1, first you have to remember, this is a (AC or DC input may be) of the power conversion module (input, regardless of polarity), so the inputs are two red lines

2, the input AC: between the voltage range AC16V-28V, please do not do less than 16V higher than 28V. Input DC: voltage range between DC8V-40V, please do not do less than 8V higher than 40V.

3, section baby can work long 4A peak 5A, which means you can load device 20W or less long-term stability without adding any heat sink. Performance is very stable, full power enough.

4, all the components are imported, synchronous rectification, the plastic casing, waterproof, shock, moisture and dust.

5. Enter the high-voltage transient protection, output overcurrent protection, output short circuit protection, chip overheating protection.

6. Applications (Common Application): Surveillance cameras (CCD Camera); monitoring equipment (CCTV System); router (Gateway); any other applications to 12V electronic equipment, etc. ... ect
