Specification: Input voltage: DC 5.0-32V Output voltage: DC 0.8-30V Output current: 5A(MAX), maximum output current per channel! ! ! Number of output channels: four channels Minimum voltage drop requirement: 1.2V, that is, (VIN- VOUT)1.2V Voltage regulation method: precision potentiometer (turning clockwise increases the output voltage, and turning counterclockwise decreases it) Maximum conversion efficiency: 90% Protective measures: anti-reverse connection protection at dual-channel input terminals Notes: 1. Adjusting the potentiometer clockwise increases the output voltage, while adjusting it counterclockwise decreases it. 2. Because the potentiometer is a multi-turn precision potentiometer, adjust it counterclockwise several turns when using it for the first time. Otherwise, the voltage adjustment be ineffective and the output voltage not change. 3. This module is a step-down power supply module. Therefore, the supply voltage must be higher than the output voltage, with a voltage difference of at least 1.2V. 4. The maximum output current per channel is 5A. It is recommended that users limit the continuous current to approximately 3A or implement additional cooling measures.
