Protection
Over voltage
115~150% rated output voltage. In latch mode, the power supply shall return to normal
operation only after the power is turned on again.
Short circuit
In hiccup mode, it will recover automatically after fault condition is removed.

Note: 1. To make the driver operate properly, the load voltage must be controlled above the minimum voltage
which
close to 50% of the maximum output voltage is from any given mode.
2. The dimming signal can be less than 1V. As it is for 0-1V ,the output current can maintain 10% of the rated output
current, but the connected LEDs may flicker. It's strongly recommended that keep dimming voltage bigger than 1V.
3. It is not allowed to connect the GND of dimming to the output, or the LED driver can not work as normal.
