Feature

●DC DC converter is widely used for storage batteries, power transformers, adjustable regulated power supply for DIY, industrial equipment, 9 to 12V, 12V to 18V, 18V to 24V, etc.
●Designed with voltmeter, the voltmeter error is ± 0.1 V, the measuring range is 5 V ~ 35 V.
●The touch switch changes the measurement of the input or output voltage, and an indicator light indicates which voltage is measured.
●The maximum output current can be up to 4 A; it is recommended to adjust the working current to approx. 2A and add a heat sink at more than 2A.
●Step-up converter uses the internal vibration frequency of 400 kHz, belong to the second generation of switching voltage regulator, low consumption, high efficiency.


Description

Input and output have screw terminals for convenient connection, even without soldering iron, and hold solder pad for solder connection.
Technical data:
Input voltage: 4.5V-32V.
Output voltage: 5V-35V (adjustable).
Max. output current: 4 A.
Efficiency: 92%.
Output ripple: 30 mV
Switching frequency: 400 kHz.
Operating temperature: -40 ~ + 85 °C.
Size: 66 x 36 x 14 mm / 2.59 x 1.41 x 0.55 inches.
Note:
1. If the input voltage is below 4.5V, the voltmeter will not work and will not display2. The input voltage must be at least 1V higher than the output voltage.
3. If the power is above 20W, a heat sink is recommended to improve heat dissipation.
4. If the output voltage always corresponds to the input voltage and cannot be adjusted, please turn the potentiometer more than 10 circles counterclockwise. The voltage can then be adjusted normally.
Package includes:
1 x step-up converter module.
