PRODUCT FEATURES

Module properties: Non isolated  booster module (BOOST)

The input voltage: 12 to 28 v (output) must be greater than the input voltage

Output voltage: continuous adjustable (14-30 v) (input voltage must be smaller than the output voltage)

Output current: < 4 a (MAX)

Input current: < 8 a (MAX)

Output power: natural cooling 75 w or less (MAX)

Can easily drive 40 w ~ 75 w notebook computers Including the dual-core 17 inch laptop.

After the test, with A 12 v battery with 17 inch HP 8710 w notebook (original charger 19 v 7.1 A) the nominal value of output, standby for 30 minutes, (the test process, the instantaneous maximum current of 3.42 A), temperature of about 45 ° C module.

Conversion efficiency: 94% (16 v input measured output is 19 v 2.5 A) (for reference only)

The output ripple: 2% (MAX) 20 m bandwidth (this data is provided by factory!

Working temperature: industrial grade (- 40 ℃ to + 85 ℃) (ambient temperature more than 40 degrees, please reduce power use, or enhance heat dissipation)

With temperature rise: 45 ℃

Load regulation: plus or minus 0.5%

Voltage regulation: plus or minus 0.5%

Dynamic response speed: 200 us 5%

Equipped with short circuit protection: no (please input fuse or protective circuit!)

Input reverse connect protection: no, please add meter circuit if necessary.

Connection mode: free welding terminals.

The advantages and disadvantages of products:

1, this article adopts the latest step-up IC chip, low starting current, low consumption, low fever, good waveform, the output of high efficiency;

2, input and output are made 35 v 1000 uf series high frequency low resistance capacitance, the condition is more stable and reliable.

3, unique low voltage work design, start input voltage must be greater than 12 v, small startup current, after the work input voltage instantaneous fell to 10 v can be normal output, ignition time also can ensure the normal order of the output voltage (now this functionality for testing, hope that the customer give us feedback information in time, in order to improve product. Because of the different models, the car battery power level is different, temporarily cannot guarantee that every car can reach the ideal effect.)

4, low voltage work need input wire as short as possible, as thick as possible, preferably module directly from the battery to electricity, on the position near the battery, the cross-sectional area of not less than 2.5 square millimeter, of course, with four square line effect is better.

Scope of application:

1), DIY one output adjustable car power, only need to input your access to the 12 v power supply, the output voltage can be (14-30 v) free continuous adjustment, but the output voltage cannot be lower than the input voltage.

2), universal laptop mobile power supply: input can be used for 3 to 4 day lithium battery series (voltage) between 12-16 v or using a 12 v battery, output regulation voltage > input (output) into your laptop can work.

3), booster charger: you can use the 12 v power supply is higher than 12 v battery charging, such as the 24 v battery charging.

4), for your electronic equipment power supply: as long as you need to adjust voltage the voltage and current shall not exceed the rated current (voltage * current < 70) can be normal work.

5) before, system level power supply: in DIY a project, for example you have only 12 to 18 v power supply, and you need about 20-30 v power supply circuit, the module will be your best choice, simply adjust the output voltage can work, easily achieve efficient high-power booster.
