100% brand new and high quality
OOTDTY Power frequency sine wave inverter features:
Instant load capacity, not easy to damage, low temperature rise, no interference.
Military 1.6mm double-sided PCB board.
The selected transformer should have a small no-load current. The leakage inductance should not be too large.
The no-load current of the toroidal transformer should be less than 0.1A, 0.3A below the EI shape, and 0.5A below the square shape.
Large-sized no-load current or large leakage inductance will burn the tube. For example, the welding machine
and the running light transformer cannot be used (the welding machine has no load current and leakage
inductance, and the no-load current of the running light transformer is large).
The toroidal transformer must be connected in series with a ferrosilicon magnetic core inductor.
The best of EI is also added. The shape of the square can not be added.
Notice Please:
This board is an industrial frequency inverter board needs to cooperate with the power frequency transformer

Power frequency sine wave inverter motherboard function description:
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 over-voltage protection: When the battery voltage is higher than 14.7V per section, the inverter will also turn off the inverter and enter the standby mode.
3. Normal automatic start-up of the battery: When the battery is under low-voltage protection, when the solar energy or wind power charges the battery to charge 12V per section, the inverter automatically starts to output the AC voltage to supply the load. When the battery overvoltage protection recovers to 14.7V per section after overvoltage protection, the inverter automatically starts.
4. Temperature-controlled fan and over-temperature protection: The fan will not turn when the inverter works normally. When the temperature is too high, the fan will run automatically. When the temperature drops, the fan will automatically stop running. When the fan is damaged and the temperature is too high, the inverter will turn off the inverter and enter the standby mode. When the temperature drops, it automatically starts the inverter and outputs AC power.
5. Impact and short circuit protection: The inverter has real-time hardware wave-by-wave current limiting protection, and software delay (400mS) short-circuit protection plus power frequency isolation transformer. Improve the product's impact resistance and product reliability.
Main board adopts high power and low internal resistance TO247 package Large MOS tube Large power loss Low electrolytic capacitor Uses high frequency low loss to ensure energy source Constant power supply stability to ensure MOS tube is not easy to damage Imported op amp integrated circuits ensure accurate and stable double-layer quality of each protection circuit Circuit board heat is low This motherboard is measured by the 48V power supply to achieve full 1800VA. The same motherboard with low-voltage power supply is proportional to the decline of less than 1800VA.
If the machine is installed with large no-load current, it needs to connect the inductor in series at the low voltage end of the transformer (the toroidal transformer must be connected to the inductor).
