new and high quality_x000D_ _x000D_ Power frequency sine wave inverter features:_x000D_ Instant load capacity, not easy to damage, low temperature rise, no interference._x000D_ Military 1.6mm double-sided PCB board._x000D_ The selected transformer should have a small no-load current. The leakage inductance should not be too large._x000D_ 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._x000D_ Large-sized no-load current or large leakage inductance will burn the tube. For example, the welding machine_x000D_ and the running light transformer cannot be used (the welding machine has no load current and leakage_x000D_ inductance, and the no-load current of the running light transformer is large)._x000D_ The toroidal transformer must be connected in series with a ferrosilicon magnetic core inductor._x000D_ The best of EI is also added. The shape of the square can not be added._x000D_ _x000D_ Notice Please:_x000D_ This board is an industrial frequency inverter board needs to cooperate with the power frequency transformer_x000D_ This product is a special commodity and needs to understand related technologies._x000D_ _x000D_ Recommended transformer power:_x000D_ 12V transformer with 7V 220V transformer 24V transformer with 16V 220V transformer_x000D_ 48V transformer with 32V 220V transformer 60V transformer with 40V 220V transformer_x000D_ _x000D_ Power frequency sine wave inverter motherboard function description:_x000D_ 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 for time), and the inverter is in standby mode._x000D_ 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._x000D_ 3. Normal automatic start-up of the battery: When the battery is under low-voltage for 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 for protection recovers to 14.7V per section after overvoltage for protection, the inverter automatically starts._x000D_ 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._x000D_ 5. Impact and short circuit protection: The inverter has real-time hardware wave-by-wave current limiting for protection, and software delay (400mS) short-circuit for protection plus power frequency isolation transformer. Improve the product's impact resistance and product reliability._x000D_ _x000D_ 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 for 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._x000D_ 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)._x000D_ _x000D_ Specification:_x000D_ Type: for DC/for DC Converter_x000D_ Voltage & Power: 12V 600W, 24V 1000W, 48V 1800W_x000D_ Dimensions: 5.5x10x10cm/2.17x3.94x3.94inch_x000D_ Quantity: 1 Pc_x000D_ _x000D_ Package includes:_x000D_ 1 x Pure Sine Wave Power Frequency Inverter Board _x000D_
