Basic attributes Modular nature: non-isolation pressure relief (buck) Rectifier: non-synchronous rectifier Input voltage: 3.2v-40v Output voltage: 1.25 v-35v Output current: 3a (maximum) Conversion efficiency: 92 per cent (highest) Switching frequency: 150 khz Output ripple: 30mv (maximum) Load adjustment rate: ±0.5% Voltage adjustment rate: ±2.5% Working temperature: - 40°C to+85°C Peripheral size: 43x21 x 14 (long x wide x high) (mm) Product characteristics: ★ The module uses a high-quality lm2596 chip, high efficiency (up to 92%), low heating capacity, easy to carry more than 3a (short time) current, long-term work is recommended to use less than 2.5a current, plus heat dissipation (more than 10w output). ★ This module uses machine patch, backflow welding, and each module is tested two hours before shipment to ensure high reliability. ★ This module has accumulated more than 15000 films since the opening of sales. it still can maintain 100% of the praise rate, has been tested, the praise is the tide, is indeed your purchase. Input 3.2v - 40v output 1.25v - 35v Input voltage range: Dc 3.2v-40v (input voltage must be more than 1.5v higher than output voltage.Cannot lift pressure) Output voltage range: Dc 1.25 v-35v voltage is continuously adjustable and the maximum output current (up to 92%) is 3a. Points to note: Long-term work is recommended to use currents within 2.5a, with heat dissipation plates (over 10w output); as pressure-relief modules, keep the minimum 1.5v pressure difference in order to ensure steady output. ★ This module is an adjustable step-down module that can change the output voltage by adjusting the blue adjustable resistance on the module.The input - output pressure difference is 2 v, and the minimum output voltage is 1.25 v. ★ In-(negative input), in+(positive input), out-(negative output), out-(positive output), and out-(positive output), as indicated on the module, must be correctly connected, otherwise the module may be damaged. ★ This module has no output short circuit protection, if long output short circuit, may cause module damage. Voltage regulation: Access to power supply (4-35v), adjust the blue potentiometer knob (generally clockwise, counterclockwise, pressure-relief) and monitor the output voltage to the required voltage. Mode of connection: - welding, direct welding of the power cord to the input (output) port - solder inserts, which can be inserted into the insert needle or inserted on the hole plate through a lead line; or welds pcb directly after inserting the pin. Examples of applications: - a steady voltage power supply in a car, which can be adjusted by simply connecting the input of this module to the cigarette nozzle of the car, and the output voltage can be adjusted at 1.25-30v. it is very simple and convenient to supply many devices such as your mobile phone, mp3, mp4, psp charging, etc. - to supply electronic equipment, which can be easily transferred to the required voltage and solve the problem when the equipment needs 3-30v power supply and the corresponding voltage supply in hand. - system voltage test, the project can use this module to debug various voltage test system voltage range, very easy and convenient.. 1. there are too many types of materials to buy. you can send the list of materials you need directly to customer service and make it easy to shop quickly 4. please send a map or model to the customer and quote the goods you can't find 5 main materials and civilian tools 6. high price, large quantity can confirm the new price with customer service
