3Pcs DC 7V-24V To DC 5V 3A USB Output Converter Step Down Module


3Pcs DC 7V-24V To DC 5V 3A USB Output Converter Step Down Module


This 5V USB output converter module is based on the KIS3R33S module specific design, the input voltage 7V to 24V, output voltage 5.01V 2.5A peak output current of 4A continuous output. Able to provide 3A continuous load current. The majority of players professional testing, with high efficiency, ultra-low loss characteristics, beyond perfect lm2596 power module. This module has a USB recognition. This module uses the original Sanyo low ESR filter capacitor voltage as low as possible so that the ripple 30mV, fully capable and linear power comparable. IN-(input negative), IN + (positive input), OUT-(negative output), OUT + (positive output) must be connected to the right, otherwise may cause damage to the module.

The USB output converter module has short circuit protection, 5A current automatic protection.
