Power Requirements: Input DC 12V, minimum voltage 8V, maximum voltage 15V. Power recommendation: input power = maximum output 1.5. Output current: maximum 10A, please install cooling equipment when using high current. Output power: up to 200W with cooling equipment, up to 100W without cooling equipment. Please note: There is a slight color difference or discrepancy in kind, please don't mind, thank you!Due to the light and screen difference, the item's color may be slightly different from the pictures. Product parameters: 1: Output voltage: AC 12V. 2: Input voltage: DC 12V. 3: Applicable voltage: DC 8V~15V. 4: Module output: AC square wave. 5: The module input has anti-reverse connection protection. 6: Output frequency: 50Hz, can be fine-tuned up and down. 7: Module weight: 38 grams. 8: Working humidity: 5%~95%RH. 9: Working temperature: -25~85. 10: Module size: 66 x 40 x 16mm. Precautions: (1) The module does not have a voltage regulation function, and the output voltage is also low if the input voltage is low; (2) In order to the normal operation of the module, please connect a fuse in series at the input end by yourself, use a 10A fuse within the output power of 100W, and use a 20A fuse within the output power of 200W; (3) Choose a suitable transformer according to your own needs. Generally, the power of 10W is required to be 15W, and the output of 100W is more suitable to choose 150W. The power of the transformer should be larger than the actual power used; (4) Please use the transformer produced by the regular manufacturer, otherwise the module may be ; (5) Do not use leakage inductance and high-frequency , otherwise the module be ; Material: plastic colour: green Package Contents: 2 x Inverter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
