Over-heat protection Shut down the output when PCB temp. 110°C.
Auto recovers when temp. back to normal.
Over load protection When O/P voltage exceed its range, O/P current declines.
Auto recovers when the load is reduced.
Short circuit protection Shut down automatically if short circuit occurs.
Auto recovers after faulty condition is removed.

Short press = on/off control

Dimming memory: brightness will be the same as previously adjusted when turning off and on again.

Long press = stepless dimming

Every other long press: the light level goes to the opposite direction.
