⚠ Precautions

• The product operates in step-down mode, so ensure that the input voltage is higher than the output voltage
• The power supply range for this product is Dc 5V~30v. Output will be disabled if the input voltage is lower than 5.0V due to undervoltage lockout, and the device may be damaged if the input voltage exceeds 30V. lt is recommended to use a power supply ranging from 5V to 30V.
• When supplying power to inductive and capacitive loads, it is recommended to connect the load before turning on the device output.
• When outputting high power, some heat generation is normal. lt is recommended to use the device in a well-ventilated environment.
• Please remember not to connect power to both power ports of the device simultaneously, as simultaneous power supply may potentially damage the input source with lower voltage.
• When charging batteries, it is strongly recommended to add a reverse current protection module (such as a Schottky diode) to the output end to protect the device from damage.
