Product Description:

1. The module uses high-quality chips made in Taiwan, with high efficiency (up to 92%), natural cooling 12W (input voltage greater than 10V), and 20W heat sink. This module uses the original Sanyo filter capacitor with low ESR, and adds one more LC in the rear stage. The filter unit can make the ripple voltage as low as 40mV, which is suitable for most occasions.

2. This module uses machine patch and reflow soldering, and each module undergoes two-hour aging test before shipment to ensure high reliability.

Instructions for use:

This module is an adjustable automatic buck-boost module, which can change the output voltage by adjusting the blue adjustable resistor on the module. When inputting 9-35V and outputting 12V, the output current can reach 1A, and when outputting 5V, it can reach 2A.

The IN- (input negative), IN+ (input positive), OUT- (output negative), and OUT+ (output positive) indicated on the module must be connected correctly, otherwise the module may be damaged.

This module has no output short-circuit protection, if the output is short-circuited for a long time, the module may be damaged.

Application range:

1. Battery voltage stabilizer, you can stabilize the output of 12V battery (10-14V) at 12V, and the output of 24V battery at 24V.

2. The solar charging voltage is stable, which can stabilize the fluctuation voltage of the solar battery, and can charge the battery to avoid overcharging of the battery.

3. Power supply for your electronic equipment, ultra-wide voltage boost and boost design, suitable for a wide range of voltages.

4. The pre-power supply of the system is designed for ultra-wide voltage step-up and step-down, and the applicable voltage range is wide.
