Application Notes:
1.The positive and negative input terminals must be connected correctly and negative voltage can not be input
to avoid damage to the power supply.
2.Due to the large input current, please pay attention to the voltage drop of the wiring, to ensure the power
supply to work properly.
3.At dim off,LDH output voltage will drop to the same level as input voltage.To get luminaires complete dark,
please make luminaires are light off when they are driving by the input voltage.
