1. The module uses imported high-quality chips, high efficiency (95% higher), at the same time, the calorific value is small, and the current can reach 5A. At the same time, the output current is controlled with the TI op amp to make the overall output very stable. 2. This module uses Sanyo filter capacitors with low ESR, which can make the ripple voltage as low as 50mV! 3. This module uses machine patch, reflow soldering, and each module undergoes two hours of aging test before shipment to ensure high reliability. Module nature: non-isolated buck module Rectification mode: non-synchronous rectification Input voltage: 5V-32V Output voltage: 0.8V-30V Output current: adjustable 5A Conversion efficiency: 95% (high) Switching frequency: 300KHz Output ripple: 50mV (large) 20M bandwidth Load adjustment rate: ± 0.5% Voltage adjustment rate: ± 2.5% Working temperature: -40 ℃ to + 85 ℃ LED constant current drive Usage: 1. Determine the operating current and high operating voltage of the LED you need to drive; 2. Adjust the constant voltage potentiometer to adjust the output voltage to about 5V. 3. Use a multimeter 10A current block to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined LED working current; 4. Adjust the constant voltage potentiometer to make the output voltage reach the high working voltage of LED; 5. Connect the LED and test the machine. (Steps 1, 2, 3, and 4 are that the module input is connected to the power supply, and the output is no-load without LED lights.) colour:as shown Material:ABS + electronic components size:51×26.3x14mm Package Contents: 1x Drive power module Only the above package content, other products are not included.
