the board counterclockwise lower and clockwise higher

This product is full of power, pure sine wave, circuit efficient and stable, no-load current is small, battery under voltage/overload/overheat protection installation is simple.

This motherboard is a power frequency inverter motherboard needs the buyer to cooperate with the power frequency transformer boost to have 220V output oh!

The selected transformer should have small no-load current. Not too much leakage. The no-load current of the ring transformer should be below 0.1A, below 0.3A of the EI shape and below 0.5A of the mouth shape. The no-load current is large or the leakage inductance is too large will burn the tube, such as the welding machine and the lamp transformer can not be used (the welding machine no-load current and the leakage inductance are large, the lamp transformer no-load current is large). Ring transformers must be connected in series with ferrosilicon aluminum magnetic ring inductors, EI is best also added, mouth shape can not be added.

Recommended transformer power:

12V power supply with 6V to 220V transformer

24V power supply with 12V to 220V transformer

24V to 220V transformer for 48V power supply

60V power supply with 30V to 220V transformer

72V power supply with 36V to 220V transformer

Sine wave inverter motherboard function description:

Take 12V as an example:

1. Battery low voltage protection: When the battery voltage is lower than 10.5V per section, the inverter will turn off the inverter (no AC voltage output at this time), and the inverter is in standby mode.

2. Battery overvoltage protection: When the battery voltage is higher than 14.7V per unit, the inverter will turn off the inverter and enter the standby mode.

3. Normal automatic start of the battery: when the battery is protected by low voltage, when the solar or wind power charges the battery to 12V each, the inverter automatically starts to output AC voltage to supply power to the load. Battery overvoltage protection When the overvoltage protection is restored to 14.7V per section, the inverter automatically starts.

4. Temperature control fan and overtemperature protection: the fan does not turn when the inverter is working normally, when the temperature is too high, the fan automatically runs, when the temperature drops, the fan automatically stops running. When the fan is damaged and the temperature is too high, the inverter shuts down and enters the standby mode. When the temperature drops, the inverter automatically starts and outputs AC power.

5. Impact and short circuit protection: the inverter sometimes real hardware wave by wave current limiting current protection, and software delay (400mS) short circuit protection plus power frequency isolation transformer. Improve the impact resistance of the product reliability.

The main board adopts high power and low internal resistance MOS tube with large power loss and low electrolytic capacitor with high frequency and low loss to ensure that the energy supply is continuous and stable to ensure that the MOS tube is not easy to damage the original imported op-amp integrated circuit to ensure that the protection circuit is accurate and stable double-layer high-quality circuit board with low heat output The main board has been measured 48V power supply power reached full 2000w

If the machine is installed with a large no-load current, it is necessary to connect the inductor in series at the low voltage end of the transformer (the ring transformer must be series inductor).
