Protections

Build-in temperature control cooling fan. It can not only effectively dissipates heat, but also effectively prolongs the lifespan of fan.

Over-temperature. The unit will shutdown automatically.

Output over-voltage, over-current and short-circuit protection

Start-up with delay and soft start.

It avoids high output voltage striking.
