VEN
NOTE: VEN
Precautions:
1 .The module does not support output short circuit protection board
2. The output current is greater than 20mA can get a better product overall performance
3. When -Vo overloaded,+Vo load is too light, it is recommended to increase the ground terminal +Vo dummy load resistor.

Please Note: this module only ± 15V Boost Module, not use for ±12V Boost. if you need ±12V, please you buy it in :
