Output: the highest DC 1.25V
Specification: 72x40x33mm
Mounting hole distance: 64.3x32.7mm,
The installation hole diameter: 3.2mm,
Net weight: 49g

Voltage regulation
Adjusting potentiometer knob. Clockwise adjust the high and low voltage generally. And the multimeter is used to monitor the output voltage reaches the required voltage

Connection mode
Loosen the screw terminals, power line directly into the hole and screwed, pay attention to positive and negative output end, the input need not be positive or negative; the plate is provided with a digital voltage meter 3P pin, convenient and direct plug

Application example
1 vehicle power supply. Only need to input the module is connected with a car lighter mouth power supply (12-24V), can adjust the potentiometer, the output voltage can be adjusted to 5V, for your mobile phone, MP3, MP4, PSP charging and many other digital equipment power supply, is very simple and convenient. Or by 24V adjusted to 12V DC power amplifier board mounted within the 12V2.5A use (such as the TDA7297, the power amplifier board).
2 the power electronic devices, when equipment requires 3-40V supply and the corresponding voltage power supply by hand, this module can be convenient to put the voltage to the desired voltage (within 1.25-38.5V), to solve problems.
3 testing system, a project can debug the working voltage range of various voltage test system using the module, very easy and convenient.

Note
Long time work in 2.5A (10W output) within the current, and pay attention to the cooling measures; because it is reducing module, in order to ensure the steady output, please keep the minimum pressure difference of 1.5V
