DC 7-35V to 1.25-30V Buck Converter Step Down Constant Voltage Current Regulator Charger Power Supply Module #090442 Description Feature: Module Properties: Non-isolated step-down module Rectification: Non-Synchronous Rectification Input Voltage: DC 7V-35V Output Voltage: DC 1.25V-30V ( Buck Mode, the input voltage must be 2V higher than the output voltage) Output Current: Adjustable maximum 3A Conversion efficiency: 90% Max. Switching frequency: 150KHz Output Ripple: 50mV (max) 20M Bandwidth Load Regulation: ± 0.5% Voltage Regulation: ± 2.5% Operating Temperature: -40 ℃ to +85 ℃ Dimension: 48 x 23 x 14 (L * W * H) (mm) If the power over than 10W, please install heatsink Battery Charging method: Make sure the recharge battery float voltage and charge current, input voltage of the module. adjust constant voltage regulator, the output voltage about 3V. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined charge current value; Adjust Constant regulator allows Output voltage reaches the float voltage; connected to the battery, try charging. (1,2,3,4 step input connect power, output do not connect battery.) LED constant current driver Usage: Make sure LED current and the maximum operating voltage; adjust constant voltage regulator, the output voltage about 3V. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined LED working current value; Adjust Constant regulator allows Output voltage Reach LED maximum working voltage; Connected to the LED, test. (1,2,3,4 take steps input connect power, output do not connected LED.) Package Include: 1x DC Converter Payment Method We accept only Paypal for both domestic and international.
