High quality shell
The use of flame retardant material shell, with better thermal performance, safe and reliable

Waterproof design
Have organic silicone potting With waterproof, dustproof, shock effect, suitable for a variety of harsh environments.

High conversion rate
Using a new high-quality components, synchronous voltage regulator technology, conversion efficiency of more than 90%, very low heat, power is enough, work stable
Multiple intelligent protection
With over-current, overvoltage, overheating, short circuit and other automatic protection function, when the input is not within the range of voltage, built-in protector automatically cut off the circuit, when the input voltage back to normal range, it returned to normal work. The use of re-irrigation seal waterproof design, all-round protection more stable and reliable!
